Line 3 Replacement Project approaches major milestone

With construction now nearly 50% complete, the project is on track for completion in late 2021

March 11, 2021

The Line 3 Replacement Project is approaching a major milestone, with nearly 50% of construction complete overall. Soon, due to seasonal and environmental restrictions, work on the Line 3 Replacement Project will pause for most pipeline construction activities for approximately two months beginning April 1. Construction will continue at the eight Line 3 pump station facilities.

“Winter construction has gone very well, and the project is on track for completion late this year,” said Barry Simonson Director of Line 3 mainline construction. “This is a planned two-month hiatus and most pipeline workers will begin coming back to the project in May, with construction restarting on or around June 1. Depending on the type of work they do, some workers may move on to other projects. Others are using this time to be with their families.”

“Facilities construction will continue on the project’s pump stations during this time,” said Randy Rice Director of Line 3 facilities construction. “We have been moving the last of our control buildings into place, and work at all eight pump station facilities is either on or ahead of schedule.”

World-class environmental protections developed through the permitting process inform the project’s plan. Crews continue to work on trenching, coating, stringing, welding, lowering and backfilling, as well as stabilizing construction areas in anticipation of the spring hiatus. Once work resumes, summer and fall plans will include final phases of construction and restoration.

For the past three months, replacing Line 3 has provided critical economic benefits for northern Minnesota counties, small businesses, Native American communities, and union members—including creating 5,200 family-sustaining construction jobs, and millions of dollars in local spending and tax revenue.

The Line 3 Replacement Project is the most studied and approved pipeline project in Minnesota history. This safety and maintenance focused upgrade to existing energy infrastructure will better protect Minnesota’s environment for generations to come.
