King's Highway 2A -

Highway 2A existed within the City of Toronto until 1997 as a short expressway stub between the Lawson Boulevard interchange and Highway 401 at Port Union Road.  It was shortly over three kilometers long when it was transferred to Metropolitan Toronto.  Despite its short length, Highway 2A has a distinguished history.  Highway 2A was the initial name for what has become Highway 401 between Lawson Road (Highland Creek) in Scarborough and Ritson Road in Oshawa.  Prior to Highway 2A, when a stretch of dual highway was opened to traffic in Ontario, the existing arterial highway had always simply been twinned on an existing alignment.  Highway 2A was different as, while it served the purpose of a twinned Highway 2, Highway 2A was constructed entirely upon its own alignment.  This created a numbering conundrum that was unique to Ontario at that time.  The decision was designate the new highway as an Alternate routing of Highway 2, hence 2A.  Later, in 1952, it was decided that all new dual-highways should be designated as 400-series highways to distinguish the freeway network from the arterial highway network.  In the 1950s a short segment of the original  Scarborough to Oshawa highway was by-passed by the Toronto Interceptor Road section of Highway 401 and with that, the short anomalous Highway 2A designation was retained.  Since being downloaded, the City of Toronto has maintained 'Highway 2A' as the freeways proper name.
