About the Stoney Trail North interchange projects

North Calgary has continued to experience significant growth in population and traffic over the last few years with the existing communities north of Stoney Trail, including Nolan Hill, Sage Hill, Evanston and Sherwood Park, continuing to develop and expand. With the planned addition and development of the new communities of Carrington, Livingston, Keystone Hills and other developments in the area, further traffic stress will be added to the surrounding roadways and interchanges requiring improvements to the network in order to maintain traffic flows and support the development.

As approved in The City’s Investing in Mobility plan and the One Calgary 2019-2022 Service Plans and Budgets, The City is investing in improvements to multiple points of access along Stoney Trail. The Stoney Trail and 14 Street N.W. interchange is currently under construction with completion expected in summer 2021. This initiative will also include the upgrade of the existing Shaganappi Trail N.W. and Harvest Hills Blvd. interchanges on Stoney Trail and the construction of a new interchange at Stoney Trail and 11 Street N.E. This work is being done to support the Calgary Ring Road on behalf of Alberta Transportation.

All the Stoney Trail interchanges are being constructed within the Province’s Transportation Utility Corridor (TUC) and will be owned, operated and maintained by Alberta Transportation upon completion. The City of Calgary is constructing these interchanges on behalf of Alberta Transportation (AT), following AT standards and guidelines.

14 Street NW

Location: Stoney Trail and 14 Street N.W.

Description:

This intersection is being upgraded from the existing on and off access ramps to a new interchange that will connect the adjacent communities of Panorama Hills, Evanston, and Carrington.  In addition to maintaining free flow conditions along Stoney Trail, this interchange will be an important component in supporting the existing and future development in the area.

The new interchange is currently under construction and will utilize the existing ramps minimizing traffic impacts during construction.  The interchange includes a four-lane bridge structure on 14 Street N.W. over Stoney Trail, two new merge loop ramps onto Stoney Trail, and tear drop traffic circles instead of traffic signals on the north and south sides of the bridge.

See the project page for more details

Shaganappi Trail NW

Location: Stoney Trail and Shaganappi Trail NW

Description:

The existing interchange at Stoney Trail and Shaganappi Trail N.W. was constructed in 2006-2007 and is three lanes wide, with two lanes southbound and a single lane northbound. This project will upgrade the interchange by building a second three-lane bridge adjacent to the existing north-south bridge, providing three travel lanes in each direction once completed. The final interchange will provide a multi-use pathway which will connect to pathways on both the north and south sides of Stoney Trail.

In addition to upgrading the interchange, this project also includes an upgrade to the Shaganappi Trail/Hidden Valley Drive intersection to facilitate better access to and from the community.

See the project page for more details

Harvest Hills Blvd

Location: Stoney Trail and Harvest Hills Blvd

Description: The existing interchange was constructed in 2010 and is three lanes wide, with two lanes northbound and a single lane southbound. This project will upgrade the interchange by building a second three-lane bridge adjacent to the existing north-south bridge, providing three travel lanes in each direction once completed. For those wanting to walk or cycle across Stoney Trail, the final interchange will include a multi-use path which will connect to existing and future pathways.

See the project page for more details

11 Street NE

Location: Stoney Trail and 11 Street N.E.

Description: A new interchange is being designed in this location to support future development and to improve mobility and connectivity within north Calgary. Significant growth is anticipated in the Stoney Industrial and Keystone Hills areas immediately surrounding Stoney Trail and 11 Street N.E.

About the Calgary Ring Road

Calgary's Ring Road is located within The Province's Transportation Utility Corridor (TUC) and is operated and maintained by the Government of Alberta through Alberta Transportation.
