Stoney Trail North Interchange projects
Project updates - November 19, 2020
Stoney Trail / 14 Street N.W. interchange
Stage 1 and 2 concrete deck pours are now complete. The existing eastbound Stoney Trail to southbound 14 Street N.W. and northbound 14 Street to eastbound Stoney Trail N.W. ramps will be paved before the construction site shuts down for winter. Construction will resume in Spring 2021.
- On Monday November 23 and Tuesday November 24 from 10:00 PM until 5:00 AM, two lanes on westbound Stoney Trail at 14 Street N.W. will be closed to accommodate the removal of bridge tarps.
- On Wednesday November 25 and Thursday November 26 from 10:00 PM until 5:00 AM, two lanes on eastbound Stoney Trail at 14 Street N.W. will be closed to accommodate the removal of bridge tarps.
Work will be done weather permitting.
Stoney Trail / Shaganappi Trail N.W., Stoney Trail / Harvest Hills Boulevard N., and Stoney Trail / 11 Street N.E. interchanges
Detailed design work is currently underway for improvements on two other North Stoney Trail interchanges at Shaganappi Trail and Stoney Trail N.W. and at Centre Street / Harvest Hills Boulevard and Stoney Trail N., as well as on a brand-new interchange at 11 Street N.E. and Stoney Trail.

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.
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.
A new asphalt pathway and concrete sidewalk on the east and west side of the interchange will also improve pedestrian and cyclist connections in the area.
Construction timeline: summer 2019 - summer 2021
Project update: Bridge deck rebar and formwork are ongoing with concrete deck pours planned over the next few weeks.
The existing eastbound Stoney Trail to southbound 14 Street N.W. and northbound 14 Street to eastbound Stoney Trail N.W. ramps have been milled and will be paved over the next couple of weeks.
- Reduced speed limit (80 km/hr) in construction zone on Stoney Trail when workers are present
- Occasional traffic restrictions/lane closures in construction zone on Stoney Trail
Other Stoney Trail North Interchanges
Shaganappi Trail NW
Location: Stoney Trail and Shaganappi Trail NW
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.
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.
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. The northwest, northeast, and southeast sections of the Ring Road (Stoney Trail) are completed and in use. Construction on the southwest and west sections are currently underway.
When the Calgary Ring Road is complete, it will provide 101 kilometers of free-flow travel around Calgary and contribute to safe and easy movement of goods and people in and around the city.
