August 26, 2025 – The deadline for public input on Enbridge’s Line 5 project is ending Friday, with two sides of the issue stating support and opposition.
The Michigan Department of Environment, Great Lakes and Energy is currently reviewing Enbridge Energy’s Line 5 tunnel project at the Straits of Mackinac.
The project would see Line 5 replaced with a new tunnel running four miles along the Mackinac Straits. It would bury the line underground and include a concrete liner that’s one foot thick.
