Calgary's light rail transit (LRT) network of 38 LRT stations and 44km of track is extending west. Approved by Council in November 2007, the West LRT will extend the existing LRT line from downtown to 69th Street S.W. The eight-kilometre LRT line will feature six LRT stations, two Park and Ride lots and Calgary's first elevated and underground LRT stations. It will open for revenue service in December 2012.
