steeles

Steeles Avenue is an east–west street that forms the northern city limit of Toronto and the southern limit of York Region in Ontario, Canada. It stretches 77.3 km (48.0 mi) across the western and central Greater Toronto Area from Appleby Line in Milton in the west to the Toronto-Pickering city limits in the east, where it continues east into Durham Region as Taunton Road, which itself extends 58 km (36 mi) across the length of Durham Region to its boundary with Northumberland County.
York Region refers to Steeles Avenue as Regional Road 95 but the designation is strictly internal and there are no signs posted; as the street was always owned and maintained by the City of Toronto (succeeding Metropolitan Toronto). Through Peel and Halton Regions, the street is signed as Peel Road 15 and Halton Road 8, respectively.
The combination of Steeles and Taunton Road is the only arterial road to cross almost the entire Greater Toronto Area without breaks or turnoffs.
