Interstate 75 hugs the western shore of Lake Erie upon entering Michigan -- until about Monroe, when it heads westward and prepares to enter Detroit and its surrounding suburbs. Yet another Interstate 275 is met as the freeway goes deeper into the Detroit metropolitan area, and no other major junctions are present until downtown. Once downtown, Interstate 75 meets the Ambassador Bridge to Windsor, Canada, Interstate 375 (Chrysler Freeway), Interstate 94, and M-8 (Davison Freeway). Interstate 696 also intersects I-75 in the northern metro area. When the freeway reaches Pontiac, there is a junction with M-59; and further north in Flint, the interstate meets Interstate 475 and Interstate 69. The freeway then heads north towards Saginaw, where Interstate 675 acts as a spur route into the city. Further north in Bay City, the major junction of US 10 exists, providing access to Midland as well as downtown Bay City. At Mackinaw City, I-75 crosses the Mackinac Bridge to reach the Upper Peninsula, where the road terminates at the Canadian border in Sault Ste. Marie.
