Calgary ring road now offers 70 km of free-flow traffic

The newest section of Stoney Trail in Calgary’s southeast opened Friday, November 22, bringing relief to drivers from the city’s southern quadrant, travellers heading into and around the city and commercial motorists moving goods to markets. Albertans can now take the Calgary Ring Road from Macleod Trail on the city’s south side, along the eastern border and around the north connecting with Highway 1 toward Banff.

Southeast Stoney Trail is a six-lane freeway which runs from 17 Avenue SE to just east of Macleod Trail, a distance of 25 kilometres, with:

  • nine interchanges,
  • 27 bridges,
  • one road flyover, and
  • two rail flyovers.

In all, Stoney Trail now offers 70 kilometres of free-flowing travel, a $1.9 billion total investment in Alberta’s core transportation network. SE Stoney Trail is the second largest highway project in Alberta’s history in terms of scope, a $769 million public private partnership (P3), including $100 million from the Government of Canada. The contract includes a 30-year maintenance agreement on this leg, as well as a 12-kilometre stretch of Deerfoot Trail.

This section opens just weeks after the Tsuu T’ina Nation and the Government of Alberta reached a historic tentative agreement to develop the final leg of the Calgary ring road in the city’s southwest.


A vital part of the provincial highway network which will improve market access, Stoney Trail supports Alberta’s vision to provide safe, accessible, free-flowing travel. Opening this section helps ensure improved travel and less congestion for individual and commercial users both within Calgary and across the region. Under the Building Alberta Plan, our government is investing in families and communities, living within our means, and opening new markets for Alberta's resources to ensure we're able to fund the services Albertans told us matter most to them. We will continue to deliver the responsible change Albertans voted for.
