Bridge Documentation

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

This bridge was completed in 1932 and is an increasingly rare example of a riveted cantilever truss bridge. In 1965, a second cantilever truss bridge was built to form a one-way couplet of bridges. Today the bridges are commonly called the Twin Bridges, although when looking at the bridges it is obvious they are anything but twins, since the two bridges both have the design details of the period in which they were built, such as more v-lacing and lattice on the built-up beams of the 1932 span.

The bridge was designed by noted firm Modjeski and Masters, a company with extensive experience designing cantilever truss bridges.

The bridge's approach system consists of Warren deck truss spans and deck plate girder spans.
