Iowa DOT News Release

U.S. 71 south of Atlantic to remain closed until mid-November for bridge replacement work

Posted on: June 07, 2018

CRESTON, Iowa – June 7, 2018 – A bridge replacement project on the U.S. 71 bridge over Lone Tree Creek, 0.1 miles south of Cass County Road G-35, and 3.1 miles south of Atlantic, may take longer to complete than planned, according to the Iowa Department of Transportation’s Creston construction office.

As crews began removing the roadway to construct the bridge extension they discovered the slide that had damaged the roadway had impacted the existing piling at the south abutment. To correct the piling, crews will need to remove the south deck of the bridge and beams to remove the bent piling before they construct the new pier. The new south abutment has been completed. The additional work will likely push the opening back to mid-November 2018. 

The Iowa DOT and our contracting partner AM Cohron are committed to making the necessary repairs and getting the roadway opened as quickly as possible.

During this closure, traffic will be detoured around the work zone using Iowa 83, Iowa 92, and Iowa 148.

The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
