The Wisconsin Department of Transportation (WisDOT) is rehabilitating the bridge over the Wisconsin River on Highway 23 from County Highway C in Iowa County to approximately 1000 feet north of the bridge in Sauk County.


A public meeting is scheduled for WEDNESDAY, OCTOBER 7TH, 2020 at 5:30 PM on a teleconference line.  To access the teleconference, call the following the phone number, 1-608-581-9341, and enter the Conference ID of 879 080 431#.  The objective of this meeting is to share project information and the construction schedule as well as answer project specific questions.


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 $3,039,000.

Kraemer is the contractor that will be rehabilitating the bridge.  Kraemer plans to close the bridge on Monday, October 19, 2020.  The bridge will remain closed through the winter and spring of 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 of 2021.  They entire project is to be completed and the bridge fully open to traffic in September of 2021.

When the bridge is closed traffic will be detoured using nearby state routes.  The signed detour route utilizes STH 130, STH 133 through Lone Rock and USH 14. 

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.  See the attached “Boater Information” flyer that is also available on the project’s website.
