Enbridge announced that it will install more steel supports along the controversial Line 5 oil pipelines in the Straits of Mackinac.
Many have had concerns over the safety and integrity of the 60-year-old pipelines.
The U.S. Army Corps of Engineers approved the plan and permitting needed for installation.
According to a press release, the energy company says it will put 54 more supports along Line 5. Work is set to start immediately and should be finished later this week, according to Enbridge.
Enbridge has installed 147 supports on Line 5 since 2002.
Currently, Enbridge and Michigan's Attorney General are tangled in lawsuits over a long-term plan for the pipelines that carry propane and oil through the straits.
Line 5 sits on the lake bed of the straits, and Enbridge hopes to build a tunnel underneath the bedrock of the lake by 2024, but the tunnel project is currently on hold due to litigation.
Earlier this summer, Michigan Attorney General Dana Nessel filed a lawsuit to immediately close Line 5.
