US 12/Baraboo Bypass

US 12, I-90/94 (Lake Delton) to Ski Hi Rd. (south of Baraboo), in Sauk County.

North section – Need/purpose

Note – Construction completed 2011 and roadway open to traffic.

West Fern Dell roundabout.

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

Safer and more efficient roadway between Lake Delton and the existing four lane roadway north of Baraboo.

The 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 freeway portion (I-90/94 south to Baraboo).
  • Allowing access only at three interchanges:
    • Fern Dell Rd.
    • North Reedsburg Rd.
    • WIS 33
