Route 8 Expressway
The expressway was proposed to begin at an interchange with the Penn-Lincoln Parkway East and Route 30 Relocation near the current Edgewood/Swissvale interchange. It would have continued north through Frick Park and East Liberty to Negley Run Boulevard. From that point, it would have supplanted Washington Boulevard to the Allegheny River and crossed the river in the vicinity of the Pittsburgh Zoo/PPG Aquarium east of the Highland Park Bridge. Continuing northwest, there would have had an interchange with the East Street Valley Expressway before turning back northeast to the Butler Valley interchange on the Turnpike where it would have ended. A feasibility study was completed in the early 1960s on the alignment, and was projected to be 55% completed by September 10, 1964. Interchanges would have been constructed at the following locations:
