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 will involve appropriate signage to reflect the memorial status of the highway.

The bill was introduced by a group of representatives and is co-sponsored by several senators, indicating a collaborative effort to recognize Tom Diehl's contributions. The bill has been referred to the Committee on Transportation for further consideration.
