This is a small three panel half-hip Pratt pony truss with pinned connections. The bridge retains original lattice railings. The deck is wood. The vertical members are latticed, and v-lacing is under the top chord / end post. The bridge has some attractive curved elements at the end of the railings, although some of these have been damaged. The bridge is near a small hill and I was able to get some cool elevated shots of this bridge.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The ca. 1900, pin connected, single span, 47'-long, Pratt pony truss bridge is supported on one concrete capped masonry abutment and one concrete abutment. The lower chords and floor beams are connected at the panel points with pin plates, a detail marking transition from pinned to field riveted connections. The trusses are significantly altered. New pin plates have been welded at the upper panel points and new coverplate was welded to the end posts. The bridge is an altered example of what in the county and region is a common and well represented bridge type and design. The altered bridge is not historically and technologically significant. Discussion of Surrounding Area The bridge carries 1 lane of a road over a stream in a sparsely developed, rural area with scattered, undistinguished mid and late 20th century residences. The setting does not have historic district potential. Bridge Considered Historic By Survey: No |
