Photographer's Note

This was taken at a scenic overlook. In the background you see the Mackinac bridge, a golf course, and a bright blue sky.

The Mackinac bridge is currently the 5th longest suspension bridge. The bridge was open to vehicles on November 1, 1957.

The width of the roadway is 54 feet. The outside lanes are 12 feet wide (2), the inside lanes are 11 feet wide (2), the center mall is 2 feet wide, and the catwalk, curb and rail width is 3 feet on each side - totaling 54 feet. The stiffening truss width in the suspended span is 68 feet wide making it wider than the roadway it supports.

The height of the roadway at mid-span is approximately 200 feet above water level. The vertical clearance at normal temperature is 155 feet at the center of the main suspension span and 135 feet at the boundaries of the 3,000 ft. navigation channel.
