Missouri River

The historic Lewis and Clark Bridge (Wolf Point Bridge) crosses the Missouri River six miles southeast of the city on Montana Highway 13. The adjacent 40-acre Lewis and Clark Fishing Access Site also known as Bridge Park provides access to fishing, boating, rafting, wildlife viewing, and picnicking on the Missouri River
