This quaint little bridge is so small that the railings are as high as the top chord! With a 1919 construction date one might be surprised to see such a small warren pony truss with riveted connections being listed with a high level of historic significance. However this is one of the first bridges to use rolled H section beams for a top chord and end post. As such the bridge is quite historic since it anticipates, well ahead of time, the transition away from built-up beams and rolled American Standard Beam style i-beams.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 52' long and 13' wide Warren pony truss bridge dated 1919 is supported on one concrete abutment with wingwalls and one ashlar abutment. The top chords and inclined end posts are rolled H section. All other members are traditionally composed. A two rail high steel channel railing has been attached to the bridge and finished with squared ends that extend beyond the end posts. The bridge is historically and technologically significant as one of the earliest if not the earliest documented application of the rolled H section for compression members, and it is a technologically significant. There are apparently no original plans for the bridge.
Discussion of Surrounding Area
The bridge carries one lane of a township road over a stream. Southwest of the bridge is a large gravel pile from a stone crushing plant. North are scrub woods and fields. The area does not appear to have historic district potential.
