Interstate 94 (I-94) is an east–west Interstate Highway connecting the Great Lakes and northern Great Plains regions of the United States. Its western terminus is just east of Billings, Montana, at a junction with I-90; its eastern terminus is in Port Huron, Michigan, where it meets with I-69 and crosses the Blue Water Bridge into Sarnia, Ontario, Canada, where the route becomes Ontario Highway 402. It thus lies along the primary overland route from Seattle (via I-90) to Toronto (via Ontario Highway 401) and is the only east–west Interstate Highway to have a direct connection to Canada. It is the longest Interstate whose route number is not divisible by 5.

I-94 intersects with I-90 several times: at its western terminus; Tomah to Madison in Wisconsin; in Chicago, Illinois; and in Lake Station, Indiana. Major cities that I-94 connects to are Billings, Bismarck, Fargo, Minneapolis–Saint Paul, Madison, Milwaukee, Chicago, and Detroit.
