I have driven across the Mackinac Bridge 100’s of times and walked it once.
Once a year the Bridge is open for the Labor Day Walk.
The Mackinac Bridge is currently the third longest suspension bridge in the world. In 1998, the Akashi Kaikyo Bridge in Japan became the longest with a total suspension of 12,826 feet. The Great Belt Bridge in Halsskov-Sprogoe, Denmark, which also opened in 1998, is the second longest suspension bridge in the world with a total suspension of 8,921 feet. The Mackinac Bridge is the longest suspension bridge in the western hemisphere.
