Elbow River bridge crossing

The Southwest Ring Road (SWRR) includes the construction of a highway bridge crossing over the Elbow River. This crossing is within the Transportation Utility Corridor (TUC), upstream of Weaselhead Park and The City's Glenmore Reservoir. Some concerns were raised on the bridge design. Alberta Transportation and KGL Constructors have posted a notice on this issue and more information is available on KGL's website, under the August 2017 updates.

The City has also created an FAQ document to help answer some of the commonly asked questions about the Elbow River bridge and its design.

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 late 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: or 24/7 phone: 403-212-0565.

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

The SWRR is entirely within the Provincially-owned 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.

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.
