Cootes Drive, formerly known as the Dundas Diversion, is a city street in Hamilton, Ontario. The route connects York Boulevard and King Street in Dundas with Main Street (formerly Highway 2 and Highway 8) to the southeast, and is considered one of the first divided highways in Canada. Originally constructed as the Dundas Diversion, the route served to bypass several sharp turns along the nearby Highway 8, as well as to demonstrate the new dual highway concept that would soon thereafter evolve into the 400-series highway network. Construction began in 1936, and the route opened on the weekend of September 11, 1937.
