King's Highway 77, commonly referred to as
Highway 77, is a
provincially maintained highway in the
Canadian province of
Ontario. One of three highways within
Essex County, Highway 77 serves to interconnect Highway 3 near
Leamington with Highway 401 near
Tilbury. Prior to 1998, the highway extended south into Leamington, ending at the former routing of Highway 3 and
Highway 18. This section was turned over to Essex County and renamed Erie Street. The speed limit on Highway 77 is in most places, dropping to 50 km/h in built-up areas. It is patrolled by the
Ontario Provincial Police.
