The proposed Alberta Clipper project is a new 1,607 km oil pipeline from Hardisty, Alberta to Superior, Wisconsin. The Canadian portion of the project would involve the construction and operation of facilities including approximately 1,074 km of new 914 mm outside diameter (36-inch) oil pipeline between Enbridge's Hardisty Terminal and the Canada-United States border near Gretna, Manitoba. The pipeline would have an initial capacity of 71,500 m3 (450,000 barrels per day).

The estimated cost of the project is expected to be $2 billion with construction to be completed by the end of December 2009.
