SIDNEY, Iowa (AP) — Officials say some overpasses and ramps along Interstate 29 in western Iowa need to be inspected for flood damage before they’re judged safe.

Iowa Transportation Department officials say that damage could take months to repair and hamper travel along the interstate and on the approaches to bridges across the Missouri River to Nebraska.

Near Sidney, river floodwater has washed away some of the dirt on the overpass where Iowa Highway 2 and Interstate 29 meet.

Department spokesman Jeff McQueen says the overpass and ramps will have to be inspected and repairs made before motorists can use them for travel north or south along I-29 or to exit for driving northeast into Sidney or west to Nebraska City, across the Missouri River.
