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

The Pennsylvania Historic Bridge Inventory thinks that this abandoned bridge is common technology, and has no distinctive details. Perhaps they didn't even look at the bridge. It may be simple if you label it a 1935 Warren Pony truss with riveted connections, which is indeed what the bridge is, and if you leave the description at that, it is a rather basic bridge. However, take a look at this bridge and you will see it is anything but ordinary. For one thing, the end posts are vertical, giving the bridge the unusual rectangular appearance. Also, the built up members and chords are made of unusual plate-like designs, a design that is uncommon but sometimes found on bridges carrying or crossing over a railroad. Assuming the construction date is accurate, the bridge's design is reflective of earlier designs that the railroad companies used. The bridge retains original pipe railings. A wooden deck is present on the bridge. The bridge is supported on concrete abutments and piers.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1935, skewed, 3 span, 160'-long bridge has an 88' long riveted Warren with verticals pony truss main span and deck girder approach spans (1 @ 32', 1 @ 36') supported on concrete abutments and battered concrete columns. The heavy trusses have no innovative or distinctive details. The bridge is an example of a common technology used in the state since ca. 1890. Fourteen riveted Warren pony truss bridges dating from 1897 remain in northwest Pennsylvania. Earlier examples better represent the type and design in the state and region. This bridge is not historically or technologically significant, and the railroad is not significant in the Pennsylvania context.

Discussion of Surrounding Area

The bridge carries a 2 lane unimproved road over a single Conrail (formerly the Erie Railroad) track in a sparsely developed, wooded setting that does not have historic district potential. A second track has been removed.

Bridge Considered Historic By Survey: No
