Project overview

The West Calgary Ring Road, between Highway 8 and the Trans-Canada Highway, is the final 9 km of the Calgary Ring Road.

Most of the road will be built on the existing Transportation Utility Corridor owned by the Government of Alberta. Some additional small parcels of land will be purchased.

The West Calgary Ring Road project will be completed in 3 parts — the north project, south project and twinning of the bridge over the Bow River. It will include:

  • building about 9 km of 6- and 8-lane divided freeway
  • reconstructing about 5 km of the Trans-Canada Highway
  • widening Stoney Trail from the Bow River to Scenic Acres
  • 6 interchanges
  • 24 bridges

Once complete, the entire Calgary Ring Road will provide more than 101 km of free-flow travel around the city. It will improve access to hospitals, schools, workplaces and recreation, and help reduce congestion within the city.

North project

3 km of 6- and 8-lane divided freeway between Highway 1 (Trans-Canada Highway) and the Old Banff Coach Road.
