Bridge Documentation

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

This bridge has a fixed pin-connected Parker through truss span, a rivet-connected Warren pony truss bascule span that no longer functions and has its counterweight removed, and finally concrete t-beam spans at each end of the bridge. The bascule span appears to have been a Strauss overhead counterweight trunnion bascule bridge. With its counterweight removed, the pony truss bascule span does not visually look like the main span, and the large pin-connected Parker truss span stands out as the visually dominant span on the bridge today.
