from the PennDOT Historic Bridges Survey:
"The bridge carries a 4 lane highway and 2 sidewalks over a stream and local road on the north bank of the Ohio River in a setting dominated by modern, franchise commercial development. It was built as part of the Ohio River Boulevard, the highway designed to speed traffic to the McKees Rocks bridge. The highway has lost integrity due to alterations to its original geometry and roadside features as well as extensive modern development along it. Neither the highway nor the setting have historic district potential.
The 1930, 307'-long, reinforced concrete, ribbed, open spandrel deck arch has a 150'-long main span and slab approach spans supported on concrete abutments and concrete column and cap bents. In 1980 the bridge was widened by the removal of the original cantilevered deck sections and balustrades and placement of wider cantilevered deck sections with plain bracketed supports and safety shape barriers at the roadway curbs. Four spandrel columns were also replaced. The sidewalks are finished with chain link fence pedestrian barriers. Most of the columns have been shotcreted. Neither the bridge nor its setting and context are historically or technologically significant due to extensive alterations."
