Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is not an early example of a cantilever through truss bridge. However so many older cantilever truss bridges have been demolished, but in Pennsylvania and nationwide, that younger bridges like this one are increasingly rare examples of their type and should be considered for historic significance.

This riveted cantilever truss bridge enjoys a distinctive visual appearance, conveyed to bridge users in the form of a heavy, imposing portal bracing, which contrasts with the much lighter and open-looking sway bracing within the bridge. The bridge's central truss span has very short cantilever arms (only three panels), making the suspended span unusually long, occupying the majority of the central span with its fourteen panels.

Overall, the bridge trusses appear to retain good historic integrity with no major alterations.

The bridge includes a full size sidewalk, but the sidewalk is within the truss lines, not cantilevered on the outside.
