Unprocessed field note material exists for this structure (N398).
Significance: The Red Bank Creek Bridge on Rawson Road is one of the few remaining bridges erected by the Pacific Bridge Company of San Francisco. In addition, it is also a rare California example of a truss bridge with non-structural, architectonic decoration, here in the form of Classical urns atop the end posts. This bridge, with its Pratt truss main span, was determined eligible for inclusion on the National Register of Historic Places under Criterion C at the local level of significance.
