Alberta Provincial Highway No. 2A is the designation of nine
alternate routes off
Highway 2 in
Alberta,
Canada. In general, these are original sections of
Highway 2, such as the southern portion of
Macleod Trail in
Calgary. They passed through communities before limited-access freeways were built to shorten driving distance, accommodate heavier volumes and to bypass city traffic. Portions of the alignment of Highway 2A follow the route of the former
Calgary and Edmonton Trail.
