Assembly Bill 155 proposes the designation of a section of USH 12 in the village of Lake Delton, Sauk County, as the Tom Diehl Memorial Highway. The bill mandates that the Department of Transportation is responsible for the designation and marking of this highway segment to honor Tom Diehl.

To implement this designation, the bill creates a new statute, 84.1054, which specifically outlines the requirement for the Department of Transportation to mark the entire portion of USH 12 within the specified area as the Tom Diehl Memorial Highway. This initiative aims to recognize and commemorate the contributions of Tom Diehl to the community.
