Replacement of two bridges and construction of two new box culverts on Highway 1, just south of Black Diamond Road south of Iowa City, will require closing the road to traffic beginning at 7 a.m. Monday, Aug. 10, until late September, weather permitting. That’s according to the Iowa Department of Transportation’s Fairfield construction office.

The 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 the Old Man’s Creek overflow.

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