Length	7.2 km (4.5 mi)

Highway 16A used to follow Baseline Road (101 Avenue), past Refinery Row, and linked with Highway 16 in Strathcona County. It began at the Edmonton city limits, located approximately 1.1 km (0.68 mi) east of the 50 Street intersection, and traveled east for 3.9 km (2.4 mi) to Highway 14X where it turned north for 3.3 km (2.1 mi) and terminated at Highway 16. In 1996, the province reverted the Baseline Road to Strathcona County while the north–south section became part of Highway 14X. Highway 14X was later renumbered Highway 216 in 1999, and signed as a part of Anthony Henday Drive in 2010.

Highway 16A
Location	Edmonton
Length	15.8 km (9.8 mi)
Existed	1980s

The Strathcona County segment of Highway 16A used to be part of a larger route which passed through central Edmonton, itself an original alignment of Highway 16. At the time, Highway 16 entered west Edmonton along Stony Plain Road and followed Mayfield Road, and Highway 16A originated at the intersection of Highway 16, Stony Plain Road, Mayfield Road. It travelled east along Stony Plain Road and 102 Avenue through the former town of Jasper Place for 5.3 km (3.3 mi) to 124 Street where it turned south for 150 m (490 ft) and then turned east onto Jasper Avenue for 3.9 km (2.4 mi), passing through Downtown Edmonton. At 95 Street, Highway 16A turned south for 170 m (560 ft) before turning east along Rowland Road for 1.7 km (1.1 mi) and crossing the North Saskatchewan River along the Dawson Bridge. East of 84 Street, Highway 16A followed 106 Avenue for 500 m (1,600 ft) to 79 Street (later using 84 Street), where it traveled south 900 m (3,000 ft) before turning east onto 101 Avenue and leaving Edmonton.

Highway 16A was phased out in the early 1980s.
