Interstate 94 (I-94) runs east–west through the western, central and southeastern portions of the U.S. state of Wisconsin. A total of 348.23 miles (560.42 km) of I-94 lie in the state.

Route description[edit]

I-894 west at the Zoo Interchange (I-94)

The route, cosigned with US 12, enters from Minnesota just east of the Twin Cities. The route passes north of Menomonie and south of Eau Claire before turning southeast and heading towards Tomah where it joins I-90. The two Interstates run concurrently for the next 91.76 miles (147.67 km) to Madison. I-94 enters the state as a six-lane facility which reduces to four-lane at exit 4 (US 12).

I-94 passes by the popular tourist destination of Wisconsin Dells.

The route converges with Interstate 39 63 miles (101 km) southeast of Tomah (near Portage). This concurrency (30 miles) is the longest three-route concurrency of the Interstate Highway system and only one of two in existence. The interchanges mark a return to a six-lane configuration.

I-94 turns eastward toward Milwaukee at what is commonly known as the "Badger Interchange" where the three interstates meet with WIS 30. The route returns to four lanes after the interchange traffic merges, then returns to six lanes just west of Waukesha. The highway remains a six-lane facility (with various auxiliary and collector–distributor lanes in Milwaukee at interchanges) east and south of this point, and through the area is officially designated the East–West Freeway, though very few organizations, including the Wisconsin Department of Transportation's traffic control center in the area actually use that name. I-94 passes through downtown Milwaukee, turning southbound and joining I-43 for six miles (9.7 km), into a road designated from Ozaukee County to the Illinois state line as the North–South Freeway.

I-94 leaves Milwaukee to the south and passes west of Racine and Kenosha on its way into Illinois toward Chicago. Traffic is heavy along this stretch.

History[edit]

I-94 was the first section of the Interstate Highway System completed within the state of Wisconsin. This seven-mile (11 km) section, between the unincorporated town of Goerkes Corners (currently at the intersection of US 18 and Barker Road) and Waukesha was built in 1956. The route was added segment-by-segment over the years and was completed to its current alignment in 1968.

From 2004 until 2008, a portion of I-94 in Milwaukee was reconstructed as a part of the Marquette Interchange project.

Current construction[edit]

Beginning in 2009 and continuing until 2021, the 35 miles (56 km) of I-94 between the Mitchell Interchange and the Illinois state line will be widened from six to eight lanes. This includes a complete rebuild of the roadway, modern frontage roads, and interchange improvements including a new design of the Mitchell Interchange in Milwaukee County.
