Enbridge Inc. plans to replace Line 3, a 1,031-mile, 34-inch pipeline that has been in operation since 1968 and is one of six crude oil pipeline that comprise the its mainline system.
The decision came after Enbridge received shipper support for a $7 billion investment in its Canadian and U.S. mainline system running from Edmonton, Alberta to Superior, WI. The Line 3 Replacement (L3R) program will complement the existing Line 3 segment replacement program and include all remaining segments of Line 3 between Hardisty, Alberta and Superior.
The L3R program is targeted for completion in the second half of 2017. Initial development work is underway to support the regulatory applications that will be submitted in later this year.
