Interstate 75 runs 396 miles up Michigan, from the Ohio line below Detroit to the Canadian border at Sault Ste. Marie, and crosses both peninsulas by way of the Mackinac Bridge. The five-mile bridge closes to high-profile vehicles, and sometimes to everyone, when the wind gets up over the Straits — while the lake-effect snow belts north of Grayling can be measured in feet on a day Detroit stays dry.
