    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! Traffic peaks from 2-6 pm Friday can result in delays and traffic backups, even with all lanes open. Consider crossing at off-peak times. No-contact credit/debit cards transactions available; MacPass and phone payments are quicker.
