History: Signed in 1946 and in 1948, the southern terminus was moved from Banksville Road to its current location.

In 1982, a northern disconnected section was signed from US 19 at the northern end of the West End Bridge to Wexford.  The designation followed Western Avenue, West Ohio Street, circled Allegheny Center on the Commons, East Ohio Street, East Street, and McKnight Road.

In 1984, the alignment was changed with northbound traffic using Western Avenue, Allegheny Avenue, North Shore Drive, General Robinson Street, Anderson Street, River Avenue, and Voeghtly Street.  Southbound traffic was moved to Reedsdale Street and Beaver Avenue.  In 1989, the designation was moved onto I-279 to form a complete Truck US 19 from Mount Lebanon to Wexford after the Parkway North was completed.

Construction began in 1997 on the interchange at the southern portal of the Liberty Tunnel which was completed on November 20, 1999.

With a long history of dangerous driving conditions along West Liberty Avenue, an improvement project began in July 2010.  The road was resurfaced, first from McFarland Road in Dormont to Wenzell Avenue and Brookline Boulevard.  Old asphalt was milled and repairs made to the concrete base, broken curbing was fixed, and traffic and pedestrian signals were updated and retimed, and the roadway was restriped for four lanes of travel.  The second phase of work, from Wenzell Avenue to the South Busway started in Spring 2011 due to gas line replacement work the year before.  Complicating the project was the excavating of a 22-foot-wide strip in the center of the street to remove the old streetcar rails that were buried beneath the pavement.  West Liberty Avenue was restriped from Wenzell Avenue north to Saw Mill Run Boulevard from two wide lanes and a center turn lane, to two narrow lanes, as one resident noted, in both directions and the center turn lane.  The $7.3 million project concluded in Fall 2011, and about a year later, won an ASHE (American Society of Highway Engineers) Pittsburgh Section Outstanding Highway Engineering Award.

Driving became hazardous the night of February 21, 2011 when eight inches of snow fell in the Pittsburgh area.  About a dozen vehicles became stranded on the ramp from Interstate 279 to McKnight Road, prompting PennDOT to close it until plow trucks could come out to salt the roadway.  The drivers who had to abandon their vehicles returned the following day to retrieve them.
