King`s Highway 403, also known as Highway 403 or Highway four-oh-three is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. Highway 403 is also known as the Chedoke Expressway within Hamilton. Although the Highway 403 designation was first applied in 1963 to a short stub of freeway branching off of the QEW, the entire route was not completed until August 15, 1997, when the Brantford to Ancaster section was opened to traffic.
