The multibillion-dollar Line 3 Replacement Program is the largest project in Enbridge history. The new Line 3 will comprise the newest and most advanced pipeline technology—and provide much needed incremental capacity to support Canadian crude oil production growth, and U.S. and Canadian refinery demand..
The Line 3 Replacement Program, with a C$5.3-billion Canadian component and a US$2.9-billion American component, expands on the former Line 3 Segment Replacement Program, and will include all remaining segments of Line 3 between Hardisty, Alberta and Superior, Wisconsin. All told, the Line 3 Replacement Program will fully replace 1,031 miles (1,660 kilometres) of Line 3 with new pipeline and associated facilities on either side of the Canada-U.S. international border.
The largest project in Enbridge history proposes to replace all remaining segments of Line 3 from Hardisty, AB to Superior, WI.
