In 2009, five years of planning and negotiating for a ring road in Southwest Calgary was voted down by the members of the Tsuu T’ina (more here). When the province walked away from further discussions, they declared the Tsuu T’ina option dead and were anxious to move on; to develop another option entirely within the city of Calgary. This would be called the ‘Plan B’.
On November 27 2009, only five months after the rejection of a Tsuu T’ina alignment, the City of Calgary and the Province of Alberta signed a Memorandum of Understanding to jointly explore the 37th street SW corridor for the purposes of building an 8-lane freeway entirely within the city limits. The scope of the MoU was eventually expanded to consider alternative routes to 37th street SW, and the study was meant to conclude in the fourth quarter of 2011 with a proposed route.
Was there really no ‘Plan B’?
When the 2009 deal was initially defeated, then Mayor Dave Bronconier stated that they did not have a Plan B for the City and Province to fall back on.
Every transportation plan since 1959 planned for an extension of Sarcee Trail to become the primary north-south freeway on the west side of Calgary (essentially the ‘Plan A’). Though there have been a few alternatives proposed throughout the years, mainly involving on 37th street SW, these concepts had never been fully explored, and none have ever been approved (you can see these preliminary concepts here).
