On October 3, Michigan Governor Rick Snyder signed an agreement with Enbridge Energy to decommission the Line 5 petroleum pipeline segment that crosses the Straits of Mackinac and construct a new multi-use utility tunnel underneath the Straits. The newly constructed tunnel will replace aging critical energy infrastructure and guarantees major safety enhancements along the entire length of the Line 5 pipeline throughout the state. Per the agreement terms, Enbridge would be responsible for the estimated $350-500 million in design and construction tunnel costs as well as up to 99 years of tunnel operation and maintenance costs subject to approvals by the Mackinac Bridge Authority.
