Over the spring, I received a few new leads on the history of the unbuilt PA 48 freeway east of Pittsburgh. This included the first to my knowledge diagramed schematics of the Lincoln Way and Jacks Run/Center Road interchanges in White Oak Borough.
Much of the new information comes from a 1972 Environmental Impact Statement on the highway near McKeesport done by PennDOT.
Further detail on the plans to build the highway - the middle section from the Youghiogheny River to Pitcarin/Trafford Area was to be built first. Right-of-way acquisition for over 100 homes and 26 businesses was underway. An interchange at McClintock Road near White Oak County Park was removed.
From the drawings (shown from a different project) the White Oak interchange at Lincoln Way would not have been a cloverleaf.
The Northern Section - Pitcarin/Trafford to US 22 in Monroeville was under corridor selection.
It is suggested that the northern terminus of the freeway would have been about a mile east of the Pittsburgh Interchange (I-376/US 22) near where the former Burke Glen Park (now Levin Furniture and Sheetz).
The Southern Section from the Youghiogheny River to PA 51 in Southeastern Allegheny Count would be built last. Preliminary engineering was just started, as of 1972. It was estimated that roughly 100 homes would be taken in this section. With an estimated 80 homes being purchased in the Elizabeth Township Community of Boston.
(On a personal note - I grew up in Elizabeth Township, PA and this would have devastated the town of Boston along the Yough River.)
Link to the updated feature is below - and as always any new information or leads are welcomed.
