M-95 was rerouted in 1942 from Republic north to Humboldt Township. This new section replaced the last section of gravel roadway that was transferred to Marquette County as County Road 601. Another rerouting in the Republic area moved the trunkline in 1957 to bypass South Republic. The former roadway was partially closed to become part of the Republic Mine. M-69 was shortened, eliminating the concurrency with M-95 in 1960 or 1961. M-69 was re-extended back to its pre-1960 routing in 1991, restoring the concurrency in the process.
