Bridge Documentation

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

This is a small steel stringer bridge that features concrete encased stringers. Combined with concrete railing, this looks like an all-concrete bridge. The only architectural detailing is the rectangle outlines on the inside of the solid parapets. No detailing is present on the outside of the bridge, indicating that having a nice looking bridge here was only of interest to those driving over the bridge. Given the rural agricultural location of the bridge this is perhaps not suprising.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The single span, 27'-long, encased steel stringer bridge is supported on concrete abutments and has concrete parapets. The beams are encased down to the exposed bottom flanges of the I-shaped beams. Concrete encasement was favored in the state because it provided protection for the steel and eliminated the need to periodically paint the beams. A representative example of one of the most common, early-to-mid-20th century bridge types and designs in the state, it has no innovative or distinguishing details. It is one of 639

Discussion of Surrounding Area

The bridge carries a 2 lane road over a stream in a rural area of active farms and scattered late-20th century residences. The setting does not appear to have historic district potential.

Bridge Considered Historic By Survey: No
