Interstate 94

Interstate 94 (I-94) is one of Michigan's most important east-west transportation corridors. Stretching across southern Michigan from the Indiana state line to the Canadian border at Port Huron, the highway connects major population centers, industrial regions, universities, airports, and international trade crossings. As part of the national Interstate Highway System, I-94 serves as a vital route for passenger travel, commercial transportation, and economic development throughout the Great Lakes region.

Major communities along the route include:

* New Buffalo * Benton Harbor * Kalamazoo * Battle Creek * Jackson * Ann Arbor * Ypsilanti * Detroit * Port Huron
