Scenic Bridge, Deck truss road bridge in Mineral County, Montana, US

Scenic Bridge is a riveted Pratt deck truss bridge carrying Old U.S. Route 10 West over the Clark Fork River about 4 miles east of Tarkio. Its three main spans rest on reinforced concrete abutments and piers, and the structure measures 421 feet long and 25 feet wide, with a 24-foot roadway.

The bridge was built during a period when new transportation routes advanced settlement in Montana. Its listing on the National Register of Historic Places honors its contribution to the region's infrastructure history.

The bridge connects local communities and shows how the region developed through transportation networks. It shapes the landscape today and is used daily by those who live nearby.

The bridge carries Old U.S. Route 10 West at Milepost 0, about 4 miles (6.4 km) east of Tarkio, so it is reached by road from that direction. Its deck is 25 feet (7.6 m) wide with a 24-foot (7.3 m) roadway, and the structure rests on reinforced concrete abutments and piers.

The Pratt deck truss was chosen by state staff only for relatively rare circumstances between 1928 and 1932; after that, a version of the Warren truss design was used. The Scenic Bridge, completed in 1928, is one of the structures from that short window. Its main span measures 191 feet (58 m).
