About: Ontario Highway 39

King's Highway 39, commonly referred to as Highway 39, was a provincially maintained highway in the Canadian province of Ontario. The 33.8-kilometre (21.0 mi)-long route connected Highway 3 in downtown Windsor with Highway 2 south of Belle River, travelling along the southern shoreline of Lake St. Clair. Highway 39 was established in 1934. By 1961, the Pike Creek Bypass was opened and Highway 39 was rerouted along it, with the former route briefly becoming Highway 39B. The route was renumbered as Highway 2 in 1970, retiring the designation from the provincial highway system. Highway 2 was itself decommissioned along the former route of Highway 39 on January 1, 1998, and transferred to Essex County and the City of Windsor. It was subsequently redesignated as Essex County Road 22.
