U.S. 30 in Harrison County to close temporarily to install flood barrier wal


June 28th, 2011 by Ric Hanson

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.
