Iowa DOT News Release

Status of flood mitigation work on U.S. 30 west of Missouri Valley #MoRiver

Posted on: June 30, 2011

AMES, Iowa – June 30, 2011: 4 p.m. – The Iowa Department of Transportation (DOT) is reporting that work on installation of the flood barrier wall along the south side of U.S. 30 in locations west of Missouri Valley is making good progress. The present goal is to try to get the roadway reopened before the Friday morning commute.  Achievement of this goal remains contingent on steady progress throughout the rest of today. 

After the road is opened, it will remain so through the Fourth of July holiday weekend.  

The road will close again temporarily Tuesday, July 5 at 8:30 a.m. to begin work on installing a flood barrier wall on the north side of the road. That work will also be performed around-the-clock and take approximately 48 hours. Earlier it was thought that work could possibly be performed under controlled traffic conditions. However, it has been determined that the work cannot be performed safely or efficiently under those conditions.
