Iowa DOT News Release

U.S. 30 in Harrison County to close temporarily to install flood barrier wall #MoRiver

Posted on: June 27, 2011

AMES, Iowa – June 27, 2011- The Iowa Department of Transportation (DOT) is announcing plans to temporarily close U.S. 30 between Missouri Valley, Iowa, and Blair, Neb., beginning Wednesday, June 29, at 8:30 a.m.  

The purpose of the closure is to install a Trapbag® flood-control barrier along the south side of the roadway. The urgency of getting the barrier wall installed will require a number of workers, many trucks and heavy equipment, and will take the entire roadway area to perform the work.

The Iowa DOT’s plan is to run an around-the-clock operation to expedite reopening of the road.  The road could possibly be reopened as soon as 48 hours after the start of the project. Timing of completion of the work is dependent on a number of factors, including equipment reliability, rising flood water levels, weather conditions, and other issues.

The Iowa portion of the detour, established for persons traveling from Missouri Valley, Iowa, to Blair, Nebr., is: I-29 south to I-680E, take I-680E to I-80W, and then take I-80W to the Iowa/Nebraska state line at Council Bluffs/Omaha.

The public will be notified when the roadway is reopened to travel.

When the roadway is reopened, work on a barrier wall on the north side of the roadway will begin. This work may result in brief temporary closures, a lane closure and use of pilot vehicles or flagging operations. 

Drivers must exercise additional caution while traveling on the roadway during installation of the barrier wall.  Workers and equipment will be in close proximity to the travel lane.  Slow down for conditions and obey all signs and instructions.
