Bridge Documentation

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

This is a beautiful little bridge tucked back on a rural road. It retains pipe railing, which may not be as visually attractive as lattice railings, but seem to be less common. Many bridges that once had pole railings may have had them removed. In some cases, the pipe uses as bridge railing was "gas pipe" that the bridge builder ordered and adapted for use a a bridge railing.

This bridge is important because it retains its historic integrity and is a good example of a pony truss built by the Penn Bridge Company, which operated out of a very small shop in Beaver Falls, Pennsylvania yet managed to build a surprising number of bridges in the region. A builder plaque is on the bridge, but is attached strangely since it is wider than the end post it is mounted and and as such extends beyond the end post on one side. Perhaps it was the only size plaque the Penn Bridge Company had on hand when the bridge was built, but it is unusual.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1890, pin connected, single span, 74'-long, Pratt pony truss bridge is supported on ashlar abutments with wingwalls. It is traditionally composed with built up upper chords, eye bar diagonals and lower chords, and back-to-back angles with laced web verticals. The bridge, one of three in the county fabricated by the Penn Bridge Company or its predecessor, stands out as an early, complete, and documented example of its type and design. It is historically and technologically significant.

Discussion of Surrounding Area

The bridge carries 1 lane of a 2 lane road over a stream in an agricultural area that lacks the cohesiveness of a potential historic district.

Bridge Considered Historic By Survey: Yes
