The Mackinac Bridge is a suspension bridge spanning the Straits of Mackinac connecting the city of St. Ignace with the village of Mackinaw City, Michigan. Opened in 1957, the bridge (familiarly known as "Big Mac" and "Mighty Mac") is the third longest in total suspension in the world and the longest suspension bridge between anchorages in the Western hemisphere.
Mackinac Bridge connecting upper and lower Michigan. It is approximately 5 miles long from shore to shore. We traveled over the bridge last summer. It crosses the straits between Lake Michigan and Lake Huron.
