Ontario Highway 417
King's Highway 417, commonly referred to as Highway 417 and as the Queensway through Ottawa, is a 400-series highway in the Canadian province of Ontario. It connects Ottawa with Montreal via A-40, and is the backbone of the highway system in the National Capital Region. Within Ottawa, it forms part of the Queensway west from Highway 7 to Ottawa Road 174. Highway 417 extends from the Quebec border, near Hawkesbury, to Arnprior, where it continues westward as Highway 17. Aside from the urban section through Ottawa, Highway 417 passes through farmland that dominates much of the fertile Ottawa Valley.

Within Ottawa, the Queensway was built as part of a grand plan for the city between 1957 and 1966, and later reconstructed to its present form throughout the 1980s. The eastern section, from Gloucester to the Quebec border, opened in 1975 in preparation for the 1976 Montreal Olympics. Sections west of Ottawa have been under construction since the mid-1970s, with the section bypassing Arnprior opening on November 29, 2012 and another 5.3 km stretch in December 2016.
