Pure Michigan Byway) by MDOT for its "natural beauty" and access to recreational areas. History The original version of M-179 was established in 1935 as a shortcut near Le Roy between US 131 and what was M-63. That route was turned back to local control in late 1958 or 1959, and the designation disappeared from the system. (The original M-63 itself was decommissioned a few years later in 1961.) On October 1, 1998, as part of the Rationalization process, a jurisdictional transfer turned county road A-42 between US 131 and M-43 over to the state, which the state later designated as M-179 for the following year.
