Project location

US 12 (Wisconsin Dells Parkway), WIS 13 to E. Adams Street - Sauk County

Project overview

WisDOT is gathering input on a proposed highway safety project to address the high rate of crashes and pavement conditions along US 12 (Wisconsin Dells Parkway) between WIS 13 and E. Adams Street in Lake Delton and Wisconsin Dells.

The proposed improvements include a 5-lane roadway with two lanes in each direction separated by a Two-Way Left-Turn Lane (TWLTL) in the median between County A and E. Adams Street. The roadway pavement, curb and gutter would be replaced as part of the project, signals and pedestrian crossings upgraded, and a shared use path constructed on the west side of the road between County A and Olympus Road.
