Stoney Trail/Calgary Ring Road

The Government of Alberta approved construction of the next piece of Calgary’s ring road, currently named Stoney Trail, with construction on the southwest portion scheduled to begin in 2016. This next piece brings Calgary one step closer to completing the 100-kilometre, uninterrupted highway. As a city that moves, it improves the road network in and around Calgary.

Project update

Now that Council’s approved the West and Southwest Ring Road Downstream Traffic Impact report and we’re at the beginning of the year in which the Province plans to begin construction of Calgary’s southwest ring road, The City is beginning to coordinate and plan for its own work related to the ring road.

You can read more about the highlights of The City’s construction, design and planning work that’s currently underway or will begin in the next two years. This work is scheduled to be completed before The Government of Alberta opens the Southwest Calgary Ring Road, currently scheduled for fall 2021. As the projects move forward and more information is available, we’ll update you on where you can find the latest information.

Project objectives - The City of Calgary’s role

There are two things The City is carrying out before the Southwest piece of the ring road opens:

  • Design and construct roadways that connect the ring road with southwest Calgary.
  • Modify roads and intersections in Calgary’s southwest to make sure the ring road fits with Calgary’s road network. The modifications are based on the results and recommendations from Council’s direction to review the changes to traffic patterns and volumes on Calgary’s southwest roads when the ring road opens.

Review and learn more about the roads and intersections The City is constructing and modifying:

The Government of Alberta’s role

The Government of Alberta is responsible for the ring road highway, which is outside city limits:

  • Location and alignment
  • Interchanges
  • Connections to city limits
  • Bridges
  • Construction
  • Other items within the provincially owned Transportation Utility Corridor.

The Province is constructing the final ring road pieces as two projects:

  • Southwest Calgary Ring Road – Lott Creek Blvd on Highway 8. along Glenmore Trail, then south to Macleod Trail/22x Highway. Construction to begin in late 2016. Opening to traffic in late 2021.

  • West Calgary Ring Road - Bow River/Hwy 1 area to the 101 Street S.W./Highway 8 intersection (currently unfunded).
