Iowa 78 Bridge Replacement in Keokuk County

Posted on: August 06, 2020

AMES, Iowa – August 6, 2020 – The Iowa Department of Transportation is requesting public input for the proposed replacement of the Iowa Highway 78 bridge over the Dakota, Minnesota and Eastern Railroad, about 2.5 miles west of the city of Richland in Keokuk County, and on the proposed detour route. The project will replace the existing 292 foot x 26 foot continuous I-beam bridge with a 467 foot 2 inch x 40 foot continuous welded girder bridge.

Construction is expected to occur during the 2022 construction season.

During construction through traffic would be detoured using Keokuk/Jefferson County Road V-63, Jefferson County Road H-17, and Iowa Highway 1. It is anticipated the detour will be in place for the majority of the construction, except for the lanes crossing the bridge over the railroad (Iowa 78 mile marker 8.8). Local traffic will have access to Iowa 78 during the planned closure.
