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

This striking bridge represents a perfect example of a classic pony truss. Retaining excellent historic integrity, it conveys a sense of what a common bridge in the late 19th Century might have been like. Today however, the bridge is distinguished as a good example of what was. It is today a rare, and beautiful structure. Featuring v-lacing on the verticals, this is a pin connected structure. The bridge is composed of five panels. Original pole railings remain on the bridge. The deck is wood. The built-up fishbelly floorbeams are an attractive design, and offer a lot more to look at for those who take a peek under the bridge. The structure has rusted, but is in otherwise decent shape. Now would be a great time to restore this bridge so it can continue to beautify the surrounding area, and provide a historic crossing for an additional century. The bridge's trusses are nearly identical to the Marsh Road Bridge which was associated with the Penn Bridge Company. It is thus assumed that the Penn Bridge Company built this bridge as well. Both bridges have an unusual bottom chord connection detail at the hip vertical which includes a threaded rod and nut above the floor beam (separate of the u-bolt). The Marsh Road Bridge lacks the built-up fishbelly floor beams, but this is likely because the more rural Marsh Road Bridge has a narrower roadway width which would have only needed shallower rolled i-beam floor beams.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1889, pin connected, single span, 78'-long, Pratt pony truss bridge is supported on ashlar abutments with wingwalls. The trusses are traditionally composed. The built up shaped floorbeams are original. Crawford County is rich in pin connected metal truss bridges with 35 ranging in date from 1870 through the early 20th century remaining. This bridge stands out as a complete, early example of its type and design. It is historically and technologically significant.

Discussion of Surrounding Area

The bridge carries 1 lane of an unimproved road over a stream in a rural area. Approximately 500' east the road is crossed at grade by a single Bessemer & Lake Erie railroad track. The widely scattered vernacular houses, most dating from the early 20th century, are undistinguished. The area does not have historic district potential.

Bridge Considered Historic By Survey: Yes
