In December of 2020, construction on a replacement pipeline began in Northern Minnesota in spite of protests from environmentalists and Native American groups whose land is crossed by the pipeline. A description of the pipeline was found on the Minnesota Government website:

“According to the owner, Enbridge Energy, Limited Partnership, the purpose of the Line 3 Pipeline Replacement Project is to replace the Minnesota portion of the existing Line 3 pipeline (built in the 1960s)  to: 1) address known integrity risks, 2) reduce apportionment due to decreased transport capacity related to integrity issues, and 3) restore flexibility to the Enbridge Mainline System for more efficient operation. The new Line 3 pipeline would have an annual average capacity of 760,000 barrels per day and would serve the same markets and transport the same products as the existing Line 3 pipeline.

Operationally, the new Line 3 pipeline would continue to transport crude from Canada to the Enbridge terminal facility in Clearbrook for subsequent delivery to Minnesota refineries via interconnected pipeline facilities operated by Minnesota Pipeline Company, and would deliver crude oil to the Superior Wisconsin terminal for subsequent delivery on the Enbridge Mainline System to refineries in the Midwest, Eastern Canada, and the Gulf Coast.”
