ABOUT THE PROJECT
The Iowa DOT, a national leader in accelerated bridge construction (ABC), accomplished another “first.” The U.S. 6 bridge over Keg Creek in Pottawattamie County was completely prefabricated off-site. The roadway was closed for two weeks for the bridge replacement. Traditional construction methods would have required the partial or complete closure of the road for several months, resulting in substantial traffic disruption.
