Back Creek Bridge
Share: 
Description
FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 2-span, 110'-long, steel stringer bridge has metal angle and channel railings, open grid steel deck, rolled steel beam stringers with welded angle crossbracing, and stone pier and abutments with wingwalls. Built in 1938, it has no innovative or distinguishing details and is an example of the most common, mid-20th century bridge type in the state. The bridge was built using a standard design developed by the state highway department in the early 1930s. Neither the bridge nor its setting or context are historically or technologically noteworthy.Facts
