Bridge Documentation

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

This bridge is a small Parker pony truss. It is composed of a built-up top chord that is a channel made of two angles and plate. There were once a number of similar bridges in southwestern Pennsylvania, now just a couple remain. The Penn Bridge Company was noted as the builder for one of these bridges, and it is assumed that they built the other bridges with similar details including this bridge. This bridge sits on stone abutments. A large crack runs nearly the entire height of the abutment at one corner, indicating a substructure problem. The truss itself however is in good condition, and could be rehabilitated and reused on top of repaired or replaced abutments.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1919, 54' long and 16.4' wide, riveted Parker pony truss is supported on one ashlar abutment and one lower rubble masonry abutment. The top chords and inclined end posts are built up box sections, and the lower chords, verticals, and diagonals are channels with battens. Lattice railings are inside the truss lines. The field connections are bolted, a common period detail for truss bridges like this example. The bridge has no innovative or distinctive details. Neither the bridge nor its setting are historically or technologically significant.

Discussion of Surrounding Area

The bridge carries 1 lane of a township road over a stream in a rural area of active farms. TR 332 provides access to a farm, and the road runs dead at the farm. Beyond the northwest quadrant is a heavily altered vernacular 20th century farmhouse now sheathed with vinyl siding and with the window openings altered. The area does not have historic district potential.

Bridge Considered Historic By Survey: Yes
