There were two truss bridges on this road that crossed a river by way of an island. Both were demolished and replaced with a slab.
FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
The single span, 113'-long, pin-connected metal Pratt thru truss bridge built in 1889 is supported on stone abutments. The truss is composed of built-up compression members and eye bar tension members. It has double-looped floorbeam hangers in the end panels, a trademark of Wrought Iron Bridge Co. bridges. Rolled section floorbeams carry steel stringers and an open steel grid deck placed in 1969. Earlier railings have been lost and replaced by W-beam guide railings. The bridge is a historically and technologically significant example of its type/design by an important late-19th-century fabricator. The Wrought Iron Bridge Co. was among the best known and most successful bridge fabricators to market and popularize the pin-connected truss designs for highway applications.
