Orange Street Bridge, Spanning Clark Fork River at Orange Street, Missoula, Missoula County, MT

Significance: The bridge is one of only 14 steel deck truss bridges designed and constructed by the Montana Department of Transportation between 1920-1952. It comprised a standard design developed by the department after 1932. There were only 15 bridges displaying this aesthetically distinctive design in Montana. The bridge history as a 1930s New Deal "make work" project is also well documented and included a labor strike by the local unions to protest the low wages stipulated by the Federal government's Emergency Relief Act of 1935. The bridge is also the only remaining structure in Montana constructed by the Portland Bridge Company of Portland, Oregon.
