Description

"The 3-panel riveted Warren pony truss bridge is supported on ashlar abutments which have been widened with concrete. One wingwall is stone, the others are concrete. When the bridge was widened in 1947, the entire flooring system was redone. The top chord of back-toback angles has an added welded cover plate, and welded reinforcing has been added to upper panel points. Design integrity has been compromised."
