King's Highway 6, commonly referred to as Highway 6, is a provincially maintained highway in the Canadian province of Ontario. It crosses a distance of between Port Dover, on the northern shore of Lake Erie, and Espanola, on the northern shore of Lake Huron, before ending at the Trans-Canada Highway (Highway 17) in McKerrow. Highway 6 was one of several routes established when Ontario first introduced a highway network on February 26, 1920, following several pioneer wagon trails. The original designation, not numbered until 1925, connected Port Dover with Owen Sound via Hamilton and Guelph. When the Department of Highways (DHO) took over the Department of Northern Development (DND) in 1937, Highway 6 was extended north through the Bruce Peninsula to Tobermory. In 1980, the entire length of Highway 68 on Manitoulin Island and north to Highway 17 became a northern extension of Highway 6. Small modifications were made to the route of Highway 6 in 1997, but it was largely untouched by provincial downloading. Highway 6 is one of two highways in Ontario (the other being Highway 33) broken into two segments by a ferry. The Chi-Cheemaun ferry serves automobile traffic, connecting Tobermory with South Baymouth between May and October. Route description Port Dover to Hamilton Highway 6 begins at Saint Patrick Street in the community of Port Dover, and stretches northward as a two-lane, undivided highway. The road travels into Haldimand County, through communities such as Jarvis and Hagersville, and the traffic flow increases. At Caledonia, the road bypasses the former Highway 6 section (Argyle Street) that passes the town centre of Caledonia and is routed outside the urban area Caledonia. This Caledonia Bypass was opened in 1983, and is a two-lane undivided freeway. The bypass terminates at Green's Road on the north side of Caledonia and Highway 6 proceeds eastbound on Green's Road for approximately 500 metres to Argyle St. North. Highway 6 then turns north on a four-lane undivided alignment for 5 km. Much of the old alignment north to near Rymal Road remains provincially maintained as unsigned Highway 7273. In Hamilton, Highway 6 now uses a new alignment from Highway 403 to south of the Hamilton Airport, connecting with the southerly leg to Caledonia and Port Dover. The new alignment opened as an undivided two-lane freeway in November 2004; it is expected to expand to a full 4-lane divided highway, and to extend to past
