which subsequently took over many development roads as provincial highways. Most of the northern sections of Highway 6 were included amongst these. Highway 68 was designated from Little Current north to Espanola on August 11, 1937. Two weeks later, on August 25, Highway 6 was designated in Bruce County, from Wiarton north to Tobermory. The section within Grey County was designated several months later on November 3. The lone remaining section of what would eventually become today's Highway 6, across Manitoulin Island, was not designated until December 7, 1955. The entirety of Highway 68 eventually became part of Highway 6 in the early to mid- 1980. Expressways and bypasses Longwoods Road extension Under the leadership of Thomas B. McQuesten, who would soon introduce the freeway to Ontario, a new grand entrance to Hamilton was planned. It would cross the Desjardins Canal and terminate at a traffic circle, with Highway 2 continuing east and Highway 6 north. This new road, known as the Longwoods Road Extension, was built partially as a depression-relief project in the early 1930s. Upon completion in 1932, Highway 2 and Highway 6 were routed off the Old Guelph Road onto the new route into Hamilton. This configuration remained until the construction of Highway 403 during the early 1960s, which was built over the Longwoods Road Extension. Mount Hope Bypass Due to the narrow spacing of buildings in the village of Mount Hope, a bypass of the village was built in the mid- to late 1950s. The original route is now known as Homestead Drive. The bypass opened on April 26, 1957, at which point the old routing was decommissioned. It was subsequently bypassed, when the new Highway 6 opened to the southwest of John C. Munro Hamilton International Airport, on November 26, 2004. Hanlon Expressway With the rapid suburban expansion of Guelph in the 1950s and 1960s, a revised transportation plan was conceived to handle the increasing traffic load. The Guelph Area Transportation Study was completed in 1967, and recommended a new controlled-access highway to allow through-traffic on Highway 6 to bypass the city. Route planning, engineering and design began on October 2, 1967 and was subsequently completed in 1969. Construction began between Waterloo Avenue and Stone Road in 1970; this section opened on June 28, 1972. The next section, from Stone Road to Clair Road, opened in October 1973.
