the 17 Avenue SE / Blackfoot Trail / Deerfoot Trail interchange. The Highway 2A designation was phased out in the mid-1980s and the Barlow Trail between 48 Avenue NE (just north of McKnight Boulevard) and the main terminal access was closed to allow for additional runway construction. High River – Cayley The existing section of Highway 2A used extend from High River along 10 Street SE, through the hamlet of Cayley, and intersect Highway 2 at the locality of Connemara, located north of the town of Nanton along the Foothills County / Willow Creek M.D. boundary. The segment was located only west of Highway 2 and was lightly traveled, as such it was dropped by the province in 1997.
