Location
The Mackinac Bridge (/ˈmækənɔː/MAK-ə-naw; also referred to as the Mighty Mac or Big Mac)[4] is a suspension bridge that connects the Upper and Lower peninsulas of the U.S. state of Michigan. It spans the Straits of Mackinac, a body of water connecting Lake Michigan and Lake Huron, two of the Great Lakes. Opened in 1957, the 26,372-foot-long (4.995 mi; 8.038 km)[1] bridge is the world's 27th-longest main span and is the longest suspension bridge between anchorages in the Western Hemisphere.[5] 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 to the north with the village of Mackinaw City to the south.
Envisioned since the 1880s, the bridge was designed by the engineer David B. Steinman and completed in 1957 only after many decades of struggles to begin construction.[6] The bridge has since become an iconic symbol of the state of Michigan.[7][8][9]
