Interstate 394 (I-394) is a short east–west auxiliary Interstate Highway in Hennepin County in the US state of Minnesota. It is also commonly referred to by its pre-1991 name, Wayzata Boulevard, and by its other designation for most of its route, US Highway 12 (US 12). It runs for 9.8 miles (15.8 km) from downtown Minneapolis to I-494 in the Minneapolis suburb of Minnetonka. At its western terminus, the roadway loses its Interstate designation but continues as US 12. I-394 serves as the most direct link for commuters and other drivers who are traveling between downtown Minneapolis and parts of the western Minneapolis–Saint Paul metropolitan area.
I-394 maintains at least three lanes in each direction except under the Minnesota State Highway 100 (MN 100) interchange and also between I-94/US 52 and its eastern terminus downtown.
