a longer route that also connected the modern-day Saginaw with Mackinaw City and the Straits of Mackinac. Until 1933, no roadway was built along the path of the Indian trail. After that year, US 2 was rerouted between St. Ignace and Sault Ste. Marie using the modern routing of H-63. This placed the Mackinac Trail on the state trunkline highway system for the first time. In 1962 and 1963, the state transferred the highway to county control when US 2 was rerouted to follow the completed I-75 freeway. With the transfer to local control, Mackinac Trail became a county road. Later, it was given the H-63 designation after October 5, 1970, as part of the County-Designated Highway System. The designation on the 1971 state map follows the routing used today.
