While this year’s annual Labor Day walk across the Mackinac Bridge isn’t getting nearly the fanfare of last year’s 50th anniversary walk across the Mighty Mac, it’s still the one day each year that you can walk across Michigan’s engineering wonder.

The photo above is from the Opening Ceremony gallery at the Mackinac Bridge Authority web site where you can also find a Bridge Walk gallery and more information about the bridge. For a ton more photos and stories about the Mackinac Bridge, click the button below!
