Tower Tour Certificates

The Mackinac Bridge Authority holds a drawing once per year each August, and randomly chooses 25 non-profit organizations to receive a tower tour certificate to be raffled or auctioned for charitable purposes.   The certificates can be used May 1st through October 15th of the following year, and are good for two people.  Organizations can download the form below and mail it back to be entered into the drawing.
