STS068-230-085 Straits of Mackinac, Michigan, U.S.A. October 1994
An important link in the Saint Lawrence Seaway, the Straits of Mackinac, 4 miles (6 kilometers) wide at their narrowest point, are apparent in this south-looking, low-oblique, sunglint-reflected photograph. The Mackinac Straits Bridge (barely discernible), third longest suspension bridge [3800 feet (1159 meters) long] in the world, opened in 1957. Three islands are readily visible--Round Island, the smallest; Mackinac; and Boise Blanc, the largest of the three, south of which lies the city of Cheboygan. Interstate Highway 75 traverses north-south.
