Bridge Documentation

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

This rather old bridge is a five panel full slope Pratt pony truss bridge, and was built by the Morse Bridge Company. Like other bridges the company built such as Michigan's Six Mile Creek Road Bridge, this pony truss features the unusual detail of cast iron washers on the ends of the pins. Some of these nuts on the Jerusalem Road Bridge have been replaced, but others still remain on the bridge. These nuts were an interesting design, but they appear to be cast iron, typical of the metal, brittle, and they seem prone to breaking (see again, the Six Mile Creek Road Bridge), which probably accounts for them being replaced on the Jerusalem Road Bridge. Very few examples of this company's work remain in existence. Surviving example's of their work are significant, including this bridge.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1884, pin connected, single span, 68'-long, Pratt pony truss bridge is supported on ashlar abutments. The traditionally composed trusses have metal rod diagonals and hip verticals, built up upper chords and verticals, and eye bar diagonals. The beam guiderails were added ca. 1990. Crawford County is rich in pin connected, metal truss bridges. A total of 35 ranging in date from 1870 through the early 20th century remain in the county. This bridge stands out as an early, complete, documented example of a pin connected Pratt pony truss bridge. Adding to its significance is its documentation to the Morse Bridge Company, a short-lived but prolific regional bridge fabricator. The bridge is historically and technologically significant.

Discussion of Surrounding Area

The bridge carries a 1 lane of an unimproved road over a stream in a sparsely developed, wooded setting with widely scattered residences, mostly modular homes from the late 20th century. The area does not have historic district potential.
