The Interstate Highways in Michigan are the segments of the national Dwight D. Eisenhower System of Interstate and Defense Highways that are owned and maintained by the U.S. state of Michigan, totaling about 1,239 miles (1,994 km). The longest of these, Interstate 75 (marker pictured), is also the longest highway of any kind in the state. The Interstates in Michigan have their origins in World War II-era expressways built in the Detroit area. After the system was created in 1956, the state highway department completed its first border-to-border Interstate in 1960. The last highway was completed in 1992, giving Michigan a total of 13 Interstate freeways. There are also 26 current business routes that connect cities bypassed by the Interstates; 23 are business loops that connect on both ends to their parent highway, and three are business spurs that connect on only one end.
