The Wisconsin Department of Transportation is rehabilitating the bridge over the Wisconsin River on Highway 23 from County Highway C in Iowa County to approximately 1,000 feet north of the bridge in Sauk County.
Kraemer, the contractor rehabilitating the bridge, closed the bridge Oct. 26 and expects it to remain closed through the winter and spring 2021. The bridge is to be open to traffic (likely one lane that will utilize traffic signals to alternate traffic between northbound to southbound vehicles) in June 2021. The entire project is to be completed and the bridge fully open to traffic in September 2021.
While the bridge is closed, traffic will be detoured using state routes through Lone Rock, U.S. Hwy 14 and County Highway C.
This bridge rehabilitation project includes the removal and replacement of the concrete bridge deck, repainting of the steel girders, minor earthwork for the upgrading of beam guard and minor roadway work near the bridge. The project cost is estimated at approximately $3 million.
The river under the bridge will be a work zone during construction. The river will remain open to boaters, but some portions will be restricted for boater’s protection. Be alert for crews working and use caution when navigating this area. Buoys will be placed for your safety to guide your navigation through the work zone.
