 M-36 supplanted the former M-49 designation between Mason and Whitmore Lake in late 1930; segments of M-49 through Stockbridge not used in the new M-36 were given to M-92 or M-106.The last segments were paved in late 1940 between Plainfield and the eastern terminus.When the Michigan State Highway Department completed a US 127 bypass around Mason in late 1946 or early 1947, M-36 was extended westward over a section of highway previously used by US 127 to connect to the bypass; that segment was designated Bus.
