Iowa DOT News Release

Posted on: June 27, 2011

AMES, Iowa – June 27, 2011 – The Iowa Department of Transportation (DOT) is reporting that Iowa 175 is closed from Interstate 29 west across the Missouri River into Nebraska due to flooding. This is the river crossing between Onawa, Iowa, and Decatur, Neb.

Severe river bank erosion caused by flooding along the east abutment of the Decatur bridge has prompted the closure. 

The Iowa DOT, Burt County [Nebraska] Bridge Commission (operator of the toll bridge) and Nebraska Department of Roads will be conducting an assessment of the situation to determine what, if any, measures can be taken to prevent further erosion and make the bridge safe for travel.  

The public will be informed as additional information becomes available. The duration of the closure is unknown at this time.

The Iowa portion of the detour for this closure, for persons traveling from Onawa, Iowa, to Decatur, Neb., is: I-29 north to Sioux City, I-29 west to the U.S. 77 exit, then south on U.S. 77 into Nebraska.
