FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
'The 2 span, 196'-long, pin-connected Pratt thru truss bridge built in 1893 is supported on a stone substructure. It was fabricated by John Denithorne & Sons of Phoenixville, the details of the bridge, including the verticals, upper sway bracing, and portal bracing, reflect period thinking about truss members. Denithorne was successful marketing his bridges to Chester and Montgomery counties into the 20th century. The bridge has some alterations, but they do not adversely impact its significant details and overall integrity. It is historically and technologically significant because of its association with the Denithorne company and what that illustrates about metal truss bridges were built during the last quarter of the 19th century and for its technological significance.'
