Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 2-span, 112'-long and 25.3'-wide stone arch bridge has rubble-coursed field stone spandrel walls and parapets with concrete capstones that continue across the wingwalls. The spandrel walls exhibit movement. The voussoirs of the arch rings are partially parged. The intrados are parged, and toe walls have been placed. It is a late and undistinguished example of its technology, and it is not historically or technologically significant. Montgomery County has a rich assemblage of 50 stone arch bridges dating from 1789 to 1919, and many of the examples are significant.
