U.S. Route 12 in Wisconsin

In the U.S. state of Wisconsin, U.S. Route 12 (normally called U.S. Highway 12, Highway 12 or U.S. 12) runs east–west across the western to southeast porions of the state. It enters from Minnesota (concurrently with Interstate 94) at Hudson, parallels the interstate to Wisconsin Dells, and provides local access to cities such as Menomonie, Eau Claire, Black River Falls, Tomah and Mauston. It then provides an alternative route for traffic between northwestern Wisconsin and Madison and is the anchor route for the West Beltline Highway around Madison. Finally, it serves southeastern Wisconsin, connecting Madison with Whitewater, Elkhorn and Lake Geneva. The West Beltline Highway and the segment between Elkhorn and Lake Geneva are freeways, and the segment between Sauk City and Middleton is an expressway. The remainder of the road is a two-lane surface road or an urban multi-lane arterial. Between Hudson and west of Warrens, the road closely parallels the former main line of the Omaha Road, now operated by Union Pacific Railroad.
