M-21 was designated by July 1, 1919 on a routing from Ionia to Goodells. Along the way, it ran through Lyons and Pewamo, joining its current routing to Ovid. M-21 continued through Corunna to Lennon and Flint. There it joined its last routing between Flint and the Port Huron area. The highway was extended to Port Huron by 1924, and the west end was extended to Grand Rapids in 1925 along M-16

A Bypass M-21 (Byp. M-21) designation was created in the Grand Rapids area in 1945. This designation ran from the corner of 28th Street and Chicago Drive along Byp. US 16 and Byp. US 131 on 28th Street. At East Beltline Avenue, Byp. US 131/Byp. M-21 turned north back to M-21. M-21A in Flint was turned over to local control in 1948, decommissioning the number. The Byp. M-21 routing was replaced by M-21 in 1953. The former routing in Grand Rapids became Bus. M-21 instead.

. The 1974 completion of I-196 meant the truncation of M-21 to end in Grand Rapids. At the time, M-21 was extended along Fulton Street to the East Beltline, and the business loop was truncated into a spur route redesignated BS I-196. The remaining segment of freeway connecting Flint with Port Huron opened in 1984 as I-69, and M-21 was shortened to Flint. M-56 was replaced by M-21 at this time as well. The former M-21 in Port Huron became BL I-69, and the remainder was turned back to local control.
