Stoney Trail North Interchange projects

Project updates - July 13, 2020

Temporary closures of eastbound and westbound Stoney Trail are scheduled from July 20 – 25 to accommodate the installation of bridge girders. The closures will be in effect during nighttime hours, from 10:00 p.m. to 5:00 a.m., with full access restored during the daytime.

Closures will be in place in the following areas:

  • Westbound Stoney Trail: between Harvest Hills Blvd. N. and 14 St. N.W.
    • Westbound Stoney Trail will be closed nightly from 10:00 p.m. until 5:00 a.m. from on Monday, July 20 to Wednesday, July 22
    • Traffic will be detoured south on Harvest Hills Blvd., west on Country Hills Blvd., and north on Beddington Tr. to access westbound Stoney Tr. See this map for details.

    • Eastbound Stoney Trail will be closed nightly from 10:00 p.m. until 5:00 a.m. from Thursday, July 23 to Saturday, July 25.
    • Traffic will be detoured south on Beddington Tr., east on Country Hills Blvd., and north on Harvest Hills Blvd. to access eastbound Stoney Tr. See this map for details.

Construction schedules may need to be adjusted based on unexpected weather conditions and construction progress. Closures may extend to Sunday, July 26 and Monday, July 27 if required.

Variable Message Boards (VMBs) will be posted in the area in advance of the scheduled closures, and detour signage will be on-site during construction.

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., along with a brand new interchange at 11 Street and Stoney Trail N.E.. Site assessments including survey and geotechnical investigations are currently underway at all three interchanges.

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 project will also include the upgrade of the existing Shaganappi Trail N.W. and Centre Street N. interchanges on Stoney Trail and the construction of a new interchange at Stoney Trail and 11 Street N.E.
