Pennsylvania Traffic Signals

Picture	County	Date	Contributor
US 30 at Beatty County Road in Latrobe Typical signal installation in Pennsylvania with 12 inch yellow signals with black back plates.  Pedestrian signals are also a part of modern PennDOT signal installations.  The red indicators for US 30's main lanes feature strobes.	Westmoreland	8/11/2000	Jeff Kitsko
Morrell Place at School Place in Johnstown Typical signal installation in Johnstown with 12 inch red indicators and eight inch yellow and green indicators.  All streets have mast arm installations facing them.	Cambria	9/7/2002	Jeff Kitsko
West Pittsburgh Street at Westminster Avenue in Greensburg Typical mast arm signal installation in Greensburg.  All of the city's signals were replaced with this type in the mid-1980s.	Westmoreland	10/1/2002	Jeff Kitsko
Mission Road at PA 982 in Latrobe The street I grew up on finally has a traffic signal on it!  Just installed in September 2002, this signal was badly needed due to the amount of traffic that uses PA 982 which is the highway running left and right in the picture.  The signal on the right side of the picture is for the driveway of that house.	Westmoreland	10/15/2002	Jeff Kitsko
Ligonier Street at Avenue D in Latrobe* An old installation and the only wire span traffic signals in the City of Latrobe.  The main signal used to be a one piece Marbelite.
Ligonier Street at Chestnut Street in Latrobe The only pole mounted signal installation in the City of Latrobe.  What is interesting about this one is that these signals were recycled and used to be at the intersection of PA 981/Lloyd Avenue and Chambers Street.
Ligonier Street at Weldon Street in Latrobe Typical signal installation in Latrobe with 12 inch indicators and diagonal mast arm installations.
Concrete mounted signal in Latrobe This signal is rare in that it is mounted on a concrete pillar in the middle of the street to show drivers, with a flashing yellow indicator, that PA 981 northbound traffic has to go right onto Main Street.  The bottom indicator used to have a continual right arrow showing and on the opposite side a dual straight and left arrow.  Those have been burned out since the 1980s.  The signal facing left is a flashing red indicator for a minor street that intersects PA 981.
New Pittsburgh Signals Newer signal installation that utilizes black signals on a mast arm that faces each street, which is a step up from the old signals which were mounted on poles on the sidewalks.	Allegheny	10/28/2002	Jeff Kitsko
PA 148 southbound at Lincoln Way in McKeesport This is an older installation that McKeesport used to use, with 12 inch red and eight inch yellow and green indicators.
Emergency Signal Emergency signal for the Hartford Heights Volunteer Fire Department's fire house on US 30.  Another 12 inch red indicator with eight inch yellow indicators set of signals.  When a fire truck wants to enter the highway, the signals go from flashing yellow, to yellow, then to red.  The signals for the fire house flash red.	Westmoreland
Trucking Signal Signal installation on eastbound US 30 in Stewartsville, that operates the same way as the emergency signal above, but allows trucks to leave the terminal safely.
Berlin Signal Usual intersection control beacon assembly in a small town in Pennsylvania, with yellow flashing for the main route and red for the side streets.  Located in Berlin on US 219 and Main Street.	Somerset	11/14/2002	Jeff Kitsko
Erie Signal Signal installation at the intersection of PA 8 and PA 97.  The northern PA 97 begins here and travels to Union City.  What looks like air horns aimed to the left and right, to the right of the three-way signal, are emergency vehicle sensors.  Emergency vehicles approaching the signal will set off a light that will be received by the sensor and will trip the signals to all red.  All signals in Erie County are equipped with these.	Erie	12/8/2002	Doug Kerr
New-Old Greensburg Signal* For some reason, the signals were replaced by the poles and masts were not.  This is southbound on US 119/PA 819 at Green Street.	Westmoreland	12/30/2002	Jeff Kitsko
US 119 southbound at Trolley Line Avenue in Youngwood An old installation for the Bunchner Industrial Park.  In the early 1980s, these signals were on flash mode, but by the late-1980s were put into normal operation.  The blank sign to the right of the left turn signal is an electronic no left turn sign that lights up if a train is crossing Trolley Line Avenue.
Railroad Signal This installation is on Trolley Line Avenue at the railroad crossing mentioned mentioned above.  These are like the fire station signals, with 12 inch red and eight inch yellow and green indicators, flashing yellow in the place of the green indicators.  When a train crosses, the signal trips and goes into a typical yellow then red phase.  The red indicators appear to be 3M Programmed Visibility Signal heads.
US 119 northbound at County Home Road in South Greensburg* A signal installation in South Greensburg on US 119, which shows what a typical 1970s-era PennDOT assembly looked like.  The only modification to this installation was that the doghouse signal replaced a regular three head signal to permit left turns.
US 119 northbound at Fairview Street in South Greensburg* Further north on US 119 shows a plain four-way signal.  The pole mounted signals for US 119 have a modified red indicator with what looks like another signal head attached to where the original indicator would have been.
All traffic must turn right Signal on South Maple Avenue in Greensburg informing drivers that all traffic must turn right onto East Fourth Street with a continuous red indicator and right arrow.
US 119 southbound at Ridge Avenue in Homer City A rare wire-span signal installation on PennDOT maintained highways.  This intersection is where PA 56 leaves US 119, off to the left, to head towards Johnstown.	Indiana	1/13/2003	Jeff Kitsko
US 119 southbound at SR 2017/SR 3011 in Black Lick* A signal installation left over from the 1970s.  This intersection is used by trucks heading to the Edison Mission Energy's Homer City Generating Station via SR 3011 off to the right and SR 2017 is to the left.
Frackville Signal Located at the intersection of Oak Street and Lehigh Street.  PA 61 turns left at the signal and PA 924 starts at the signal and heads north.  What is unusual is that the green indicators are 12 inch indicators and the red and yellow are eight inch.	Schuylkill	4/20/2003	Jeff Kitsko
Ashland Signal Located at the intersection of Centre Street and Hoffman Boulevard, with PA 61 turning left to continue north.  All of Ashland signals installations are two sets of four way 12 inch indicators, similar to a standard Michigan installation.
PA 441 southbound at Emaus Street Located at the intersection of Union Street and Emaus Street in Middletown.  Note that the main signal is a one piece Marbelite signal.	Dauphin
PA 441 southbound at Ann Street Located at the intersection of Union Street and Ann Street in Middletown.  PA 441 turns left at the light and Truck PA 441 starts to the right on Ann Street.  Notice that all of the signals are 12 inch red and eight inch yellow and green indicators.
PA 130 westbound at Slate Run Road* Intersection control beacon just east of Greensburg, which was much needed after numerous accidents at this intersection.  Has since been replaced with a regular signal installation.	Westmoreland	5/24/2003	Jeff Kitsko
US 30 westbound at Lincoln Way* An older installation in Circleville with the signals for the inner lanes on US 30 using eight inch red and yellow indicators and 12 inch green indicators.  The signal for the left lane also has a 12 inch green arrow.
Lincoln Way at Henderson Road in White Oak I remember when this installation was the only one of the two located here that actually operated.  The one ahead used to just be in continual flash mode.	Allegheny
Lincoln Way at State Street in White Oak Another installation that is partially new and partially old.  The old parts are the pole mounted signals and the new is the three-way main signal.  A black four-way signal used to be here, but was replaced and they didn't even have the decency to match the color!  Until 1946, PA 48 used to turn right here to head towards US 30.
Versailles Avenue at Freemont Street in McKeesport Located in on "VER-sales" Avenue, shows a four-way signal installation with tunnel visors for the yellow and green indicators and cut-aways for the red.
Versailles Avenue at Evans Street in McKeesport Further down "VER-sales" Avenue, with signals for Evans Street using 12/8/8 signals, but with tunnel visors for the ones facing right and cut-aways for the ones facing left.
Evans Street at Fifth Avenue in McKeesport At the intersection where UPMC McKeesport Hospital is located, off to the right.  The three head signal closest to the camera was damaged at one point when the green indicator was knocked off.
PA 148 northbound at Queen Street in McKeesport* Typical older McKeesport installation with 12 inch red indicators and eight inch yellow and green indicators.
PA 148 northbound at Elm Avenue in McKeesport* Installation that is a simplistic two signals in each direction, and allows a left turn onto Elm Avenue.
PA 148 northbound at UPMC in McKeesport* Another older installation that uses green poles.
PA 148 northbound at Hartman Street in McKeesport* I grew up seeing this signal a lot, because my maternal grandparents lived on Hartman Street.
PA 148 northbound at Westinghouse Street in McKeesport* Another installation where the main signals are newer than the pole mounted ones.
East McKeesport Signal Typical installation with mast arms and 12 inch indicators.
Fifth Avenue at Patton Avenue Typical Wilmerding installation with mast arms and 12 inch indicators.
Patton Avenue at Middle Avenue Another Wilmerding installation at the street used to access PA 130 East, which is the highway that utilizes the overpass ahead.
Warren Signal Dueling signals at this intersection with some kind of high-intensity red indicator.  Also the signal facing the right in the background has elongated visors angled downward.	Warren	6/2/2003	Doug Kerr
Warren Signal A four-way signal with that same high-intensity red indicator.
Ridgway Signal A wire-span signal at the intersection of PA 948/Main Street and Penn Avenue.	Elk
Bradford Signal On PA 46 at East Main Street with dueling three-way signals.	McKean	7/6/2003	Doug Kerr
Pottstown Signal Standard signal installation for Pottstown, which is similar to New Jersey signal installations.  This one is located on High Street, which used to be US 422.	Montgomery	7/12/2003	Jeff Kitsko
I-476 Ramp Metering Signal In the mid-1990s, PennDOT concluded that this new urban Interstate would be like all others across the country, and sport ramp metering signals.  They operated from 1999 to 2001, and were shut off because of the lack of a central computer-software system.  On November 16, 2004, four were put back into service including this one on the southbound on-ramp from Baltimore Pike.	Chester	7/13/2003	Jeff Kitsko
PA 309 southbound at Lanark Road in Center Valley An old installation with bent mast arms and louvered back plates.	Lehigh	7/14/2003	Jeff Kitsko
Mercersburg Signal Located at the intersection of North Main Street and Seminary Street.	Franklin	7/16/2003	Jeff Kitsko
McConnellsburg Signal Located at the intersection of the western terminus of PA 16 and US 522 in downtown.  Notice the 12 inch red, and eight inch yellow and green indicators.	Fulton
PA 66 northbound at Manor Road in Delmont Strange mix of signals without back plates and ones with back plates.	Westmoreland	8/12/2003	Jeff Kitsko
Technology Drive at old US 119 in New Stanton* PennDOT seemed to try its hand at mast arm signals in the 1970s using this style, before it refined it to the standard it uses today.  Straight ahead is the entrance to the SONY Technology Center, which opened after Volkswagen closed their plant.
US 30 at Hempfield Plaza and Hempfield Square in Greensburg It looks like a typical PennDOT signal installation, but its not.  Since this is a massive intersection, it is easier to be handled by wires than mast arms.	Westmoreland	8/27/2003	Jeff Kitsko
US 322 eastbound at PA 58 A Michigan-like installation in Jamestown at the eastern split of US 322 and PA 58.	Mercer	9/10/2003	Doug Kerr
US 15 southbound at PA 654 in South Williamsport A mast-arm installation with redundant signals on telephone poles.	Lycoming	9/27/2003	Doug Kerr
US 220 northbound at High Street in Port Matilda The only traffic signal in the borough at the busiest intersection in the borough.  The signals facing to the left are for US 322 eastbound traffic and the signals facing the camera are for US 220 northbound traffic.	Centre	10/10/2003	Jeff Kitsko
PA 255 at Arch Street in Saint Marys Unusual installation being that Arch Street's two adjoining sections come in at different angles to the intersection.  Notice the 12 inch red, and eight inch yellow and green indicators.	Elk	10/12/2003	Jeff Kitsko
Sykesville Signal* The only signal you'll find in this small borough.  This is at US 119 southbound and Park Street.  Notice that there are no redundant signals.	Jefferson
PA 28 southbound at Anderson Street in Pittsburgh This is actually the southern terminus of PA 28 in Pittsburgh with a kind of "smorgasbord" installation:  vertical signals, horizontal signals, signals on mast arms, span wires, overpasses, signals with back plates, without back plates, regular lenses, and 3M signal heads.	Allegheny	11/7/2003	Jeff Kitsko
Madison Avenue at East Ohio Street in Pittsburgh This looks like a standard Pittsburgh installation, but unlike the others, all of the signals are horizontal instead of vertical.
PA 130 westbound at McCrady Road in Churchill I have never seen this Churchill signal do anything besides flash, which is probably best since the intersection is on a bend and it is closely spaced with the signals for the I-376 on/off ramps and Penn Avenue.
US 30 eastbound at Village Drive/Marguerite Road in Greensburg This installation has been modified since it was first installed in the 1980s.  The original signals were attached to the mast arms by connectors, and because the intersection is on a hill, wind would blow through and turn the signals every which way.  Also, there used to be a signal on the pole at the far left facing the camera position, two on the support pole for the mast closest to the camera, and another on the support pole for the mast at the right, which were used for pedestrian crossing.  Now they have been replaced with crosswalk signals.	Westmoreland
US 30 eastbound at PA 981 in Latrobe* The site of numerous accidents over the years, with one involving a friend of my parents', this installation appeared in the early 1980s.  It replaced a simple 1960s installation, with one wire crossing diagonally through the intersection, and consisting of six signals:  two for each direction and turn signals for both directions of US 30.
US 30 eastbound at Arnold Palmer Drive in Latrobe Yes, the same one.  In fact his dealership, where I bought the car I had prior to my current one, is at the right of the picture where the cars are lined up.
US 219 southbound at Washington Street Twin four-way signals in downtown DuBois.	Jefferson	12/7/2003	Doug Kerr
US 119 southbound/PA 36 northbound at Findley Street in Punxsutawney Standard installation with two signals facing each direction.
US 119 southbound at Gilpin Street in Punxsutawney Three way flashing signal in Punxsutawney with a continuous right green arrow to keep US 119 southbound traffic flowing.
PA 997 northbound at Interstate 81 in Chambersburg Mast arm installation but no back plates on the signals and a four head signal for left turns instead of a doghouse.	Franklin	12/28/2003	Doug Kerr
US 220/PA 350 northbound at Business US 220 in Bald Eagle Cable hung installation with back plates at the current end of Interstate 99 at PA 350 and Business US 220.	Blair
US 20 westbound at PA 18 in Girard Unusual mast arm installation in that the arm is one piece that crosses over the highway, instead of two separate arms.	Erie	1/16/2004	Doug Kerr
PA 98 northbound at US 20 in Fairview Wire-span installation with emergency vehicle trip sensors.
PA 8 southbound at US 6 in Union City Mast arm installation without back plates and with 3M signals in the background.
US 6 eastbound at PA 89 in Elgin Intersection control beacon with a rare alternating flashing sequence with the indicator on one assembly lit while the other is off.
Old Pittsburgh Signals* Older signals were usually mounted on poles such as this installation at Commonwealth Place and the Boulevard of the Allies.  Sometimes, small curved mast arms were installed to increase visibility.	Allegheny	2/9/2004	Jeff Kitsko
Liberty Bridge at McArdle Roadway in Pittsburgh This installation takes a lickin' as the signals with their back to the camera can attest.  This is the intersection for traffic to access Mount Washington with its spectacular views of the city.
PA 51 southbound at PA 88 in Pittsburgh This is the intersection to see if you like traffic signals, since there are 24 signals for six directions.
North Elmer Avenue at Spring Street in Sayre Pole-mounted Marbelite signal heads that appear to be installed between the late 1960s and 1970.  They were originally green and have now been painted yellow.	Bradford	3/9/2004	Timothy Forbes
Lockhart Street at North Wilbur Avenue in Sayre Blinkers have been in service at this intersection for decades, but these particular signals were installed sometime after 1995.
PA 611/Broad Street northbound at Reed Street in Philadelphia A PennDOT-like 12 inch yellow signal with black back plates.  Charles Trainer of the City of Philadelphia Streets Department told me that Philadelphia began installing signals such as this around 1974.  He also mentioned that the mast arms on Broad Street south of City Hall are "stubby mast arms" so as to not interfere with the view of the building from PA 611.	Philadelphia	3/21/2004	Jeff Kitsko
Race Street at 13th Street in Philadelphia The standard City of Philadelphia signal installation with four poles that signals are attached to, with two facing each direction.  Since the majority of streets within the city are narrow, this setup maintains the cone of visibility requirement.
Market Street at Fifth Street/Independence Mall East in Philadelphia It walks like a PennDOT signal, it talks like a PennDOT signal, but something isn't right.  A red arrow?  PennDOT only approves signal installations, and does not run them, so Philadelphia bucked the trend for turn signals across Pennsylvania by tossing in their own flare with the red arrow.
East Main Street at College and Ford Streets Youngsville Old signal that, while not shown in the picture, is now used as a intersection control beacon.	Warren	4/11/2004	Doug Kerr
PA 27 westbound at US 6 in Youngsville Numerous signals, some with back plates and some without, at this complex intersection that not only involves highways but a railway.
US 119 at US 322 in DuBois An old PennDOT installation on US 119 northbound south of DuBois.	Clearfield	4/23/2004	Jeff Kitsko
Owens-Illinois Pedestrian Signal in Brockway View from US 219 northbound, the green indicators do something very unusual:  they flash.	Jefferson
Keystone Powdered Metals Company Pedestrian Signal in St. Marys View from PA 120 eastbound.	Elk
Northern Cambria Signal All of the signals in this borough have 12 inch red and eight inch yellow and green indicators on wire-span.  Some installations even have black back plates.	Cambria	4/27/2004	Jeff Kitsko
Carrolltown Signal The only traffic signal in this small, rural Cambria County town.
PA 271 southbound at South Street in Johnstown Typical old City of Johnstown installation with 12 inch red and eight inch yellow and green indicators on wire-span.
PA 271 southbound at Goucher Street in Westmont Installation at the main intersection in Westmont.  All of the signals have black back plates except the doghouses.
Goddard Boulevard at North Gulph Road in King of Prussia An unusual installation where all of the signals facing Goddard Boulevard are on pedestals, but the ones for North Gulph Road are on mast arms.  Also of note are the backlit street signs.	Montgomery	5/7/2004	Jeff Kitsko
Commerce Drive at West Pennsylvania Avenue in Fort Washington Another installation in involving a pedestal signal but the redundant signal is on a mast arm support pole.
Rices Mill Road at Greenwood Avenue and Longfellow Road in Cedarbrook Double your pleasure, double your fun.  Not just one 3M signal, but also the redundant signals on the support pole are 3Ms.  The reason is that the angle of the intersection require these.
PA 611 northbound at Wyandotte Road in Willow Grove Unusual sight where there are not only one four head turn signal, but three of them and one on a pedestal!  Most of these have been replaced with the five head "doghouse" signal since it incorporates a yellow arrow.  Also of interest are the louvered back plates on the two signals over the mainline.
US 30 westbound at Clover Hill Road Wynnewood Looking westbound at these dueling diagonal mast arm installations.	Montgomery	5/9/2004	Jeff Kitsko
US 30 westbound at Church Road in Ardmore These mast arms in Ardmore reminded me of somewhat of Australian installations I have seen on the Internet due to their angle over the street.
US 30 westbound at King of Prussia Road/I-476 ramp in Villanova Something unusual I noticed on some installations in District 6.  Some turn signals have cut-away visors for the green and yellow arrows and tunnel visors for the red indicators.	Delaware
US 30 westbound at Ronks Road in Ronks Simple wire-span installation with two signals facing each direction.	Lancaster
Somerset Signal On PA 601 southbound at PA 31.  All of the signals in downtown Somerset use 12 inch red and eight inch yellow and green indicators with black back plates on mast arms.	Somerset
PA 31 westbound/PA 381 southbound at PA 711 Intersection control beacon installation at the end of the PA 31/PA 381 multiplex and beginning of the PA 31/PA 711 multiplex west of Jones Mills.	Westmoreland
PA 60 southbound at Ingram Street Installation with signals for five different directions.  Notice the four-head turn signal, the programmable visibility signals on the poles, and a wire-span signal attached to the one pole.	Allegheny	5/16/2004	Jeff Kitsko
PA 60 southbound at Linden Avenue Simple two mast arm installation in Crafton.
PA 60 southbound at Noble Avenue All eight inch heads except for the turn signal which features an 8/8/8/12 configuration.  This is the intersection where PA 60 turns right off Steuben Street.
PA 60 southbound at Stratmore Avenue This is how Pittsburgh began to do signal installations in the 1980s:  all yellow, 12 inch signals with bubble back and box wire-span.
PA 60 southbound at Wabash Street Same theme in Pittsburgh's West End, but due to the narrow streets only one signal per direction per wire.
PA 837 southbound at Riverview Plaza Simple wire-span installation on the South Side of Pittsburgh, directly across from Point State Park, with a four-head turn signal.  Also of note is the top of One PPG Place poking up above the building.
Boulevard of the Allies at Cherry Way Another variation on the old Pittsburgh signals.  When necessary, a small curved wire-supported mast arm was used to enhance visibility.
Old US 119 at Painterville Road in New Stanton A simple two wire-span installation.	Westmoreland
Montrose Signal The only signal in this small Pennsylvania town, located on Main Street and Public Avenue	Susquehanna	5/24/2004	Timothy Forbes
PA 267 southbound at Stanley Lake Road in Friendsville Usual type of wire-span installation that PennDOT will erect, with the box style of layout.  Northbound traffic will see a "[RED] SIGNAL AHEAD" sign, with the "red" portion in LEDs that light when the signal is red and goes dark when the signal is green.
Breezewood Signal The consolation prize for not getting a full expressway-to-expressway interchange.  This is the only traffic signal on the entire length of Interstate 70.  The signal heads have 3M programmable visibility lenses.	Bedford	6/4/2004	Jeff Kitsko
Business US 322 westbound at Allen Street Old bent mast arm installation in State College.	Centre	6/6/2004	Doug Kerr
Allen Street at Easterly/Westerly Parkway in State College Typical installation seen in urban areas with a mast arm for all directions and signals with cut-away visors.
State College Emergency Signal Unusual emergency signal installation for Pennsylvania, taking a page from the typical Maryland emergency signal installation of 12 inch red, 12 inch yellow, eight inch flashing yellow signal configurations.  The lone signal head facing left is aimed at the fire station to indicate if the signal has stopped traffic.
Westerly Parkway at Business US 322 in State College Unusual to see 12/8/8 signals on mast arms.
East Pine Street at Sixth Street in Phillipsburg Twin four-way signals on a diagonal wire-span.
US 322 westbound/PA 53 northbound at Front Street in Phillipsburg Another set of four-way signals.
US 322 westbound at PA 53 in Phillipsburg The end of the multiplex of the two routes offers this box wire-span installation, with the opposing direction of travel an 8/8/8/12 left turn signal.	Clearfield
US 62 southbound at Pine Street in Warren Another signal in Warren with a high-intensity red.	Warren	6/19/2004	Doug Kerr
US 62 southbound at Petroleum Street Typical Oil City installation with signals on mast arms.	Venango
US 62/PA 8 northbound at PA 428 in Oil City Unusual installation with one angled mast arm facing PA 428 and another facing the camera which I have only seen in the Plain States.
US 62/PA 8 southbound at Front Street in Franklin Standard wire-span box installation with 12 inch indicators and cut-away visors in Franklin.
US 62/PA 8 southbound at Elk Street Standard Franklin installation with rust colored mast arms, and this one with high-intensity red indicators.
US 62/PA 8 southbound at US 322 in Franklin Another installation at the beginning of the US 62/US 322/PA 8 multiplex, with a doghouse signal on the support pole.
US 62/PA 8 southbound/US 322 westbound at 11th Street in Franklin Unusual installation with two four-way signals and all at one end of the cable, with lane use signs at the end closest to the camera.
US 62/PA 8 southbound/US 322 westbound at 12th Street in Franklin Angled mast arm installation.
US 62/PA 8 southbound at 14th Street in Franklin Another angled wire-span installation with two four-way signals in a 12/8/8 arrangement.
US 62/PA 8 southbound at 15th Street in Franklin Caution flashers at an intersection where US 62/PA 8 change directions.  The extra head on the signal facing to the left is a continuous green arrow, to allow traffic turning right to proceed.
US 6 eastbound/US 19 northbound at Plank Road in Venango Flasher with a continuous green arrow for traffic continuing on US 6/US 19.	Crawford	6/19/2004	Mark Sinsabaugh
Temporary NYSDOT Signals* What is this?  Dark green signals on a wire?  Those aren't PennDOT signals!  Since NYSDOT is rehabilitating the bridge at Hancock, New York, they got to pick the signals for single lane control.	Wayne	7/2004	C. C. Slater
US 6 eastbound at PA 191 in Honesdale Double angle mast arm with all signals featuring eight inch indicators except for the duel protected/permissive left turn arrows with the MUTCD standard 12 inch indicator.
US 202 northbound at Mall Boulevard in King of Prussia The typical Pennsylvania installation, except the signals for the thru lanes did not get back plates.  Notice the doghouse signal attached to the pole at the right and the pedestal signal on the corner at the left.	Montgomery	7/3/2004	Jeff Kitsko
Caution!  Union/Confederate Soldier Crossing The only traffic signal on the Gettysburg National Military Park on US 30 at Reynolds Avenue which is part of the battlefield tour route.	Adams	7/5/2004	Jeff Kitsko
US 30 westbound at Falling Spring Avenue in Chambersburg* Yes, even temporary signals in a construction zone follow the PennDOT-standard down to the back plates.	Franklin
PA 56 eastbound at Hyde Park Road in Leechburg An Maryland-like installation in Pennsylvania?  Well, it is economical in that it uses one wire in a "Z" alignment.  If you look closely, you can see the turn signal's red indicator and green arrow lit simultaneously.	Westmoreland	7/11/2004	Jeff Kitsko
PA 199 southbound at Lockhart Street in Sayre Sometimes not all signals will get back plates, but just ones in the eastern and western directions such as here.  Also note the 8/8/8/12 signal at the left.	Bradford	7/18/2004	Doug Kerr
US 30 westbound at Agnew Road in Lincoln Heights Old installation that was typical of Pennsylvania ones at intersections involving four lane highways, with no left turn protection provided.	Westmoreland	7/30/2004	Jeff Kitsko
US 30 westbound at Pennsylvania Boulevard Old installation that unlike the previous one, gives a protected turn for eastbound traffic.  These signals are located at the Monsour Medical Center in Jeannette, which is located on the right.
US 30 westbound at Lewis Avenue The only thing that has changed with these signals is that the signal for the eastbound left lane had to be replaced after it was damaged.
US 30 westbound at Lowry Avenue The main route into and out of Jeannette is via this intersection.  The doghouse signals for both directions were added in the 1980s to provide people a chance to turn.
US 30 westbound at Malts Lane in North Huntingdon* Years ago, the two-way signal in the middle of the cable used to be a four-way signal.  The signals for both directions on US 30 were removed and individual signals installed for the inner lanes.
US 30 westbound at Carpenter Lane/Leger Road in North Huntingdon Simple two mast arm installation, with the signals for the westbound lanes and Leger Road 3M Programmable Visibility signals because of the angles of the intersection.
US 30 westbound at Magnus Lane in North Huntingdon This is an example of an "X" span installation where the cables cross in the middle of the intersection.  Similar to what happened at Malts Lane, but instead the signals for the side street was separated and the signals for US 30's inner lanes completely replaced.
US 30 westbound at Graham Avenue Mast arm installation in East McKeesport.  The reason for the 3M Programmable Visibility signals is that there are two intersections closely spaced in this area.	Allegheny
Port Perry Road at East Pittsburgh-McKeesport Boulevard in North Versailles* Simple wire-span box installation with both sides getting four indicator protected/permissive turn signals.
East Pittsburgh-McKeesport Boulevard at Maryland Avenue in North Versailles An older installation at one of the entrances to the former Eastland Mall in North Versailles.
East Pittsburgh-McKeesport Boulevard at Eastland Mall Versailles* An old installation that was reduced to being warning signals, with the signals for East Pittsburgh-McKeesport Boulevard flashing yellow, and the entrance to the former Eastland Mall flashing red.  The signals with only two indicators used to have 12 inch green indicators such as the one facing on an angle to the right.
Fire Signal Old signal along East Pittsburgh-McKeesport Boulevard to warn drivers if fire equipment will be entering the roadway.  The signals flash back and forth, while the darkened box in the center lights up "FIRE."
PA 148 southbound at Fifth Avenue in McKeesport Simple one wire-span installation with signals for all three directions at this "Y."
Pittsburgh-McKeesport Boulevard at Lebanon Church Road in West Mifflin Dual wire-span installation with the two turn signals and their related thru lane signals on one cable and the directions with no turn signals on the other.  The two signals at the left feature angled green arrows to direct traffic to turn right.
Lebanon Church Road at Buttermilk Hollow Road in West Mifflin* Another simple one wire-span installation with 3M PVs.  The reason for the thickness of the wire is that a phone cable is also carried across the roadway at this point.
Lebanon Church Road at Regis Avenue in West Mifflin Another dual wire-span installation, but with a modern twist as all of the signals have back plates.
Curry Hollow Road at Arbor Lane in Baldwin More old signals with a protected/permissive left turn signal for the left lane.
Curry Hollow Road at Curry Hollow Centre in Baldwin The usual application of turn signals for the main route and only two signals for each side street.
Curry Hollow Road at Keeport Drive in Baldwin A mix of old, the faded yellow ones, and new, the doghouse signal facing the opposite direction.
Curry Hollow Road at Jefferson Memorial Park Cemetery in Baldwin Another case of old and new, with the same results as the installation above.
Brownsville Road at Broughton Road in South Park In the not-so-famous South Park, which is in the background, at one of the most complex intersections that features three individual signal installations which can be seen in the picture.  Also, the left turn signal features an angled arrow.  Brownsville Road turns to the left and Broughton Road begins at the right.  Notice that "RED" is in red on the "STOP HERE ON RED" sign.
Broughton Road at Baptist Road in Bethel Park More old sun faded signals, and keeping the 12 inch indicators for the main route and eight for the side street concept except for the green arrow indicator on the left side.
PA 88 northbound at Milford Drive in Bethel Park Mix of signals with tunnel visors and ones with cut-away visors, however, the turn signal for the opposite direction should have tunnel visors because of the arrow.
Connor Road at Oregon Trail/Greenridge Road in Mount Lebanon Change of pace, where all directions get 12 inch indicators instead of the side streets getting eight inch indicators.
US 19 southbound at Highland Road in Mount Lebanon A new twist to the protected/permissive left turn signals, where instead of having the arrow below the green indicator it is beside it.
US 19 southbound at Fort Couch Road in Bethel Park* An installation in the process of being replaced, and with good reason.  The signals are sun faded and you can barely see the red indicators for the turn signals.
US 19 northbound at Connor Road in Mount Lebanon Simple four way installation with an auxiliary signal facing each direction.
US 19 northbound at Mount Lebanon Boulevard in Mount Lebanon Three way installation with an auxiliary protected/permissive turn signal for the opposite direction, but all the signals have cut-away visors.

US 19 northbound at Altoona Place in Mount Lebanon The main route gets a two-way overhead signal, while the side street gets only pole mounted signals.
PA 121 northbound at Williamsburg Road/Morrison Drive in Mount Lebanon Wire-span mounted signals along with pole mounted signals.  Time has taken its toll on these aside from the fading, but also the signals on the pole having lost a couple of visors.  You can see the finials used to attach the signals to their support tubing.
Lane-Use Signals Typical lane-use signals on PA 121 northbound in Green Tree.
PA 60 northbound at Crafton Avenue in Crafton Old signalsthat feature "WAIT/WALK" signal heads, which are the single heads facing the sidewalks.
US 30 westbound at Old Steubenville Pike/West Allegheny Road in Imperial Complex intersections require complex signal installations, and this one is no different with 17 signals facing five directions.  PA 978 used to continue to the right on West Allegheny Road before 1976.
Fort Duquesne Boulevard at Stanwix Street in Pittsburgh Wow!  Another red arrow in the Commonwealth of Pennsylvania!  However, just like in Philadelphia, this is a City of Pittsburgh installed and maintained traffic signal so they can do as they please.  Ahead is Point State Park and the silver building on the left houses KDKA-AM, the first commercial radio station in the United States, and KDKA-TV/DT.	Allegheny	8/1/2004	Jeff Kitsko
PA 418 northbound at Morefield Road/Maple Drive in Hermitage A mix of 12 inch and eight inch indicators and interesting ways to connect them together.	Mercer	8/6/2004	Jeff Kitsko

US 6/US 322 eastbound/PA 18 northbound at PA 18 in Conneaut Lake An interesting installation as only one signal has a back plate and the four-way signal cluster in the middle.	Crawford
PA 18 northbound at Plum Street in Harmonsburg These twin one-piece Eagle signals are the only ones in the tiny village.
PA 18 northbound at Beaver Street/Cussewago Street in Springboro The only signal here is this four-way installation that features no redundant signals.
PA 18 northbound at US 6N Now a one piece Marbelite signal, but this time black and in Albion.  No redundant signals in this installation as well.	Erie
US 6N eastbound at PA 98 in Lavery A pair of four-way signals with 12 inch red indicators with tunnel visors, and eight inch yellow and green indicators with cut away visors.  Another emergency vehicle trip sensor array in the middle.
US 6N westbound at Waterford Street/Ontario Street in Edinboro A rare sight with signals with back plates, and when all directions have signals with eight inch indicators.  Except for the doghouse signal, which is interesting with its wider than normal appearance and angled arrows to keep US 6N traffic flowing.
Red Signal Ahead An illuminated signal ahead sign with a twist.  When the signal is about to turn red, the "RED" flashes to alert drivers to slow down.  Usually installed on highways where signals are sparse.	Butler	8/8/2004	Jeff Kitsko
PA 68 westbound/PA 356 southbound at West 10th Avenue in Butler Old time Econolite signals at this intersection, with a protected/permissive four indicator left turn signal facing the opposite direction.
PA 68 westbound/PA 356 southbound at New Castle Street in Butler All directions get eight inch indicators, except for the 8/8/12-12 signal on the right with an angled green arrow.  Also, opposite that signal, there is a left turn signal that features 8/12/12 indicators which is the only time I have seen that setup.
PA 8 southbound at Diamond Street in Butler New twist on the standard City of Butler signal installation, stealing PennDOT's design of 12 inch indicators and back plates but keeping the rust colored mast arms and poles.
PA 8 southbound at Brugh Avenue/Morton Avenue/South Main Street in Butler A family of 12/8/8s, 12/8/8/12s, and even a 12/8/12 indicators in an installation combination of mast arm and wire-span.  Also note the simultaneous red indicator and green arrow.
PA 356 southbound at Spring Street in Butler Another all eight inch indicator installation, except for the green arrow facing southbound traffic, which makes for an interesting four-way signal.
PA 356 southbound at Saxonburg Road in Butler Triangular wire-span installation with four indicator protected/permissive turn signals, and a pole mounted doghouse at the left.
Fire Signal Located on East Pittsburgh Street in Greensburg, but this time a wire-span installation unlike its North Versailles counterpart.	Westmoreland	8/14/2004	Jeff Kitsko
PA 130 westbound at US 119/PA 819 This is a true representation of the new generation of signals the City of Greensburg installed in the early 1980s.
PA 366 westbound/Truck PA 56 eastbound at Freeport Street in New Kensington All directions except the one facing the camera gets 3M Programmable Visibility signals.
Freeport Road at Morgan Street in Natrona Heights Old signals with all 12 inch indicators for Freeport Road, and all eight inch indicators for the side streets including the parallel Broadview Boulevard.	Allegheny
Freeport Road at Alabama Avenue in Natrona Heights Old Econolite signals for Freeport Road including a protected/permissive left turn signal, and eight inch indicators for the side streets with two three-way clusters on Broadview Boulevard.
Power Outage! This is what signals look like when they are sleeping.  Shhhhhh!  Actually, the signals for the thru lanes were faintly flashing yellow during this interruption in power.  This is the same installation as shown in the first picture, except facing eastbound.	Westmoreland
US 30 westbound at Center Highway/Robbins Station Road in Circleville Mix of regular signals and 3M Programmable Visibility signals.  While appearing to be dark, the turn signal is lit, but there are louvers in the visors to shield thru traffic from its indication.	Westmoreland	8/15/2004	Jeff Kitsko
Broughton Road at Horning Road in Bethel Park Old sun faded signals just beyond the Brownsville Road at Broughton Road installation.	Allegheny
Bethel Church Road at Meadowbrook Drive in Bethel Park* Sister installation to the one above and just a football field length beyond.  Like the other signal, only one direction has both signals on the wire, which is the opposite direction here.
Fort Couch Road at Bethel Church Road in Bethel Park Typical wire-span installation for Bethel Park with the standard rust colored poles.
US 30 westbound at PA 217 in Latrobe* One of the first installations in the mid-1980s to use mast arms, 12 inch indicators, and black back plates.  This installation replaced a flashing beacon installation which has been moved to the intersection of US 30 west and West Main Street in Ligonier.  Notice the pedestal signals on the sides for pedestrian crossing.	Westmoreland	8/16/2004	Jeff Kitsko
PA 217 at Second Avenue in Derry The only traffic signal in the borough, which was just installed in 2000.
Main Street at PA 982 in Youngstown* Arnold Palmer and this, the only signal in this village, call Youngstown home.  The old four-way used to have black visors.
South Mill Street at PA 108/PA 168 in New Castle Two mast arm installation with pairs of signals for each direction.	Lawrence	8/29/2004	Doug Kerr

Business US 422 at Shenango Street in New Castle Mast arm installation with a 12/12/12-12 protected/permissive turn signal.
Business US 22 eastbound at Penn Center Boulevard in Wilkins Simplistic wire-span box installation that seem to be mirror opposites of the other side.  What is unusual is that the left turn signals do not have back plates, nor the signals facing left and right which is how early installations with back plates looked.	Allegheny	9/2/2004	Jeff Kitsko
Business US 22 eastbound at Kingston Drive in Wilkins A newer setup but similar to the one above, except with the doghouse signal on the left.  Also, the preceding signals with one not only for the through lanes and left turn lane.
Business US 22 eastbound at Northern Pike in Monroeville* Wire-span box assembly with signals with all 12 inch indicators.  The signal in between the left turn signal and the through signal on the right is newer than the other ones.  One day in 1998, after a nasty thunderstorm, I came through the area and discovered the yellow and green indicators ripped off the original.  The things that look like flood lights facing traffic are emergency vehicle sensors, which signals in the Borough of Monroeville have unlike the first three in this batch which are located in Wilkins Township.
Business US 22 eastbound at Duff Road in Monroeville* A contrast of new and old at this intersection.  Old wire-span signals being replaced with the new PennDOT standard mast arm for a new Sheetz convenience store that opened at the right.  The single indicators between the through lane signals are emergency vehicle sensors.
Business US 22 eastbound at Center Road/Stroschein Road in Monroeville* All directions get a preceding signal, except the one facing westbound traffic has eight inch indicators instead of the 12 inch ones facing this direction.  Also of note are the left turn signals (R/Y/GA-G) facing left and right.

Interstate Business Loop 83 northbound at PA 462 in York Changing it up yet again, this time with all directions getting 12/8/8 signals.
Interstate Business Loop 83 northbound at Parkway Boulevard in York Following the MUTCD to a tee!  The left turn signal gets all 12 inch indicators, since the MUTCD forbids eight inch arrows.  Even the signal facing left gets a 12 inch green arrow.  A contrast from the through lanes which get eight inch indicators.
US 222 southbound at PA 372 in Quarryville A Michigan-like installation, with two four-way signals on a diagonal wire.	Lancaster
US 222 northbound at New Street Typical installation in the City of Lancaster:  curved mast arms and signals with eight inch indicators.
One Way All Traffic Unusual red indicator and green arrow combination to alert drivers that US 222 traffic must turn right at the impeding split.	Lancaster	9/19/2004	Jeff Kitsko
Truck PA 441 northbound at Wood Street Another Middletown four-way signal with 12/8/8 indicators for all directions.	Dauphin

PA Turnpike at Business US 220 in Bedford Not one, but two R-Y-G/GA signals to control traffic from the Turnpike off ramp to northbound Business US 220 to take traffic to I-99/US 220.	Bedford
Reels Corners' Flasher Only signal in this small eastern Somerset County village.	Somerset
PA 179 westbound at PA 32 in New Hope Installation featuring a four indicator protected/permissive left turn signal.	Bucks	10/3/2004	Doug Kerr
PA 413 southbound at Lower Mountain Road in New Hope Unusual sight with signals with back plates on wire-span, and not in a box design.  Originally planned to be temporary, this installation was made permanent by Pineville to reduce accidents at the intersection.
PA 413 southbound at Winchester Avenue in Langhorne Single mast arm installation in a quiet neighborhood.
New Tyburne Road at New Falls Road in Levittown Not one, but two four indicator protected/permissive turn signals at this intersection.

Truck US 19 northbound at Patrick Place in Pittsburgh Another simple box wire-span installation.
West Newton Street at South Hamilton Street in Greensburg Old curved mast arm with signals with 12 inch indicators, except for the one facing right.	Westmoreland	11/10/2004	Jeff Kitsko
US 30 eastbound at PennDOT Drive/Old Route 30 in Greensburg New meets old at this installation.  When US 30 was rebuilt here in 1988, instead of the installation being replaced, another signal was added to each of its mast arms due to the addition of another lane.  The mast arm with signals facing away from the camera replaced the original one in 1992, same year the signals at the very left facing left were added.
PA 366 southbound at Riverview Plaza in New Kensington* Box wire-span installation with a doghouse signal that is younger than the other signals.  Also of note are the poles at the left with the tapered tops.	Westmoreland	11/13/2004	Jeff Kitsko
PA 366 southbound at Caldwell Avenue in New Kensington* A rare sight with one through signal on the mast arm and the other on the pole, instead of side-by-side.  Usually, both through signals are crammed overhead for better visibility.
PA 366 southbound at Leechburg Road/Freeport Road in New Kensington* An old mast arm installation with equal number of signals for all directions.
PA 271 northbound at Woodmont Road Another 12/8/8 installation in the Johnstown area, but in a strange turn of events, there is a signal pointing into the woods.	Cambria	11/21/2004	Jeff Kitsko
PA 271 northbound at Gardner Street/Luzerne Street in Johnstown One pole with two mast arms, doing double duty for this four-way intersection and pedestal signals.
Bedford Street at Main Street/Clinton Street in Johnstown Another variation on Johnstown signals is this modern design.

Maclay Street at West Sixth Street in Harrisburg Four-way non-adjustable Eagle signal in the state capital.	Dauphin	11/28/2004	Dave Call
PA 31 westbound at Cherry Avenue in Mount Pleasant A staggered intersection with the main route having all of its signals overhead, but the side streets only one.	Westmoreland	12/7/2004	Jeff Kitsko
PA 31 westbound at PA 819 in Mount Pleasant Unique intersection that looks much like a traffic circle, but it is not.  The statue in the center is the Doughboy monument which was erected in 1924 to honor all who have served in the armed forces.
PA 31 westbound at Mullin Avenue in Mount Pleasant Further down PA 31 with a four-way signal and lone auxiliary signals for each direction on Main Street in Mount Pleasant.

PA 819 northbound at Pittsburgh Street in Scottdale Signals with eight inch indicators except the 12 inch left turn arrow.  Notice the double angled mast arm.
Pleasant Unity Signal Flashing red indicators for all directions, but originally, they were only used on the side streets and the main route had flashing yellow.  Located in Pleasant Unity on PA 130 and PA 981 South.
PA 72 northbound at PA 283 westbound When rebuilt in the late 1990s-early 2000s, the expressway system around Lancaster was rebuilt.  With that, traffic signal installations were given these stylized poles.	Lancaster	12/16/2004	Chris Daub
Plaza Boulevard at PA 72 Looks like a signal installation in southeastern Pennsylvania with the signals on poles at car level.
US 222 northbound at PA 272 and PA 568 Temporary signals being used at the beginning of the US 222 expressway construction project southwest of Reading.	Berks
Lincoln Way at Eisenhower Road in White Oak I remember when this installation was in continual flash mode, and around the mid-1980s, became fully functional.	Allegheny	12/26/2004	Jeff Kitsko
Truck US 19 northbound at Warrington Avenue in Pittsburgh The other set of signals involved in the Liberty Tunnel SPDI.  What is unusual is not only the doghouse on a pedestal, but also the use of the four head right turn signal for PA 51 northbound.	Allegheny	12/29/2004	Jeff Kitsko
Wilkes-Barre Boulevard at Scott Street in Wilkes-Barre Signals on the boulevard used to have an unusual color combination:  black fronts and visors with yellow backs.  Most were replaced except for this doghouse.	Luzerne	1/16/2005	Timothy Forbes
US 30 eastbound at Planebrook Road in Malvern Another way to put a back plate on a dog house signal, as well a favorite treatment for side streets in District 6:  a pedestal signal on the right.	Chester	1/26/2005	Andrew Fields
US 30 westbound at Darby Road in Paoli The greens are LEDs as you can tell by the pattern.	Chester	1/28/2005	Andrew Fields
US 202 southbound at Gulph Road in King of Prussia Another signal District 6 likes to install are the four indicator protected/permissive turn signals.  For the side street there is not one, but two.	Montgomery	1/30/2005	Andrew Fields
Montour Run Road at PA 60 North in Robinson Looks like an installation from southeastern Pennsylvania with that pedestal signal in the median.	Allegheny	3/6/2005	Jeff Kitsko
PA 28 northbound at the 31st Street Bridge/Rialto Street in Pittsburgh More pedestal signals on the right for Rialto Street and an all 3M indicator doghouse which is on the pole at the left side of the picture.
PA 8 northbound at Butler Plank Road in Glenshaw Unusual combination of wire-span and mast arm installation.  Note the changeable "LEFT TURN SIGNAL" sign which will go to a no left turn sign due to the train crossing on Butler Plank Road.

E-ZPass Signal Every lane at every toll plaza on the mainline Turnpike and Northeast Extension feature these signals.  Green-thank you, yellow-low balance, and red will light depending on your transaction.
Monroeville Road at Monroe Drive in Monroeville A box wire-span installation with only one signal getting a back plate.	Allegheny
Monroeville Road at Wyngate Drive in Monroeville Some sun faded signals in this installation, with a rare four head protected/permissive signal instead of a dog house.  The signal on the opposite side is an advance light for traffic coming around the curve.
Monroeville Road at Oxford Drive in Monroeville Another installation that is newer than the earlier one that also uses 12/12/12/12 protected/permissive turn signals.  Monroeville Mall, which is mentioned on the sign at the right, is where George Romero's original Dawn of the Dead was filmed.
Emergency Signal The first one of these I have seen using the current Pennsylvania standard signal installation:  yellow signals with black back plates on mast arms.  What is unique about these are that instead of being 12/8/8, they are 12/12/8.
Monroeville Road at James Street, Brinton Road, and Pindman Street in Monroeville A massive five point intersection that features both 12-12-12-12 protected/permissive turn signals, protected turn signals, and dog house signals.  Speaking of the latter, if you look at the bottom right indicator of the signal at the left, you'll see the arrow is at an angle.
Johns Street at PA 56/PA 403 in Johnstown Since no left turn is permitted onto Roosevelt Boulevard, all traffic from Johns Street must turn right.  A rare simultaneous red indicator and green arrow.	Cambria	5/31/2005	Jeff Kitsko
PA 56 eastbound/PA 403 southbound at Napoleon Street and Walnut Street in Johnstown A rare four indicator protected/permissive left turn signal in western Pennsylvania.  The arrow is angled for PA 403 traffic to continue onto Napoleon.  In the background is the Cambria County War Memorial Arena, home to the Johnstown Chiefs who were named after the team in the movie Slapshot which was filmed in Johnstown.

US 209 northbound at Business US 209 in Marshalls Creek The signal facing the right looks like the green arrow was added on, instead of being balanced evenly below the yellow.  Another instance of a pedestal doghouse signal.	Monroe	6/2/2005	Jeff Kitsko
US 209 southbound at Bushkill Falls Road in Bushkill Warning beacon at this busy intersection which leads to Bushkill Falls which is called the "Niagara Falls of Pennsylvania."	Pike

Industrial Boulevard at PA 982 in Derry* You are not seeing things, that is a yellow ball instead of a yellow arrow in the left turn signal.  The signals for PA 982 use a long tube visor I have never seen anywhere else.  This installation has been around since before I was born.  Some of the rare 1970s era signals still in use.
East 10th Avenue at Lawton Street in Tarentum These signals have taken a licking and keep on ticking.	Allegheny	8/6/2005	Jeff Kitsko
Freeport Road at Montana Avenue in Natrona Heights Another double intersection with all sizes of signals.
Freeport Road at Princeton Avenue/Heights Plaza in Natrona Heights Another installation with dueling signals, but this time using two sets for each direction on the cross street:  regular signals and 3M signals.
Freeport Road at Spring Hill Road in Natrona Heights The last double intersection along northbound Freeport Road.
Freeport Road at Highland Mall in Natrona Heights Simple three direction installation with a four indicator protected/permissive turn signal.
Freeport Road at Veteran's Lane/Oak Manor Drive in Natrona Heights Simple four-way installation with both sides getting redundant signals due to the angle of the intersection.

Bakerstown Road at Alter Road in Natrona Heights A four-way flasher installation with PA 28/Allegheny Valley Expressway in the background.
US 22 at Berlin Farm Road/Harrison City Road in Murrysville Old installation with signals with 12 inch indicators for US 22 and signals with eight inch indicators for the minor highways.	Westmoreland	8/9/2005	Jeff Kitsko
Old US 119 at American Video Glass in New Stanton A standard 1970s PennDOT installation with black stylized poles, but this assembly has been turned off due to a reconfiguration of the SONY parking lots.  It appears as though it serviced another entrance to the plant at one point.
PA 217 at Market Street in Blairsville Installation with all of the signals on poles at each corner of the intersection.	Indiana	8/11/2005	Jeff Kitsko
Market Street at Stewart Street in Blairsville Another similar installation just a block east on Market Street.

West Newton Street at South Spring Avenue in Greensburg* Rare one signal per direction set up near Westmoreland Hospital.  The main signal was removed and never replaced as attested by the vacant connector still hanging over the intersection.	Westmoreland	9/7/2005	Jeff Kitsko
Mount Pleasant Street at Highland Avenue in Greensburg Due to the angle of the intersection, the box wire span is more of a rhombus.
PA 837 southbound at Arlington Avenue in Pittsburgh A mix of horizontal and vertical signals at this intersection with four indicator protected/permissive turn signals and doghouses.  If you saw the movie Striking Distance you might recognize this intersection.	Allegheny	9/23/2005	Jeff Kitsko
Truck US 19 southbound at the South Busway in Pittsburgh An unusual installation that only controls traffic southbound to allow Port Authority buses safety onto West Liberty Avenue.  The two indicator signals facing the other direction sequence red to green.

Centre Avenue at Washington Place in Pittsburgh A "mish-mash" of different sized signals and in locations that do not offer the best visibility.  The silver dome off to the left is Mellon Arena (Civic Arena), home of the Pittsburgh Penguins and the oldest building in the NHL and the world's first with a retractable roof.
Centre Avenue at Mario Lemieux Place in Pittsburgh Another old installation at the next intersection.
West Pittsburgh Street at Bell Way in Greensburg* Here is one that wasn't replaced for whatever reason.  The single signal head facing to the left is a turn indicator that lights on the green phase, and then off after a period of time.  Bell Way coming from the left side of the picture is eastbound PA 130.  The designation turns onto West Pittsburgh Street to head east out of the city, as indicated by the PA 130 shield ahead.

PA 201 southbound at Finley Road in Allens Crossroads Mirror image angled mast arm installation with pairs of signals for perpendicular direction which is rare at the intersection where PA 981 used to cross.	Westmoreland

US 220 northbound at Milan Road in Milan Intersection control beacon with 12 inch indicators for US 220 and eight inch indicators for the side streets with the exception of the one facing left.
US 220 northbound at NY 17 in Sayre Wait a minute!  This NYSDOT signal installation is technically inside Pennsylvania, as is NY 17, but the only thing that makes it look like a product of the Keystone State is that the signals are yellow instead of NYSDOT's dark green.
US 220 northbound at NY 17 in Sayre More NYSDOT signals posing as Pennsylvania ones on the other side of the overpass, but at least these are closer to the box wire-span installations in the Keystone State.

Freeport Road at Saxonburg Boulevard in Natrona Heights Installation that features multi-way signals that are attached at the bottom and not top as usual.

PA 366 southbound at Seventh Avenue in Tarentum The other half of the intersection seen at PA 366 northbound at East Sixth Avenue.  Simple box wire-span installation with a signal-controlled slip ramp to West Seventh Street and inline four protected/permissive turn signals for both directions of Seventh Street.

Crawford Run Road at Freeport Road in Creighton No overhead signals at this old installation.	Allegheny
Freeport Road at Third Street in Creighton Unusual wire-span installation in conjunction with the railroad crossing on the left.  Several five indicator protected/permissive signals.  Ed Kalix who grew up nearby told me that the signal is connected with the train crossing.  When a train crosses, the green indicator goes off and the green arrow activates; however, the green indicator and arrow should not be lit at the same time.  A green straight arrow and right pointing arrow light up while the green indicator turns off on the signals on the pole.
