This four panel truss bridge has relatively tall trusses. It appears to retain good historic integrity. There are unusual, decorative rivets on the center of the original lattice railings which remain on the bridge. It would be interesting to know if this unusual detail was something a particular bridge company might have been in the practice of using. The truss bridge features four panels. The deck is wooden. It is an attractive structure on a quiet rural road, and their is no reason why this bridge should not continue to be maintained and be preserved for future generations to enjoy.
The NBI gave a 1910 date for this bridge. This date appears to be incorrect (too new for this design), which the Historic Bridge Inventory also seemed to agree with it, instead assigning a c. 1895 date for the bridge.
The finding of the Historic Bridge Inventory that the bridge should not be eligible for the National Register of Historic Places should be considered an outdated assessment. The staggering rate of truss bridge demolition, including in Crawford County is rapidly making bridges like this increasingly rare. Additionally, this bridge has a decent span length for its type, and is largely unaltered. These characteristics set it far ahead of other truss bridges that the Historic Bridge Inventory also found ineligible.
Information and Findings From Pennsylvania's Historic Bridge InventoryDiscussion of Bridge The ca. 1895, pin connected, single span, 72'-long, Pratt pony truss bridge is supported on one concrete and one ashlar abutment. 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 an unimproved road over a stream in a rural area of active farms and undistinguished mid and late 20th century residences. The setting does not have historic district potential. Bridge Considered Historic By Survey: No |
