Prior to 1962, M-30's southern terminus was at the junction with M-46 in Merrill. Since then, the segment south of US Highway 10 (US 10) was returned to local control and decommissioned as a state highway. In May 2009, M-30 was extended southerly from US 10 to M-20, restoring some of the highway decommissioned in the 1960s to M-30. It was then extended back to M-46 in 2022.
