Southern segment edit

The southern section of Highway 21A was a 33 km (21 mi) highway which started at Highway 9 in the Village of Beiseker and traveled north for 13 km (8 mi) to the Village of Acme and then turned east for 20 km (12 mi) to Highway 21, 8 km (5 mi) northeast of the Village of Carbon.[1] It was established in 1958/59 when Highway 21 was realigned from Beiseker to Highway 1 (Trans-Canada Highway) east of Strathmore.[3][4] Highway 21A was renumbered to Highway 26 in 1962/63,[5][6] and in 1972/73 the north-south section became Highway 806 while the east-west section became Highway 575.[7][8]

Northern segment edit

The northern section of Highway 21A was a 5 km (3 mi) highway that connected Highway 21 with Highway 12 near the Hamlet of Nevis.[2] In the early-1990s, Highway 11 was extended east from Highway 815 near Joffre to Highway 21; when construction was completed, Highway 21A became part of Highway 11.[9][10]
