Interstate 94 in Michigan

Interstate 94 in Michigan.
Interstate 94 (I-94) in Michigan is a part of the U.S. Interstate Highway System that runs east from the Indiana state line near Lake Michigan through the southern Lower Peninsula to Detroit, then northeast to Port Huron. I-94 extends west to Billings, Montana. In Michigan, it is a state trunkline highway serving Benton Harbor, St. Joseph, Kalamazoo, Battle Creek, Jackson, Ann Arbor, and The Thumb, terminating on the Blue Water Bridge at the Canadian border. By 1960, I-94 was completed from New Buffalo to Detroit, and most of the rest of the route was completed in the 1960s. The highway has one auxiliary route in Michigan, I-194 in Battle Creek, and eight business routes. In 1987, a plane crashed on the freeway during take-off from the airport in Detroit. The routing of I-94 contains the first full freeway-to-freeway interchange in the United States, and comprises the first complete border-to-border toll-free freeway in a U.S. state.
