The Mackinac Bridge Authority has announced that traffic on the Mackinac Bridge increased each month of 2015, likely due to the improving economy, lower gas prices and Michigan tourism.

It's easy to cross the bridge, just pay the toll, but what about climbing to the top?

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.

Take a look as our friends from Fox 17 went to the top of "Big Mac" in 2013.
