This bridge is a less common design of Pratt truss that the Wrought Iron Bridge Company built. Over the years of its operation, the company had a variety of standard designs it used for building bridges. This bridge is an example of one of those designs, which included an a-frame portal bracing with the unusual detail of the build plaque being fitted into the frame.
In addition to its significance as a surviving example of one of the less common designs of a noteworthy bridge builder, this bridge is also significant for having a skew to it, something not commonly found with the older pin connected bridges. The skew is very slight but is noticeable. Original railings do not remain on the bridge. There is v-lacing on the verticals and under the top chord/end post.
The Historic Bridge Inventory mistakenly lists the rail line south of the bridge. The line appears to be active, and it listed as an Oil Creek and Titusville Railroad line. The four-pronged connection detail they mention is the bottom of the hip verticals.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 1889, pin connected, single span, 120'-long, Pratt thru truss bridge is supported on ashlar abutments with wingwalls. Verticals, end posts, and upper chords are built up. Lower chords and diagonals are eye bar. The bridge was built by the Wrought Iron Bridge Company, a prominent fabricator of metal truss bridges, and it has the company's distinctive hip verticals with four pronged connection details at the lower chord panel points. The bridge is historically and technologically significant as a complete, early example of its type and design.
Discussion of Surrounding Area
The bridge carries 1 lane of a 2 lane unimproved road over a stream in a sparsely developed agricultural setting. There are trees at all quadrants. A single abandoned Conrail (formerly Erie Railroad) track crosses the road at grade just to the south of the bridge. The farms in the area are undistinguished and vernacular, and do not have historic district potential.
