Accelerated Bridge Construction Demonstrated in Pottawattamie County
What happened
The replacement of the U.S. 6 bridge over Keg Creek in Pottawattamie County utilized accelerated construction techniques. The bridge was completely prefabricated off-site, allowing the road to close for 16 days instead of the estimated six months required by conventional methods. The Federal Highway Administration described this project as a first in the United States for completely prefabricating and installing the new bridge system off-site.
