    News & Events

    Windy conditions (20-34mph) at the #MackinacBridge could affect high-profile vehicles (pickup trucks w/campers, motor homes, vehicles pulling trailers, enclosed semi-truck trailers). Reduce speed to 20mph max, turn on 4-way flashers & use outside lane.

    Patience, please! Southbound traffic peaks from 10 am-4 pm Sunday can result in traffic backups, even with all lanes open. Consider crossing at off-peak times. Cash, MacPass, tap-to-pay cards are quickest, along with Apple Pay/Google Pay
