The Iowa Department of Transportation’s Council Bluffs Construction Office says the DOT is replacing the Iowa 92 bridge over Little Silver Creek one mile west of Treynor using  accelerated bridge construction (ABC) techniques. The project requires closing the roadway to traffic beginning Thursday, Oct. 22nd, until Wednesday, Nov. 11th, weather permitting.
During the three-week construction closure,  motorists will be detoured around the construction zone using Pottawattamie County Road L-55 north for four miles to U.S. 6, then U.S. 6 west for nine miles to the I-80 interchange, and then traveling southwest on Interstate 80 to Interstate 29 and south to the Iowa 92 interchange.
Eastbound Iowa 92 and northbound I-29 traffic will also be impacted by the northbound ramp closures at the I-29/Iowa 92 interchange. These motorists are required to use the existing detour on Iowa 192/South Expressway in Council Bluffs.

The ABC process uses numerous innovative technologies that makes the project safer and significantly shortens the construction schedule so the road is closed for fewer days, saving travelers time and money by not having to use a detour around the site for an extended period.  Using traditional techniques, this bridge replacement could have resulted in a closure of six months or more.
