There are a few bridges in northwestern Pennsylvania that have been retrofitted with steel beams. There are pros and cons to this. Perhaps these beams, which add load-bearing strength to the bridge, do serve to help keep the bridge open to traffic longer, but they do not address the need for rehabilitation of the historic truss, allowing the truss to continue to deteriorate. The beams are large rolled i-beams set on top of the deck. There are holes in the top and bottom of the beam that a hanger goes through. You can see the hanger in the above photo to the left of the original hanger under the bridge. Essentially, the added beam and the original truss bridge's floor beams combine to work like a through plate girder. Also, the big beams do tend to visually obstruct the view of the attractive historic trusses. Solutions like this should be considered short term. A well-planned rehabilitation can bring the bridge back to like-new condition without the beams and can be cost-effective.
This little pony truss is noteworthy for its v-laced railings that you have to look behind the beam to find. Railings are usually lattice, although they do sometimes show up v-laced instead. The bridge itself is a half-hip Pratt that is composed of three panels.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The pin connected, single span, 41'-long, Pratt pony truss bridge built ca. 1895 is supported on ashlar abutments with flared wingwalls. The traditionally composed trusses have no innovative or distinctive details. The upper chords and end posts are built up, the lower chords and diagonals are eye bars to facilitate the pinned field connections, and the verticals are laced angles. The fabricator and construction date are not documented in available records. The bridge is one of several nearly identical ca. 1895 pony truss bridges in the county. Sixteen pin connected Pratt pony truss bridges remain in the county with the earliest dating to 1889. It is the early examples and those with distinctive details that represent the significance and development of the technology. This bridge is not historically or technologically significant.
Discussion of Surrounding Area
The bridge carries 1 lane of a road over a stream in a sparsely developed, wooded setting that does not have historic district potential.
