A project critical to protecting the environment and the longterm viability of Enbridge Line 5, a crude oil pipeline that supplies refineries throughout the midwest, is in jeopardy.

The Enbridge Straits Line 5 Replacement Segment Project would allow for the current pipeline that runs through the Straits of Mackinac to be rerouted through a tunnel in the bedrock beneath the Straits, protecting the waterway and the Great Lakes.
