H-63 (Michigan County Highway)

H-63 (Michigan County Highway)

H-63 is a county-designated highway (CDH) in the Upper Peninsula of the US state of Michigan. The highway parallels the Interstate 75 (I-75) corridor between St. Ignace and Sault Ste. Marie. The road is called Mackinac Trail after the Upper Peninsula branch of an Indian trail used before European settlers reached the area. Originally, the roadway was built as a section of US Highway 2 (US 2) before being added to the CDH system in the 1970s.

H-63 serves as a two-lane alternative to the I-75 freeway across the eastern end of the Upper Peninsula. Between the northern side of St. Ignace, the roadway has connections to two state highways before running concurrently with M-48 near Rudyard. H-63 ends on the south side of Sault Ste. Marie.
