The Straits of Mackinac, where Lake Huron and Lake Michigan meet, support recreation, commerce and a Michigan way of life.

The Straits are a natural treasure—a place worth protecting. That's why we take special precautions with our dual Line 5 pipelines—which travel a distance of 4.5 miles along the bottom of the Straits—to protect this resource.
