The Mackinac Bridge, which opened in 1957 and connects Michigan’s upper and lower peninsulas, has been named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. With a main span of 3,800 ft, it is the third longest suspension span in the U.S. and twelfth longest in the world. Its overall length between anchorages, 8,614 ft, makes it the longest suspension bridge between anchorages in the Western Hemisphere.
