High Wind Alert at Mackinac Bridge


Currently  the Mackinac bridge is experiencing winds of sufficient force in the Straits area to require an escort of certain ‘high profile’ vehicles across the Mackinac Bridge.

Examples of high profile vehicles include pickup trucks with campers; cars with small boats, bicycles or luggage attached to the roof; Ryder or U-Haul trucks; any vehicle pulling a boat; semi-tractors with enclosed trailers and all trailers with side walls over two feet in height. High profile vehicles must be escorted.

Motorists are asked to reduce their speed to 20 miles per hour as they approach the bridge and be prepared to stop. Bridge personnel are stationed at both ends of the structure to provide instructions regarding how and when to proceed across the bridge.

All vehicles must exercise appropriate caution. The Mackinac Bridge Authority is monitoring wind speeds at various points along the structure.
