This bridge is unusual because it was built in the 1930s but does not follow the standard plan for truss bridges seen in Pennsylvania. The Pennsylvania Historic Bridge Inventory incorrectly reports that this bridge has built-up end posts and top chord. In fact, the entire bridge's trusses are composed of rolled beams, which is what makes the bridge unusual both in appearance and design. The bridge has two Parker through truss spans, a full-slope Pratt pony truss approach span, and a steel stringer approach span.
The bridge appears in the movie Promise Land and can be seen in this trailer.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The bridge built in 1937 consists of 2, 215' long, riveted, Parker thru truss spans and a 91' long Pratt pony truss approach span on the south end and 41' long stringer span at the north approach. The main span trusses have built up upper chords and end posts, but the web members are all composed of rolled section. The trusses have no innovative or distinctive details. The cantilevered sidewalk is finished with metal railings. Neither the bridge nor its setting are historically or technologically significant. Many original rivets have been replaced with high-strength bolts.
Discussion of Surrounding Area
The bridge carries a 2 lane road and 1 sidewalk over the Kiskiminetas River at the Westmoreland-Armstrong county line. The north side of the bridge is wooded. The south side in Westmoreland County is a mix of altered and undistinguished early through late 20th century houses. The setting does not appear to have historic district potential.
