How would the Great Lakes Tunnel protect the Great Lakes?

Our Answer

The Great Lakes Tunnel will completely encase a newly constructed Line 5 pipeline in a thick layer of concrete far below the lakebed, allowing for the decommissioning and removal of the existing line off the lakebed surface.

It’s vital infrastructure that will protect our precious waterways, fish and wildlife by ensuring nothing can damage the pipeline. What’s more, the tunnel will help give safety workers and inspectors better access to the line, so they can monitor and maintain it most effectively.
