Originally determined Category 4 (not evaluated) in the Caltrans 1985 Historic Metal Truss Bridges in California Thematic Resources study; it was evaluated and determined eligible in the 2004 Caltrans Historic Bridge Inventory update: Metal Truss Bridges.
Albion River Bridge (10 0136), built in 1944 during World War II, is composed of a steel, rigid-connected Baltimore petit deck truss span, and a timber stringer and timber truss span with reinforced-concrete tower bents. The design and method of construction of the combination steel and timber structure is important because it physically manifests this historic context significant to California's war-time history. With wartime restrictions on critical building materials, the Division of Highways designed the bridge with less steel, concrete, and redwood than normally used. Overcoming the rationing of building materials was essential to California's contributions to the war effort. Furthermore, the bridge is a relatively rare type because during World War II the Division of Highways built few large bridges on non-essential military routes. Albion River Bridge appears to be the only remaining example of a bridge designed and constructed during the war on a secondary roadway.
