Great Lakes Tunnel Information Center

Come visit us in St. Ignace, Michigan at 214 N. State Street

Enbridge’s Great Lakes Tunnel Information Center, located along the main street of St. Ignace on N. State Street, is open to the public. Inside you’ll find displays and information that help tell the story of how energy supports communities and is moved through the area. Giveaways and raffles for prizes pop up over the year as well, so be sure to ask about what’s scheduled next.

Join us May 7 for our grand reopening!

We’re excited to share our refreshed and expanded Great Lakes Tunnel Information Center. The center now includes a model of the Tunnel Boring Machine that will drill the tunnel. Representatives will be on hand to answer questions and provide the latest updates on the project.

Stop by to enjoy light refreshments, giveaways, conversation, and a fun new space on Wednesday, May 7, 2025 from 4 to 7 p.m. And while you’re here, please join our naming contest for the Tunnel Boring Machine.
