About Ontario Highway 420 in brief

Summary Ontario Highway 420King’s Highway 420 is a 400-series highway in the Canadian province of Ontario. It connects the Queen Elizabeth Way with downtown Niagara Falls. The highway has a speed limit of 80 kilometres per hour, making it the only 400- series highway to have a speedlimit less than 100 kilometres for its entirety. East of Stanley Avenue the route is signed as Niagara Regional Road 420 and known as Falls Avenue. It is also the location for the annual Cannabis Conference and Protest, usually taking place around April 20. The route was originally constructed as a divided four-lane road with two roundabouts. It formed part of the QEW between 1941 and 1972 initially as the southeastern terminus. It was assigned a unique route number during the reconstruction of the four- lane divided highway into a freeway and the construction of the large interchange at the freeway’s western endus. In 1998, the section of Highway 420 east of Stanley Avenue was transferred to the responsibility of the Regional Municipality of Niagara and redesignated as Regional Road  420. This portion was designated a part of Highway until 2000, when the Ministry of Transportation of Ontario still assists with the maintenance of it under a Connecting Link agreement.

It provides access to the Rainbow Bridge crossing into the United States as well as the tourist district of the city of Niagara Falls, where it is also called Falls Avenue and Newman Hill on approach to the bridge. The road was named Newman Hill until March 2012, when it was named Falls Avenue until it descends a hill over the Niagara Gorge. The name Falls Avenue is a reference to the number 420 in cannabis culture, which has been used as a symbol for the legalization of the drug in Canada and the U.S. since the 1970s. The freeway ends at an at-grade intersection with Montrose Road. It continues east as a limited-access expressway named Niagara Regional Road 420 to connect with the Rainbow Bridge international crossing between Canada and the United States over Niagara River; this was part of Hwy 420 until 1998. At 3.3 km, it is the shortest 400-Series highway, travelling through Niagara Falls from Montrose Road to Stanley Avenue, on the outskirts of the city’s tourist district. At the bottom of the hill, the route curves to the southwest, where the route provides access to the southwest where the Rainbow Bridge crosses the Niagara River.
