US 12 Corridor, aka Baraboo Bypass - South section - Need/purpose

Why is this project needed?

This section of US 12 serves as a prime tourism center with the various natural areas – Devil’s Lake and Mirror Lake State Parks, the many attractions in Lake Delton, Baraboo and Wisconsin Dells area.

Project benefits/anticipated outcomes

Safer and more efficient roadway on US 12 around Baraboo south to the existing four-lane roadway.

Majority of US 12 will be reconstructed from two lanes to four lanes to move traffic more efficiently, especially during the summer months when traffic volumes increase threefold.

Safety will be improved by:

  • Removing direct access to businesses/homes along the freeway portion around Baraboo.
  • Allowing access only at the following two interchanges:
    • WIS 136
    • County W
  • South of Baraboo, the freeway will change to an expressway with limited access to some businesses/homes and full access to the Lehman Rd. and Ski Hi Rd. intersections.
