Bridge Documentation

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

This bridge proves that as late as 1940, bridge design in Pennsylvania was still something visually respectable, and produced bridges that were not only functional, but had aesthetic value as well. This bridge also proves that the larger, newer massive-member truss bridges can still blend in well in a wooded environment. Even with massive members, the bridge still has a delicate appearance to it, and its complex network of trusses compliments the branches of the many trees around it.

There is a memorial plaque near this bridge that says that two firefighters died while on-route to a call for help. It should be noted that apparently the bridge was not involved with or a factor in causing these deaths.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 1940 skewed, one-span, 190'-long, riveted Pratt through truss bridge is supported on concrete abutments with wingwalls. The trusses are traditionally composed with rolled section web members, and there are no innovative or distinctive details. The original lattice traffic railings remain in place. The bridge is a late example of its type and design, and neither the bridge nor its setting are historically or technologically significant.

Discussion of Surrounding Area

The bridge carries a two-lane road with shoulders over Slippery Rock Creek in a sparsely developed, wooded setting.

Bridge Considered Historic By Survey: No
