Sign the Public Letter – Tell Regulators It’s Time to Grant Great Lakes Tunnel Permits

June 2, 2025

A public comment period has opened today for permits needed for construction of the Great Lakes Tunnel to begin.

Since the permitting process began 5 years ago, Enbridge has conducted more than 40,000 hours of survey work in the Straits, providing their results to permitters.  This has been one of the most comprehensive project reviews in Michigan’s history.

The Great Lakes Tunnel will be built safely, and what’s more, it will make an already safe Line 5 pipeline even safer by getting a portion of the line out of the water and into a tunnel deep below the lakebed.

It’s time to grant the permits and you can help! Click here to sign the public letter on our website to urge regulators to issue the necessary permits immediately. Thanks in advance!

DID YOU KNOW?
It would take 2,000 trucks or 80 railcars each day to transport the same volume of crude oil as Line 5. We must support Line 5 and advance the construction of the Great Lakes Tunnel.
