History: | Proposed spur from I-78, which at the time was on the Lehigh Valley Thruway, from 1962 to 1971. The northern terminus would have been between the 15th Street and PA 145 interchanges. The reason for its cancellation was because the Liberty Bell Shrine was in the path of the proposed expressway, and NIMBYs protested the destruction of Sixth and Seventh Streets. | |

History: | This
designation's length and location bounced around Pennsylvania over the
span of a decade. From 1957 to 1958, the route would start at
Carlisle and head east to King of Prussia, then south to Philadelphia via
the Schuylkill Expressway.
From 1958 to 1960 the route was changed in eastern Pennsylvania to follow the Pennsylvania Turnpike all the way to New Jersey. Then in 1963, the route was moved back onto the Schuylkill Expressway and then turned onto the Vine Street Expressway to head into New Jersey. Then 1964 to 1972, this designation was used for the section of the Pennsylvania Turnpike from the Ohio state line to Pittsburgh Interchange. |

History: |
Proposed in 1964 and originally planned to start at I-95 south of Ridley Park, then in 1967 changed to start at I-95 at the Philadelphia International Airport, the expressway would connect to Interstate 76 at Federal Street in downtown Philadelphia. There was talk of it continuing eastward along South Street and being known as the Crosstown Expressway, which would have ended at Interstate 95. Hearings were held throughout the 1960s and 1970s. It was feared that it would create a "wall" between the wealthy areas such as Center City, Rittenhouse Square, and Society Hill to the North, and South Philadelphia. For several years, the Crosstown Expressway was listed on the Philadelphia City budget under "controversial proposals" with no monetary value. The Crosstown Expressway was cancelled in 1974, and removed from the PennDOT map that same year, due to the local opposition, and the Cobbs Creek Expressway was cancelled in 1977 due to PennDOT funding difficulties. The Federal money for the project was diverted to bus purchases and subway rehabilitation. | |

History: | From 1958 to 1960, this designation was used to mark the Vine Street Expressway. In 1970 the designation was moved to a proposed expressway which would have begun at Interstate 95, crossed the Delaware River, and connected to I-295 and to the New Jersey Turnpike in Burlington County, New Jersey. The six-lane expressway, and new high-level, fixed-span toll bridge, would have replaced the current Burlington-Bristol Bridge. This Interstate would have provided a bypass for travelers to avoid the traffic in downtown Philadelphia. The last map to show this Interstate was in 1977. The project was officially cancelled in 1980 when the Environmental Impact Study prepared by PennDOT was denied. | |
