Bridge Status: Demolished and replaced.

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is an excellent representative example of its type in Pennsylvania. The bridge appears to be complete including original plaques.

This bridge has been found not historic by the Historic Bridge Inventory. However, this assessment is outdated. For example, it does not reflect the demolition of other similar bridges in the area and even within this county. The bridge is a relatively early example of a truss bridge with riveted connections, and it retains excellent historic integrity. Bridges like this are disappearing from Pennsylvania's landscape, a fact highlighted by the reality that this bridge itself is slated for demolition and replacement.

Although this bridge does show deterioration in the form of section loss on the floorbeams and deck stringers, these are elements often replaced during a rehabilitation. It appears that a rehabilitation project could be developed for this bridge in place of a demolition and replacement project. If however plans to demolish this bridge remain, HistoricBridges.org suggests salvaging the trusses and placing them on the replacement bridge as a decoration, which would retain some of the original bridge and its appearance.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The single span, 108'-long, rivet-connected Warren with verticals pony truss bridge built between 1907 and 1911 is supported on stone abutments. The 10 panel truss has built-up members of standard steel sections. Rolled floorbeams and stringers support a timber deck. Stock lattice railings are set to the interior faces of the trusses. The Warren truss type/design, patented in 1848, emerged as one of the most commonly used truss designs after 1895 because of advances in metallurgy and improvements in field pneumatic riveting. Over 125 examples from the late 1870s to 1950s have been identified in the state. This 1907-11 example has no noteworthy or unusual features or details. It is not an early or significant example of the work of the Penn Bridge Co., which was very active in the eastern United States from the 1870s to 1930s. Nor is it significant for its historic association with the 1895 state bridge act, a relatively ineffective law that provided funding for rebuilding county-owned bridges from 1895 to 1923. The bridge is not historically or technologically distinguished by its setting or context.

Discussion of Surrounding Area

The single lane bridge carries an unimproved road over a stream in a rural setting of woods and scattered late 20th century houses. All of the immediate quadrants are wooded. The setting does not appear to have historic district potential.
