Highway 99A is a series of former highways in the southwestern part of British Columbia, Canada. It was the designation of the former 1942 alignment of Highway 99 as well a various alternate routes which existed in the 1950s and 1960s. The last official use of '99A' was decommissioned in 2006, although some present-day, commercially published road maps (such as Google Maps) still show it and some remnant signage still remains. Some brand new 99A signs can be seen as well as of 2023.
King George Highway / Kingsway
Highway 99A was long highway within Greater Vancouver and followed the original Highway 99 alignment between the Peace Arch Border Crossing and Downtown Vancouver and was designated in 1973 when the Deas (Island) Throughway was renamed Highway 99. Prior to that, the four-lane, divided "Deas (Island) Throughway" which was completed to the U.S. border in 1962, was designated Highway 499. Highway 99A was decommissioned by the province in 2006 and the city of Surrey renamed "King George Highway" to "King George Boulevard" in 2009, although, as of July 2021, the Ministry of Transportation keeps two minor segments of the former route maintained in its inventory.
