The Straits of Mackinac ( / ˈ m æ k ə n ɔː / MAK -ə-naw ; French : Détroit de Mackinac ) are the short waterways between the U.S. state of Michigan 's Upper and Lower Peninsulas , traversed by the Mackinac Bridge . The main strait is 3 + 1 ⁄ 2 miles (5.6 kilometers) wide with a maximum depth of 295 feet (90 meters; 49 fathoms), and connects the Great Lakes of Lake Michigan and Lake Huron . Given the large size and configuration of the straits, hydrologically, the two connected lakes are one body of water, studied as Lake Michigan–Huron . Historically, the native Odawa people called the region around the Straits Michilimackinac .
