The Great Lakes Tunnel will be a utility corridor to connect Michigan’s peninsulas. It will carry the Line 5 pipeline light crude oil and natural gas liquids as it crosses under the lakebed at the Straits. Enbridge said the bored tunnel could also be used to house other utilities.
“This agreement with Barnard and CBNA marks a milestone for this historic project. The selection of these two world-class companies reinforces our commitment to safely building the Great Lakes Tunnel,” said Tom Schwartz, senior vice-president liquids pipelines, Enbridge Strategic Projects and Partnerships.
Barnard and CBNA will each retain a 50% partnership under the name Mackinac Straits Partners.
Enbridge is preparing to begin construction once it receives environmental permits from the US Army Corps of Engineers, which could be early 2026.
