[edit] History

Before any segment of freeway in Michigan received a designation of Interstate 75, there were already segments of freeway built which are now part of I-75. These freeway segments were built from the mid to late 1950s; they include:

U.S. Route 2 between what is now known as BL I-75 in St. Ignace and M-123. The upper peninsula's first segment of freeway.
Alt U.S. Route 24 between Ohio border and U.S. Route 25 (now M-125) - Michigan's first segment of freeway to connect the state border; and the only freeway to cross the border until the late 1960s.
Mackinac Bridge (then U.S. Route 27)
M-20 (now part of U.S. Route 10) - when this segment of freeway became U.S. Route 10; it carried the temproary Interstate 75 designation.
