Assembly Bill 155 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 in Sauk County as the Tom Diehl Memorial Highway. This designation serves to honor Tom Diehl and is part of a broader initiative to recognize significant individuals through highway naming.

The bill was introduced by a group of representatives and is co-sponsored by several senators, reflecting bipartisan support. It has been referred to the Committee on Transportation for further consideration. The bill includes a fiscal estimate that will be provided as an appendix, indicating potential costs associated with the designation and marking of the highway.
