Ontario Highway 85

Ontario Highway 85

King's Highway 85, commonly referred to as Highway 85, is a provincially maintained highway in the Canadian province of Ontario. The 10-kilometre (6.2 mi) highway, which is mostly controlled-access, travels through the Regional Municipality of Waterloo along the Conestoga Parkway from its interchange with Highway 7 to immediately north of the Waterloo city limits, where it continues as Regional Road 85 to St. Jacobs.

Prior to completion of the Conestoga Parkway through Waterloo, Highway 85 followed King Street north of Ottawa Street through Kitchener and Waterloo. Within the City of Waterloo, this former alignment is now maintained by the region as Regional Road 15. Within the city of Kitchener, the road is simply known as King Street.
