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

This bridge is very unusual because its truss members are extremely lightweight in design. The bridge has an unbelievably delicate appearance. Travelers need not worry about this however, since a steel bent was added under one of the floor beams, so the truss is not bearing a full load anymore. The bridge is a little mystery. The unusual lightweight design makes it hard to date. The historic bridge inventory guess-dated it to ca. 1910. Indeed, lightweight truss bridges were sometimes built around this time. The National Bridge Inventory gives an 1893 construction date. If this were accurate, it would make the bridge an early example of a rivet-connected truss bridge.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 54' long and 14' wide riveted Warren with verticals pony truss bridge is supported on ashlar abutments with wingwalls. All members of the trusses are composed of angles, and some of the field connections are bolted, and the outriggers are original. In 1995 the truss was strengthened by welding pieces of steel plate to the bottom chord at the abutments. New steel sliding plate bearings were also added. The floorbeams and stringers were also replaced, as was the timber deck. The bridge was also underpinned. Neither the altered bridge nor its setting are historically or technologically significant. It dates stylistically to ca. 1910.

Discussion of Surrounding Area

The bridge carries 1 lane of an unimproved township road over a stream in a rural area with scattered modern houses. The area does not appear to have historic district potential.

Bridge Considered Historic By Survey: No
