Update: Milltown has a new pedestrian bridge!

November 2008 Exciting news in Milltown, with the dedication of a new pedestrian bridge across the Blackfoot River as it runs into the Clark Fork River. The span – known as the “Black Bridge” was originally built in 1921 and has been in the process of refurbishment since last December as part of the ongoing EPA Superfund cleanup project, which included removal of the Milltown Dam in March 2008. Go out to Milltown and enjoy the Missoula-area’s latest facility for people-powered transportation!

Previously written

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.
