Line 3 Replacement Program

The $7.5-billion Line 3 Replacement Program is the largest project in Enbridge history, and includes replacing the existing pipe with modern pipe materials utilizing modern construction methods -- resulting in restoration of one of Enbridge's primary pipelines along its Mainline crude oil system.

The Line 3 Replacement Program 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.
