This bridge is a late example of a bridge fabricated by the Penn Bridge Company. The Penn Bridge Company built many bridges in the late 1800s that still remain in Pennsylvania. This 1929 bridge represents the work the company was doing long after bridge standardization had taken root. This traditional riveted pony truss bridge however does have one unusual detail, which is the concrete posts that extend from the abutments and connect to the main truss via a section of steel. These appear to have been placed mainly for decorative and protective purposes. They are not structural.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The one-span, 44'-long, riveted, Warren with verticals pony truss bridge built in 1929 is supported on concrete abutments with wingwalls. The floor beams are located above the lower chord. The trusses are traditionally composed with built up members throughout, and a channel traffic railing has been placed inside the truss lines. They connect to concrete end posts placed at the backwall of the abutments. There are minor bolted repairs. The bridge is a late 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 single-lane road over a stream in a sparsely developed, rural area with scattered 20th century residences.
