Bridge Documentation

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

With a 1951 construction date, this bridge is a late example of its type, a Strauss type heel-trunnion bascule bridge. Other than a greater number of truss members composed of rolled beams as opposed to built-up beams however, the bridge is not much different in appearance of design from earlier examples of this type found in the region. The bridge truss was built by the Consolidated Western Steel Corporation of Los Angeles, California which was a division of United States Steel. Arthur L. Kiefer was the county engineer when this bridge was built. The County Executive at the time this bridge was built was Charles W. Deterding, which is noteworthy since he previously had been the county engineer, and was county engineer when earlier bascule bridges of this type were built in the county. The on-site contractor for this bridge's construction was Lord and Bishop.

Abutments and lattice railings from a previous bridge can be seen next to this bridge.
