• Funding for the West Calgary Ring Road was announced on July 5, 2018. Once complete, the road will provide 101 km of free-flow traffic.

Project overview

The West Calgary Ring Road, running between Highway 8 and the Trans-Canada Highway, is the final section of the Calgary Ring Road to be completed.

The road will be built on the existing Transportation Utility Corridor, established in 1976. The land is 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 (DB1), south project (DB2) and the West Bow River bridge (WBRB). It will include:

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

On March 5, 2019, contracts were awarded for DB1 ($463 million) and WBRB ($89 million). Construction will begin this spring.

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.
