The Mackinac Bridge is part of Interstate 75 (I-75) and the Lake Michigan and Huron components of the Great Lakes Circle Tour across the straits; it is also a segment of the U.S. North Country National Scenic Trail. The bridge connects the city of St. Ignace on the north end with the village of Mackinaw City on the south.Our Saint Ignace trip planner makes visiting Mackinac Bridge and other Saint Ignace attractions simple, and helps you make a travel plan personal to you.
