Southwest Calgary Ring Road Project


The Government of Alberta is responsible for the design, construction, management and operation of Calgary’s Ring Road.

The Southwest Ring Road (SWRR) is entirely within the Provincially-owned Transportation Utility Corridor (TUC). The TUC is designed to house the Calgary Ring Road system, major power lines, pipelines, regional water and sewer lines, and telecommunication lines and it is owned and operated by the Province of Alberta.

For information on the SWRR, including information related to the history of Calgary’s ring road or its design please contact Alberta Transportation directly at: trans.contact.us.m@gov.ab.ca.

Southwest Ring Road design and construction

KGL Constructors is responsible for the design and construction of the SWRR. KGL began construction in early 2017 and the SWRR is expected to be open to traffic in 2021.

For more information on the construction of the SWRR, KGL's webpage contains information on construction, alignment maps and traffic detours.

If you have additional inquiries or questions, please contact KGL Constructors by e-mail: info@swcrrproject.com or 24/7 phone: 403-212-0565.

Take a virtual tour of the SWRR with this Government of Alberta animated fly-by, where you’ll see the general location of this new section of the ring road and planned interchanges.




City of Calgary street connections and road improvements

The City of Calgary will also begin work to extend streets to connect Calgary’s road network to the ring road, while improving some existing roads to make sure the SWRR fits with our city's road network. The links below provide information on all the City-led projects including streets connections to the SWRR, road improvements and intersection improvements.
