Officially, the entire length of I-75 in Michigan is the American Legion Memorial Highway. As a practical matter, this name is not used on the southernmost segments of the Interstate. The American Legion was honored with the designation in 1969 in a state law that required private interests to finance the signage. Public Act 174 of 1984 redesignated I-75 in honor of the group and placed responsibility for signage in MDOT's hands. Another name that was applied to all of I-75 was the Michigan Bicentennial Freedom Way. Designated by Senate Concurrent Resolution 216 of 1975, the name only applied to the freeway in 1976. The designation was formally repealed in 2001.
