from the PennDOT Historic Bridges Survey:
"The bridge carries a 4 lane highway and 2 sidewalks over a local road on the north bank of the Ohio River in a setting dominated by modern, franchise commercial development and scattered, earlier houses. 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, single span, 44'-long steel stringer bridge is county standard designed steel railings is supported on concrete abutments with wingwalls. The bridge is an example of the most common 20th century bridge type in the state. Neither the bridge nor its setting and context are historically or technologically significant due to extensive alterations. What was conceived of in the late 1920s as a modern, high-speed motor highway with grade crossings eliminated is now a roadway lined with franchise commercial development and altered roadway geometry and features."
