It is a heavily traveled commuter and truck bypass route, with the southwest quadrant serving as a portion of the critical CANAMEX Corridor linking Canada to the United States and Mexico. Traffic levels have quickly increased in recent years as sections of the road were completed, and it is now one of the busiest in Western Canada carrying over 105,000 vehicles per day at its busiest point in west Edmonton. The Calgary Trail/Gateway Boulevard interchange complex is designated as the starting point of the loop, with exit numbers increasing clockwise across the North Saskatchewan River to the Cameron Heights neighbourhood, then north past Whitemud Drive, Stony Plain Road and Yellowhead Trail to St. Albe
