Bridge closures on Iowa 1 south of Iowa City begin Monday, Aug. 10

Posted on: July 28, 2020

FAIRFIELD, Iowa – July 28, 2020 – Replacement of two bridges and construction of two new box culverts on Iowa 1, just south of Johnson County Road F-52, south of Iowa City, will require closing the road to traffic beginning at 7 a.m. Monday, Aug. 10, until  late September, weather permitting, according to the Iowa Department of Transportation’s Fairfield construction office.

This project involves the replacement of the existing steel girder bridge over Old Woman’s Creek with a concrete beam bridge, and replacement of the existing steel bridge over Old Man’s Creek with a rolled-steel bridge. In addition, two new reinforced concrete box culverts will be constructed at Old Man's Creek overflow.

The prime contractor on this project is Kraemer North America, LLC. To allow for quicker bridge construction, the contactor is using accelerated bridge construction methods and are working under an aggressive schedule to complete their work. 

Through traffic will be directed to use an official off-site detour (see map). The 19.3-mile marked detour will follow Iowa 22 and U.S. 218/Iowa 27. It is anticipated the detour will be in place until late September, weather permitting. Local traffic will have access to Iowa 1 except for the bridges crossing over Old Man’s Creek (Iowa 1 near mile marker 78) and over Old Woman’s Creek (Iowa 1 near mile marker 79).  

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.
