Line 3 Replacement Project (U.S.)

Life takes energy—to heat our homes, to feed our families, to fuel our vehicles. Enbridge has been proudly fueling Minnesota's quality of life for 70 years.

The Line 3 Replacement Program, the largest project in Enbridge history, represents an improvement of our pipeline infrastructure—helping to ensure that Minnesota and the surrounding region are connected to secure, reliable and growing supplies of North American crude oil.

The $4-billion U.S. portion of the Line 3 Replacement Program, known as the Line 3 Replacement Project, consists of replacing existing 34-inch pipe with new 36-inch pipe for 13 miles in North Dakota, 337 miles in Minnesota, and 14 miles in Wisconsin. The Wisconsin portion was completed in 2018, while the North Dakota segment was completed in December 2020.

In December 2020, construction began on the 337-mile Minnesota portion of the project, the only segment of Line 3 yet to be replaced with new state-of-the-art pipe.

Enbridge’s private investment—$2.6 billion of it in Minnesota—will create well-paying jobs, an economic boost for local communities during construction, and local community investments and tax contributions for many years to come.
