The Burt County Missouri River Bridge is a truss bridge over the Missouri River connecting Burt County, Nebraska and Monona County, Iowa at Decatur, Nebraska. It is one of three toll bridges in Nebraska.
The bridge connects Nebraska Highway 51 and Iowa Highway 175. Interstate 29 is 7 miles east and Onawa, Iowa 8 miles east of the Missouri River.
The bridge was finished in 1951 and carried the first traffic in 1955 after the US Army Corps of Engineers diverted the river to flow under the bridge.
