The Lost Bridge was a bridge that was built over the Little Missouri River in 1930, north of Killdeer, North Dakota, on North Dakota Highway 22. A road to the bridge was finally built 20 years later, hence the name. The Lost Bridge was dismantled in 1994. A plaque and a piece of the old bridge have been installed on Route 22 near the new bridge as a memorial.
