King Street, or Waterloo Regional Road 15, is the major northwest–southeast arterial road in Kitchener, Ontario, as well as Waterloo, Ontario, where it runs north–south. In Waterloo, King Street divides the city into east and west sides, and in Kitchener, it divides the city into north and south sides. At the Conestoga Parkway, in southern Kitchener, King Street becomes the Highway 8 Expressway. King Street "resumes" about four kilometres to the east, where Weber Street is renamed to King Street and then continues to Cambridge, Ontario.
