Ontario Highway 77

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 80 km/h (50 mph) in most places, dropping to 50 km/h in built-up areas. It is patrolled by the Ontario Provincial Police.

Route description

Due to the flat topography of Essex County, the land use surrounding Highway 77 is almost entirely agricultural. Soil conditions in Essex are ideal for farming, and as a result very few natural areas can be found in the county. Many streams have been diverted to irrigate the endless farmland to either side of the highway. Relief from the plain is provided only by the few hamlets along the route. In addition, Lake Erie and Lake St Clair are both a short distance from Highway 77.
