The annual Mackinac Bridge walk will continue and be held on Labor Day Monday, but with a revised format to address security concerns, the Mackinac Bridge Authority decided Friday.

According to the Lansing State Journal, the board voted to revise the format to allow walkers to start from either direction and either turn around at the midway point of the bridge or arrange for transportation back to their starting point.

The revised plan eliminates the need for busing, which can be costly and logistically challenging.

The format had to change to comply with recommendations from the Michigan State police and the U.S. Department of Homeland Security that the bridge be closed to vehicular traffic during the annual walk.
