History

The first section of I-94 completed with Interstate funds (under the Federal-Aid Highway Act of 1956) was a section between Jamestown and Valley City, North Dakota, in 1958. North of

, I-94 has been widened from six to eight lanes from Illinois Route 22 (IL 22, Half Day Road) to just south of the Wisconsin state line at IL 173 and 95th Street to 159th Street. Construction began in 2009 to completely rebuild I-94, including expansion to eight lanes, from the Wisconsin–Illinois border through the Mitchell Interchange in Milwaukee. This construction is expected to be completed in 2021. In 2005, the I-94 bridge over the Crow River near St. Michael, Minnesota, about northwest of

, was rebuilt. In 2006, a project to widen I-94 east of Downtown Saint Paul between MN 120 and McKnight Road from four to six lanes was completed. The interchange at 95th Avenue North in Maple Grove, Minnesota, was rebuilt with a new, wider bridge that replaced the two-lane bridge there, which was demolished in July 2006. The expanded Marquette Interchange in Downtown Milwaukee was completed in August 2008 at a cost of $810 million (equivalent to $ in ). In Detroit, I-94 was routed over the existing Edsel Ford Freeway and remained signed as such until the late 1980s when Michigan deemphasized proper names on Interstate guide signs. Its interchange with the Lodge Freeway, built in 1953, is significant as the first full-speed freeway-to-freeway interchange built in the US. From September 2007 to October 2008, the
