Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: 'The single span, 114'-long and 17'-wide, pin connected, Pratt thru truss bridge is traditionally composed with the built up box section upper chords and inclined end posts using X pattern bars instead of the lacing. The verticals are angles with a laced web, and the diagonals and lower chords are eye bars. In 1981 the bridge has been strengthened by welding additional members. It is attributed to John Denithorne based on the design of the built up box section upper chords and end posts and sizes of the eye bars. Denithorne was a prolific builder of metal truss bridges in the region, and there are several complete and earlier examples of his work in Montgomery County, including 46 7046 0620 0059. This example is later, does not have any innovative or distinctive details, and has been altered with additional members welded to it. It is not historically or technologically significant because of its alterations.'
