Stoney Creek Bridge



FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 1-lane bridge carries a 2 lane road over a stream in a rural area with scattered 19th and 20th century residences. The setting does not have the cohesiveness or integrity of a historic district.

The one-span, 53'-long, steel Pratt pony truss bridge built ca. 1910 is supported on concrete abutments. It is composed of built-up members of standard steel sections. Rolled floorbeams and stringers carry an open steel grid deck. Bolts have replaced rivets at the upper and lower chord connections at an unknown date. They are an indication that the truss has probably been relocated. The fabricator and date of construction/alteration are not documented by available state or county records. The bridge is an altered and undistinguished example of the rivet-connected Pratt truss type/design that was common in Pennsylvania beginning in the late 1890s. Over 375 Pratt truss bridges from 1870 to 1956 have been identified by the survey. This example is not historically or technologically significant for its setting or context.
