Demonstrating its commitment to safety, experience and the State of Michigan, US, Enbridge has selected two renowned and industry leading contractors for the Great Lakes tunnel project.

Michigan-based Great Lakes Tunnel Constructors will construct the tunnel to house a new Line 5 in the Straits.

Great Lakes Tunnel Constructors is a partnership between a Michigan tunnel construction firm, Jay Dee Contractors, Inc., and the US affiliate of Japanese tunnel construction firm, Obayashi Corporation.

Enbridge has also selected Arup, a leading engineering and consulting firm with large-scale infrastructure and tunnel design capabilities, to deliver construction design documentation for the Great Lakes Tunnel Project.

“The Great Lakes Tunnel Project is essential to Michigan’s economic vitality and long-term energy security,” said Brad Shamla, Vice President of US Operations at Enbridge. “It will enable residents, schools and businesses to continue to receive critical fuel and the thousands of products Line 5 helps make possible while increasing environmental safeguards and protection of the Great Lakes.”

Arup has extensive tunnel related experience; including design of the world’s highest pressure tunnel, design of the largest TBM constructed tunnel in the world, and numerous other river, lake and sea tunnel crossing designs involving a wide range of ground conditions.

Great Lakes Tunnel Constructors' project team has a collective track record of constructing over 400 pressurised-face tunnels consisting of more than 2.4 million ft of tunnelway. A number of those projects involved high pressure and ground condition parameters similar to those that will exist in the Straits of Mackinac.

“We are pleased to be part of the biggest infrastructure project in Michigan,” said Timothy Backers, Project Manager with the Great Lakes Tunnel Constructors. “We have worked successfully on some of the largest tunnel projects throughout the world, though there is an extra measure of pride in being selected to work on a project where we can make another vital contribution to our home state.”

Enbridge anticipates construction of the Great Lakes tunnel project will begin in 2021. Following approximately two years of construction, Enbridge expects to place the new Line 5 segment into service in 2024.
