Senate Bill 160 proposes the creation of a new statute, 84.1054, which mandates the Wisconsin Department of Transportation to designate and mark the entirety of USH 12 within the village of Lake Delton, Sauk County, as the Tom Diehl Memorial Highway. This designation serves to honor Tom Diehl and is part of a broader effort to recognize significant individuals through highway naming.

The bill was introduced on March 27, 2025, by a group of senators and representatives and has been referred to the Committee on Transportation and Local Government for further consideration. The legislative analysis indicates that a state fiscal estimate will be provided as an appendix to the bill, although specific financial implications are not detailed in the summary.
