Stoney Trail North Interchange projects

Project updates - May 19, 2020

Construction is continuing on the Stoney Trail and 14 Street N.W. interchange. Upcoming work includes installation of storm lines, formwork, rebar and concrete pours for abutments and the centre pier, and earthworks.

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.

 

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.
