FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
The one span, 130' long, pin connected Pratt thru truss bridge is supported on a concrete abutment on the west side and an ashlar abutment on the east side. The bridge plaque documented in the district survey has been lost, but the bridge is recorded as having been built by the Long Bridge Co., which is not listed in Darnell's directory of pre-1901 fabricators. The bridge is traditionally composed. The verticals are toe-in channels with lacing, and the floorbeams are suspended from the lower panel point, but welded straps have been added to augment the connection. The knee braces of the lattice portal brace have punchwork decoration. The bridge is a late example of its type and design, and it has some alterations. It is located in a region noted for its many and complete early pin connected bridges. In comparison with the regional population, this bridge is not historically or technologically significant.
