Kingston Road is a major arterial road in Toronto and Durham Region, Ontario. It the southernmost major (mainly) east-west road in the eastern portion of Toronto, specifically in the district of Scarborough, and runs east to Ajax in Durham. Until 1998, it formed a portion of Highway 2. The name of the street is derived from Kingston, Ontario as the road was the primary route used to travel from Toronto to the settlements east of it situated along the shores of Lake Ontario; in the west end of Kingston, the road was referred to as the York Road (referring to Toronto) until at least 1908, and is today named Princess Street. Due to its diagonal course near the shore of Lake Ontario, the street is the terminus of many arterial roads in eastern Toronto, both east–west and north-south, with a few continuing for a short distance after as minor residential streets. However Lawrence Avenue continues as a major arterial for a considerable distance beyond it. The road no longer bears the name "Kingston Road" anywhere east of Ajax, and thus has effectively been dramatically shortened from its original length. This is in contrast to other long-distance historic "streets" such as Dundas Street, which runs from Toronto to London and still carries that name in the latter city and in many points in between. History American engineer Asa Danforth Jr. was contracted to build a road as a route to connect Toronto (then called York) with the mouth of the Trent River in 1799 at a cost of $90.00 per mile. The road, known as The Scarborough Front Road, was completed by December 18, 1800, but was poorly maintained thereafter. In 1815 the Kingston Road was surveyed and it followed the line, in many cases, of the former road laid out by Asa Danforth as far as the Trent River. Beyond that point, the two historic roads diverge. The Kingston Road was completed in 1817, serving as a post road for stagecoaches delivering mail. Route description The Toronto section runs from Queen Street East, as a continuation of Eastern Avenue, just west of Woodbine Avenue (route to Lake Shore Boulevard, the westerly continuation of former Highway 2), through Scarborough to Toronto's eastern city limits with Durham Region, where it continues into Pickering and Ajax (as Durham Regional Highway 2), and officially ends where its name changes to Dundas Street in Whitby,
