Release date: February 24, 2026

The Wisconsin Department of Transportation (WisDOT) is holding a public involvement meeting to share details about a bridge rehabilitation project on WIS 79 in Dunn County and obtain public input.

Built in 1945 and 1955 respectively, the bridges over the south fork of Hay River in the town of Tiffany and Tiffany Creek in Boyceville are showing signs of deterioration. To address this, the Wisconsin Department of Transportation is proposing the following at:

Crews also will be removing brush and trimming trees at rail crossings on WIS 79, Center Street and 130th Street. Roadway widening is planned at the latter as well.

During construction, WIS 79 will be closed at the South Fork Hay River Bridge. The proposed detour route uses WIS 170, WIS 128 and WIS 64. At the Tiffany Creek Bridge, work will be completed using single-lane closures controlled by temporary traffic signals. In addition, traffic on 130th Street will be detoured during road widening via WIS 170 and 1010th Avenue.

Construction currently is scheduled for 2029.

More information about the project can be found on the project’s website, including a comment form. Comments on the project are being accepted through March 20.
