Wisconsin Highway 312

Wisconsin Highway 312

State Trunk Highway 312 (often called Highway 312, STH 312 or WIS 312) is a 7.9-mile (12.7 km) long Wisconsin state highway running along the north side of Eau Claire, from the Town of Union in the west to the Town of Seymour in the east. The entire length of Highway 312 is an expressway with a few grade crossings.

The highway is a major transit route, bypassing the north side of Eau Claire by connecting I-94 with U.S. 53. The route number is derived as a "spur route" of U.S. 12. Wisconsin Highway 312 is called the North Crossing in the Chippewa Valley, and as of July 2008, remains signed as "Formerly STH 124", for its former designation.
