Line 3 Replacement Program (Canada)Return to project
Enbridge’s existing Line 3 pipeline, which has been in service since 1968, runs from Edmonton, Alberta to Superior, Wisconsin. The Line 3 Replacement Program will replace the majority of the existing 34-inch-diameter pipeline with a 36-inch-diameter pipeline from Hardisty to Gretna on the Canadian side, and from Neche, N.D., to Superior on the U.S. side. Segments of Line 3 from the Canadian border to Neche, N.D., and near the Minnesota-Wisconsin border to the Superior terminal, are being replaced under separate segment replacement projects. The total length of pipeline replacement is 1,031 miles (1,660 kilometres).
