Stoney Trail and 14 St N.W. interchange project

Project update: September 2019

Crews will be on site this month to start construction on the Stoney Trail and 14 Street NW interchange. Crews will start with earthworks, and construction on the interchange abutments until the site shuts down for the winter. We don't expect there to be any impacts to the existing ramps at Stoney Trail and 14 Street while crews are working this fall.

The anticipated construction completion is the summer of 2021.

 

About the project

Northwest Calgary (Panorama Hills and Evanston) has experienced significant population and traffic growth over the last few years. With these new developments, many of these communities access Stoney Trail and other parts of the city via four on and off ramps at 14 Street N.W. and interchanges at Beddington Trail N.W. and Centre Street/Harvest Hills Boulevard North.

The Stoney Trail and 14 Street NW interchange is a missing link to Stoney Trail between Beddington Trail N.W. and Centre Street/Harvest Hills Blvd N interchanges.

As part of the One Calgary budget, approved by City Council in 2018, The City of Calgary allocated funding to construct a number of interchanges along Stoney Trail NW. The first to move forward this summer is the Stoney Trail and 14 Street NW interchange.

Project Scope

The interchange will include:

  • Four-lane 14 Street N.W. bridge over Stoney Trail.
  • Northbound to westbound Stoney Trail and southbound to eastbound Stoney Trail on ramps.
  • Westbound to southbound 14 Street and eastbound to northbound 14 Street off ramps.
  • Two merge loops onto Stoney Trail.
  • A direct route for drivers between existing and future communities.
  • Tear drop traffic circles, instead of traffic signals on the north and south sides of the bridge.
  • Asphalt pathways and concrete sidewalks on the east and west side of the new interchange.
