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 is underway.

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.

  • Reconstructing 5 km of Highway 1
  • 18 bridges
  • 2 interchanges
  • 1 flyover – 1 Avenue SW

South project

5 km of 6- and 8-lane divided freeway between Old Banff Coach Road and Highway 8.

  • 7 bridges
  • 4 interchanges
    • Old Banff Coach Road SW
    • Bow Trail SW
    • 17 Avenue SW
    • Highway 8

The Government of Alberta has selected three groups to submit proposals to develop the south section of the West Calgary Ring Road using a Design-Build delivery model. The submissions were evaluated based on several factors including experience, and past performance. The groups are consortia composed of construction and design companies.

  • Calgary Safelink Partners
  • EllisDon Construction Services Inc.
  • PCL Construction Management Inc.

Bow River Bridge twinning

  • Twinning the bridge over the Bow River on the northwest segment of the ring road
  • Widening about 2 km of northwest Stoney Trail from Crowchild Trail to Scenic Areas Link
  • The construction on the North West Stoney Trail corridor includes the addition of new collector/distributer roadway lanes between Crowchild Trail and Scenic Acres Link, and a bridge at Scenic Acres Link. This work is to accommodate southbound traffic entering Tuscany Boulevard or Scenic Acres Link and also includes minor reconfiguration of the westbound to southbound loop ramp at the Stoney Trail / Crowchild Trail interchange.

Tree removal for West Calgary Ring Road

Tree removal timing

In Calgary, the nesting window for migratory birds and other species that nest in the area extends from mid-April to late August each. If this work is not completed before the 2020 nesting season, these areas cannot be disturbed until fall 2020, resulting in the loss of a full construction season. This work must be completed at this time to ensure the West Calgary Ring Road (WCRR) remains on time to open October 1, 2022.

The tree removal areas have been identified based on the current plans and design submissions from the short-listed proponents. This allows Alberta Transportation to move the project forward and minimize tree removals. Only trees and brush in the areas required to build the new infrastructure will be removed.

Tree replanting

Trees will not be replanted adjacent to the WCRR due to ongoing maintenance requirements and potential future utilities. Areas disturbed by construction will be seeded with native grass mixtures when the project is complete.

Additional tree removal

If the contractor advises that additional trees need to be removed during construction, Alberta Transportation will review the request in accordance within provincial regulations and relevant legislation, modify as appropriate and notify impacted stakeholders when appropriate. This is a standard best practice when managing government infrastructure projects.
