The southwest portion of Anthony Henday Drive (SWAHD) is to be upgraded to a six-lane cross section, as part of design and construction efforts spanning more than 25 years to build the city of Edmonton’s ring road network. The project is divided in three stages as funds are allocated. The scope includes widening of the existing structures over the North Saskatchewan River and Wedgewood Creek, and expanding the interchange at Whitemud Drive. SWAHD connecting Whitemud Drive and Calgary Trail was the first quadrant of the ring road to be completed in 2006, prior to the full development of the ring road design guidelines used with the later P3 quadrants. Besides improving design consistency, adding two lanes will better serve the heavy traffic volumes that quickly exceeded the initially forecasted demand.
