Enbridge receives permit, begins installing new support anchors in Straits of Mackinac

September 25, 2019

Enbridge has received a permit from the U.S. Army Corps of Engineers to install 54 steel supports along Line 5 in the Straits of Mackinac. We started work immediately and have completed the installation of a support at the span we identified to be measuring more than 75 feet.

Enbridge’s ongoing work to inspect, maintain and modernize its transport system ensures that Line 5 remains in top condition—keeping the environment safe and securing energy delivery to Michigan and the Great Lakes region. Ongoing inspections of the system will continue to guide the need for any additional anchors.

Since 2002 we have installed 147 supports on Line 5, and they have performed well in enhancing the safety of the Line.

Enbridge believes that the tunnel project is the best long-term solution for Line 5 moving forward. Placing the pipeline inside a tunnel, 100 feet below the lakebed, would eliminate any span issues, and the need for supports.
