Iowa DOT provides update on status of Iowa 175/Decatur bridge site #MoRiver

Posted on: September 23, 2011

AMES, Iowa – Sept. 23, 2011 – The Iowa Department of Transportation (DOT) is providing an update on the status of the Iowa 175/Decatur bridge site, which has been impacted by the Missouri River flooding since early June.

A reduction in the water discharge of the Missouri River at Decatur, Neb. from its peak of 160,000 cubic feet per second (cfs) to 86,200 cfs (Sept. 23, 2011; 9 a.m.), has allowed the Iowa DOT to perform additional tests and field examinations at the site.

A new test was performed this week that confirmed a scour hole is still present around the bridge piers, abutment and embankment on the east side of the Missouri River. The scour hole must be corrected prior to opening the road and bridge.

The Iowa DOT is attempting to let an emergency contract to protect the bridge and approach embankment.  Work on the project will be performed when conditions at the site permit. Every effort is being made to restore traffic on the bridge/road yet this year.

Additional details about the Iowa DOT’s flood recovery efforts are available at:  Periodic updates on recovery activities are posted on this site, as well as photos of flood damage and rebuilding.
