Milltown Bridge, Spanning the Blackfoot River on Anaconda Street, Milltown, Missoula County, MT

Significance: The bridge is associated with the early 20th century development of Montana's highway system. The bridge provided an important vehicular connection across the Blackfoot River on a state highway in western Montana. The bridge was a component of the Yellowstone Trail, an early interstate highway that later became known as US Highway 10. The bridge is an excellent example of riveted Parker through truss, the first built under a standardized design developed by the Montana Highway Department in 1915. Bypassed by the Montana Department of Transportation in 1950, the bridge has not been modified or altered in any way and is a good representative example of a riveted Parker through truss.
