Lewis and Clark Bridge, Historic steel bridge in Wolf Point, Montana, US

The Lewis and Clark Bridge is a five-span Pennsylvania through truss crossing the Missouri River between McCone and Roosevelt counties at Wolf Point. Its 400-foot main span is the longest through truss span in Montana. The Missouri Valley Bridge and Iron Company completed the steel structure in 1930.

Completed in 1930 by the Missouri Valley Bridge and Iron Company, the bridge was the first crossing of the Missouri River at Wolf Point and the only one along a 350-mile stretch of the river. Its opening on July 9 drew more than 10,000 visitors, with five bands and a fireworks display. It was listed on the National Register of Historic Places on November 24, 1997.

The bridge bears the names of the Lewis and Clark expedition and connects communities in territory traditionally home to the Assiniboine and Gros Ventre peoples. Visitors crossing it today experience a physical link to the region's exploration history.

The bridge is open to both vehicles and pedestrians and connects McCone and Roosevelt counties across the river. Visitors can access the structure from either riverbank and enjoy views of the Missouri River while crossing.

The opening celebration in 1930 was a major regional event featuring multiple bands and fireworks that drew thousands of people. This grand ceremony reflected how important communities considered the new link across the river.
