(WXYZ) - The Michigan Department of Transportation and the Mackinac Bridge Authority are taking to social media to have people share their memories of the Mackinac Bridge Walk.
It's all part of MDOT's third annual "Tell Us Your Story" promotion.
Through Monday, September 8 you can post memories of walking the bridge either this year or in a previous year.
They're asking the public to share their memories on Instagram, Twitter and Facebook. On Instagram and Twitter you can share by using the hashtag #MightyMacWalk14. You can also post your memory on their Facebook page: www.facebook.com/MichiganDOT.
One person's memories will be chosen by computer to win a tour for two of the top of the Mackinac Bridge.
The person who travels the furthest to walk the bridge this year and shares their memory with MDOT will also win a Pure Michigan Prize Pack.
MDOT employees and their families are not eligible for either prize.
