context_page_description: Alberta Provincial Highway No. 201, officially named Stoney Trail and Tsuut'ina Trail, is a 70-kilometre freeway in Calgary, Alberta. Planned for a total length of 101 kilometres, three final segments of the ring road are currently under construction to be incrementally completed by 2024 at the latest, delayed from an original target of 2022. The freeway serves as a bypass for the congested routes of 16 Avenue N and Deerfoot Trail through Calgary. At its busiest point near Beddington Trail in north Calgary, the six-lane freeway carried nearly 79,000 vehicles per day in 2019.
  Stoney Trail begins in the city's northwest at Highway 1 near Canada Olympic Park, running north across the Bow River and Crowchild Trail. It winds through the hills of northwest Calgary to Deerfoot Trail and the Queen Elizabeth II Highway. Turning south, the freeway again intersects Highway 1, crosses Glenmore Trail, and curves west at the neighbourhood of Mahogany. Beyond a second major interchange with Deerfoot Trail, it descends across the Bow River and ends at Macleod Trail in the city's southeast.
context_section_description: On March 2, 2009, the Alberta Government announced the proceeding with construction of the remaining portion of the East Freeway from 17 Avenue SE to Highway 22X, as well as improvements to the existing Highway 22X roadway between that location and just east of the Macleod Trail (Highway 2A) interchange. This portion, like the northeastern portion, was built as a P3.  Three firms bid on the contract: Chinook Partnership, SEConnect and SE Calgary Connector Group.  The winning bid of $769 million was submitted by Chinook Roads Partnership.  Chinook Roads Partnership will also be responsible for maintenance of this portion of the Ring Road, as well as maintenance of Deerfoot Trail between Highway 22X and Highway 2A for 30 years after construction completion.
  Construction on the southeast leg began in the spring of 2010, and was opened on November 22, 2013, almost two months behind schedule. The southeast extension of Stoney Trail also resulted in upgrades to Highway 22X between Stoney and Macleod Trails.  When the extension opened in 2013, the City officially renamed this portion of 22X as part of Stoney Trail, and the province designated it as part of Highway 201.  Highway 22X continues west of Macleod Trail as Spruce Meadows Trail, while 22X continues east of Stoney Trail toward Gleichen.
  An interchange was constructed at Sun Valley Boulevard / Chaparral Boulevard, upgraded from the existing intersection.  The original project schedule from June 2010 had interchange construction starting in 2010 with construction of the bridge structure in 2011 towards a phased opening in 2012-2013.
  The McKenzie Lake Boulevard / Cranston Boulevard intersection was upgraded to a modified diamond interchange; work on this interchange began 2010 and by fall 2011 the bridge structure had been erected. The interchange design is a modified diamond and integrates into the nearby cloverstack interchange at Deerfoot Trail.
  Some residents of the Cranston neighbourhood were unhappy with the design of the interchange, as access was removed from westbound Stoney Trail to the interchange or the Cranston Avenue / Seton Boulevard interchange on Deerfoot Trail.  Access was also removed Commuters also cannot go on to the ramp to Deerfoot Trail southbound and can go only northbound when on the ramp to the highway. The commuters are forced to use the 52 Street interchange to the east. As for the commuters heading to northbound Deerfoot, they have to head to the McKenzie Towne / McKenzie Lake Boulevard interchange or the Seton Boulevard / Cranston Avenue interchange, which both lead to Deerfoot Trail northbound.
  A partial cloverleaf interchange was constructed at 52 Street SE.  The original project schedule from June 2010 had this interchange fully opening in the fall of 2013 with traffic on the new structure in the summer of 2012 with construction starting in 2011.  The revised project schedule of June 2011 still indicated a fall 2013 opening, the only significant difference is the temporary constructions detour road has been shifted to the east side of the bridge structure from the west side.  As of December 2011, construction of the interchange had started with grading of the interchange ramps and piling installation. 52 Street interchange was completed with the rest of the project on November 22, 2013. At 88 Street SE, Stoney Trail intersects with 22X with a hybrid interchange.  An existing intersection at 88 Street SE was removed.  Grading was also completed for a future interchange at 130 Avenue. A similar partial cloverleaf interchange was constructed at a slightly realigned 114 Avenue SE. The interchange fully opened on November 22, 2013.
  Partial cloverleaf interchanges were constructed at Glenmore and Peigan Trails.  Peigan Trail was also be extended from 52 Street to Stoney Trail as a result. The existing 17 Avenue SE intersection, which had been the terminus of the freeway since 2009, was upgraded to a partial cloverleaf interchange.
  In the fall of 2011, the province held a community consultation meeting on upgrading the Macleod Trail / 22X interch
