The Chief Standing Bear Memorial Bridge is a bridge across the Missouri River at the Nebraska-South Dakota border. Located near Niobrara, Nebraska, not far downstream from the confluence of the Niobrara River with the Missouri, it joins Nebraska Highway 14 to South Dakota Highway 37. The bridge is named for Standing Bear, a Ponca chief born and buried nearby, who was the plaintiff in Standing Bear v. Crook, a landmark 1879 U.S. District Court case that established the legal rights of Native Americans to move about freely.
