For the third year in a row, the Michigan Department of Transportation is giving someone a once-in-a-lifetime tour to the top of the Mackinac Bridge. Along with the Mackinac Bridge Authority, MDOT is asking the public to share their Labor day experiences on social media with photos and videos. One person sharing their memories will be chosen at random to win a tour of the Mighty Mac.

Through Monday, September 8th, people can post their memories of walking the bridge - either this year or previous years - on Instagram or Twitter using the hashtag #MightyMacWalk14. They can also be posted to MDOT's Facebook page here to be entered into the contest.

The winner will receive a tour for two to the top of the bridge courtesy of the MBA. A gift pack of Pure Michigan merchandise that includes hats and t-shirts will also be awarded to the person who travels the furthest this year to walk the bridge and then share their memories with MDOT.
