Since the 1970 ’ s , bringing an additional road network to Calgary and Edmonton has been identified as a provincial priority . In 2003 , construction of the provincial project officially began and the project has since been moving along sequentially around Calgary in four different quadrants . Starting in the west and moving to the east , the Northern half of the project is now complete and in 2009 , the third quadrant of the Calgary Ring Road project , the Southeast Stoney Trail ( SEST ), was commenced .
