This is a concrete arch bridge that is the oldest surviving bridge built by a known engineer in the county. It retains good historic integrity with no major alterations, although structurally the arch ring is severely spalling on one side, to the point where a whole section of rebar network is completely hanging out in the air.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 60'-long and 39' wide reinforced concrete deck arch bridge has paneled concrete parapets and plain spandrel walls. The arch ring is defined by projecting slightly beyond the plain of the spandrel walls. It is one of a series of concrete arch bridges in Washington County designed by the Chaney & Armstrong Engineers, later Chaney Engineering Company, in the 1910s through early 1920s. The bridge is an example of what by 1910 was common technology, and neither the bridge nor its setting are historically or technologically significant.
Discussion of Surrounding Area
The bridge carries a two-lane road with sidewalks over a stream in an area dominated by a mix of mid-19th to late-20th century residential and commercial development in the borough of Houston. Interspersed among the altered early-20th century houses are a cinder block building factory and car lot beyond the north end of the bridge, and a parking lot and chain restaurant to the south. The area does not appear to have consistency to be a potential historic district.
Bridge Considered Historic By Survey: No, Later Revised To Yes. Reason: Oldest surviving example in the county by a known engineer
