Iowa 92 Bridge Replacement, Mahaska County

About the Project

Project description

The Iowa Department of Transportation is requesting public input for the proposed replacement of the existing Iowa 92 bridge over the North Skunk River, about 2.6 miles east of the city of Rose Hill in Mahaska County, and proposed detour route. The project includes replacing the existing 3 span, 385 ft. x 30 ft., continuous I-beam bridge with a 3 span, 469 ft. x 44 ft. pre-tensioned prestressed concrete beam bridge.

Construction is expected to occur during the 2022 construction season. During construction through traffic would be detoured using Iowa 23, Iowa 149, and Iowa 21. It is anticipated the detour will be in place for the majority of the construction. Except for the lanes crossing the bridge over North Skunk River (IA 92 mile marker 193.3) local traffic will have access to Iowa 92 during the planned closure.

The North Skunk River is a known paddling route that will be temporarily closed during construction. This measure is being taken to ensure user safety. The Iowa DNR’s Interactive Paddling Map found at will provide hazard status information so users may plan accordingly.
