Line 3 Replacement (L3R) Program
The $7.5-billion Line 3 Replacement (L3R) 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 will complement the existing Line 3 segment replacement program, and 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.
