Two other segments near the Straits of Mackinac were named in 1976 for figures instrumental in the construction of the Mackinac Bridge. From the Cheboygan–Otsego county line north to the bridge, I-75 was named for G. Mennen Williams, the former governor once called "Michigan's Politician of the Century" in the press. The section in Mackinac County from the northern end of the Mackinac Bridge was named for Prentiss M. Brown, the former Congressman and Senator who served on the MBA board until his death in 1971.
