Ontario provincial highway 6 is one of the King's Highways in the province of Ontario, Canada. It covers some 480 km, from Port Dover on Lake Erie, through Hamilton, Guelph, Owen Sound and Tobermory.
At Tobermory, the Chi-Cheemaun ferry crosses Lake Huron, docking at South Baymouth. Highway 6 resumes at South Baymouth and traverses Manitoulin Island to Little Current, where it crosses the north channel of Lake Huron by a swing bridge. Once on the mainland, the highway continues to north of Espanola, where it ends at the Trans-Canada Highway (Highway 17).
In Guelph, it travels the full length of the Hanlon Parkway, and it travels part of the Lincoln M. Alexander Parkway in Hamilton. However, a new highway routing is under construction in Hamilton to separate Highway 6's through traffic from the city's expressway traffic on the Parkway.
It is located at the junction of Highway 3, at Highway 24, due south of Brantford, Ontario, and accessible to Hamilton by nearby Ontarioprovincialhighway6.
It was named after the first Lieutenant governor of Upper Canada (Ontario), John Graves Simcoe; The community of Simcoe should not be confused with Simcoe County, located on the north shore of Lake Simcoe, of the many places he is named after in Ontario.
Growth in the town continues at a slow pace, although the addition of a new Toyota parts plant is expected to accelerate that.
It lies at the western end of the heavily populated Quebec City-Windsor Corridor, is the second largest city in Southwestern Ontario, and is the seat of Essex County.
Windsor is the western terminus of both OntarioHighway 401, Canada's busiest highway, and of VIA Rail's Quebec City-Windsor Corridor.
On November 14, 2005, the joint Canadian-American committee studying the options for expanding the border crossing announced that its preferred option was to directly extend Highway 401 westward, using a new bridge or tunnel to cross the Detroit River and interchange with Interstate 75 somewhere between the existing Ambassador Bridge span and Wyandotte.
