This project will make a safe pipeline even safer. "These approvals bring us a step closer to building the Great Lakes Tunnel," said Vern Yu, Enbridge Executive Vice President and President, Liquid Pipelines. "Line 5, encased in a tunnel below the lakebed, is the best way to safeguard the precious waters of the Great Lakes and ensures that low cost, safe and reliable energy keeps flowing to Michigan, neighboring states and Canada's two largest provinces."
