Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge was dismissed by the Historic Bridge Inventory, but HistoricBridges.org believes the bridge is more significant than the inventory gave it credit for. The bridge has plaques indicating it was a project sponsored by the Public Works Administration. Bridges associated with the PWA are associated with a significance event in U.S. history. Further, the bridge retains good historic integrity including original ornamental railings. The bridge acts as a grade separation for two roads that are not limited access highways, but were busy roads built in the 1930s to connect different parts of the Pittsburgh area, in particular the airport. The bridge is part of an interchange that was created for these two roads. The cloverleaf interchange ramps retain integrity of design. Together, the ramps and bridge are noteworthy as an unaltered example of an early interchange.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The bridge carries a 4 lane road with a mountable barrier and sidewalks over a 4 lane, median divided road. The bridge is part of a cloverleaf interchange that separates the grade crossing of 2 local streets. The area, a mix of post-WW II apartment buildings and residences and late 20th century commercial strip development, does not have historic district potential.

Discussion of Surrounding Area

The 1939, single span, 72'-long, reinforced concrete, rigid frame bridge has concrete wingwalls. Moderne-style pilasters at the abutments and the ends of the wingwalls rise above the deck level and serve as posts for the period steel railing with a fleur-de-lis pattern. Built to improve a congested intersection, the bridge is not technologically distinctive. Rigid frame bridges were introduced in this country in the late 1920s and were common by the late 1930s. Excluding the turnpike bridges, this bridge is one of 80 of its type in the state and one of 35 in Allegheny County.

Bridge Considered Historic By Survey: No
