In 1953, we constructed what then was a state-of-the-art pipeline to transport oil by pipeline, rather than ship. To this day, Line 5 remains a sterling example of energy infrastructure that has stood the test of time to serve this region safely and well.

However, as with most major infrastructure — whether it be a highway, bridge or pipeline — it is time to look at options to help ensure such infrastructure can continue to meet safety and environmental needs while providing the region with much-needed energy well into the future.

With that in mind, Enbridge began working with the State of Michigan to determine feasible options for Line 5. The best option needed to advance safety and environmental protections without compromising the delivery of energy — on which area families and businesses rely.

Following extensive studies, we determined that construction of a tunnel to house a new Line 5 would be the best option. The State of Michigan recently approved the tunnel replacement project, which Enbridge will be paying to construct and operate.

A tunnel under the lakebed would reduce the likelihood of a release into the Straits of Mackinac and eliminate the chance of anchor strikes. It is the next logical step to making a safe pipeline even safer.

Every day, Michiganders count on the energy that’s safely delivered by Line 5. The pipeline carries products necessary to heat homes and power industry and the state’s economy. As shared often, more than half the state’s propane to heat homes and businesses is delivered from the Line 5 pipeline alone.

Line 5 is vital to the people of Michigan, and we feel a responsibility to ensure it can continue to serve this region well into the future. We look forward to continuing to work with the state on the next steps that will enable the region to continue to receive safe, reliable energy, while increasing environmental protection.
