Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: "The bridge carries a 2 lane road and 1 sidewalk over the West Branch of the Susquehanna River at the intersection of SR 970 and SR 879. Crossing the river just west of the bridge is a Conrail (former NY Central) deck girder bridge. A large power plant is at the southwest quadrant. At the east quadrants are a convenience store and a vacant lot The modern setting does not have historic district potential. The 1937, skewed, 2 span, 340'-long, rivet-connected Pratt thru truss bridge is supported on concrete abutments with flared wingwalls and a concrete pier. The upper chords, lower chords, and verticals in the end panels are built up. The diagonals and other verticals are rolled I sections. It is an undistinguished example of a state highway department standard design, rivet-connected truss bridges that were used with great frequency beginning in the 1920s. It has no innovative or distinctive details, and it is not historically or technologically distinguished by its setting or context. More than 350 Pratt truss bridges from the 1870s to the 1950s have been identified, with approximately 140 of that number standardized examples from after 1925."
