Motorists celebrate Southeast Stoney Trail opening

For the first time, motorists can drive 70 kilometres of free-flowing freeway on the Calgary Ring Road with today’s opening of Southeast Stoney Trail.

East-west portions of the freeway will officially open when Stoney Trail opens to traffic late this afternoon. Interchanges along the brand-new north-south stretch of the freeway will open in a domino fashion in both directions so as to maximize the safety of travellers.

Opening schedule

Interchanges along the brand new section of the freeway will open in a safe, staged manner with the entire road expected to be open by late afternoon. The speed limit along this section will be 100 kilometres per hour. Drivers are reminded to obey all signs and signals.

The first southbound interchange to open will be:

  • Highway 22X/Stony Trail and 88 Street SE., followed by
  • 114 Avenue,
  • Glenmore Trail and finally
  • Peigan Trail.

The first northbound interchange to open will be:

  • Glenmore Trail SE., followed by
  • 114st Avenue SE, and finally
  • Highway 22X/Stony Trail and 88 Street SE.
  • Peigan Trail opened to northbound traffic earlier this year as part of construction.

17 Avenue SE will continue to be open as it has been during the last few weeks of construction.

Travellers have access to the completed interchanges along the east-west section of SE Stoney Trail and will notice an increase in the speed limit. Interchanges along this section, formerly known as Marquis of Lorne Trail and Highway 22X, are:

  • 52 Street SE
  • Deerfoot Trail SE,
  • McKenzie/Cranston Boulevards, and
  • Sun Valley/Chapparal Boulevards.

By rush hour motorists will have access to all 70 kilometres of free-flowing travel.

More safety information

  • The speed limit on Stoney Trail southeast is 100km/h, with reduced posted speed limits for on and off-ramps.
  • Motorists are cautioned to watch for new directional signage and reduce speed while adjusting to new traffic patterns. Motorists should drive to winter conditions.
  • Drivers may also see some ongoing finishing touches along the Southeast Stoney Trail route as the contractor has one year to complete construction details. This work includes primarily off-street activity such as area restoration, finishing work and grass-seeding.

More information about construction completion, and operations and maintenance is available on the Southeast Stoney Trail website at

Additional information

Alberta Transportation and the Chinook Roads Partnership would like to thank all motorists for their patience as this newest section of Calgary’s ring road was being built.

Southeast Stoney Trail is a $769 million P3 project for the construction and the 30-year maintenance of 25 kilometres of six-lane roadway including:

  • nine interchanges;
  • 27 bridge structures; and
  • three flyovers.

The P3 contract also involves the maintenance of 12 kilometres of Deerfoot Trail between Stoney Trail SE (currently Highway 22X) and the Highway 2A junction.

The Government of Alberta has invested $1.9 billion in Calgary’s ring road, one of many projects that deliver on the government’s commitment to building Alberta. By focusing capital plan projects on core infrastructure and key corridors, the Alberta government continues to develop the province’s economy while expanding market access.
