This bridge is a good unaltered example of a Queenpost pony truss. Southwestern Pennsylvania has (or had) an unusually large number of Queenpost pony truss bridges, which are usually a rare bridge type. Of the several that could be found in this region, this particular bridge stands out for its lack of alteration. The bridge has been closed to traffic, and a rather crude method of barricading the bridge was employed, where the timber deck was pulled up and stood up at each end of the bridge.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 44' long and 12' wide, light, riveted Pratt pony truss built in 1902 is supported on ashlar abutments with wingwalls. The bridge has no innovative or distinctive details, and although it appears to be complete, it is an example of the standardizations of metal truss bridges that occurred by the late 19th century. The field connections are both bolts and rivets. Riveted field connections in Pennsylvania date to at least the late 19th century. Neither the bridge nor its setting are historically or technologically significant. There are over 25 metal truss bridges from 1887 through 1935 in Washington County. There are also many early 1900s Nelson & Buchanan pony truss bridges in the county.
Discussion of Surrounding Area
The bridge carries one lane of a two-lane road over a stream in a sparsely developed, wooded setting with some trailers. The area does not appear to be a potential historic district.
