Bridge Documentation

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

This bridge is one of two exceedingly rare and highly significant examples  in Sonoma County of truss bridges with Phoenix columns, a unique type of built-up beam invented, patented, and produced by the Phoenix Iron Company. Bridges containing them were usually built by the Phoenix Bridge Company of Phoenixville, Pennsylvania or Dean and Westbrook of New York, New York. Also, most of the small number of surviving Phoenix column bridges are in the northeastern United States. Surviving examples in the western United States are exceptionally rare.
The sign at the bridge states that the bridge was built in 1909 and relocated to this site in 1937. However, 1909 would be exceedingly late for an initial construction of a Phoenix column bridge. It is likely that the initial construction is even earlier. Perhaps the 1909 date also refers to a relocation which would suggest the bridge has been moved twice over its life.
Overall the bridge has excellent historic integrity. A turnbuckle on one of the diagonal members is spliced in.
