Mackinac Bridge History – World’s Super Structures Documentary Film
Mackinac Bridge, is a suspension bridge extending the Straits of Mackinac to link the Upper as well as Lower peninsula of Michigan. Opened up in 1957, the 8,614-foot (2,626 m) bridge is the world’s 16th-longest in total suspension and also the lengthiest suspension bridge in between anchorages in the Western hemisphere. The Mackinac Bridge brings Interstate 75 as well as the Lakes Michigan and Huron elements of the Great Lakes Circle Tours across the straits and links the city of St. Ignace on the north end with the town of Mackinaw City on the south.
