 It served as a portion of Alberta Highway 2 from the northern city limits to Blackfoot Trail, near the present location of the Max Bell Centre.At that point, Highway 2 followed Blackfoot Trail to 66 Avenue SE (present-day Glenmore Trail) before turning south on Macleod Trail, while Barlow Trail continued south along 26 Street SE.In the early 1970s, Highway 2 was diverted to the new freeway as part of the Blackfoot Trail Freeway (present-day Deerfoot Trail) construction, resulting in Barlow Trail becoming a rural road north of 112 Avenue NE (present-day Country Hills Boulevard) and being re-designated as Highway 2A.
