Straits of Mackinac, Ontario





Enbridge’s Line 5 is 645 miles long stretching from Wisconsin across Michigan’s upper and lower peninsulas, terminating in Sarnia, Ontario, Canada. The 30” pipeline splits into two 20” pipelines for 4 ½ miles under the Straits of Mackinac (where Lake Michigan meets Lake Huron).  It also crosses under the St. Clair River.  Environmentalists are particularly concerned about the possibility of a spill in the Great Lakes.
