The city is served by two freeway corridors. The primary corridor is east-west and consists of provincial Highway 417 (designated as the Queensway) and Ottawa-Carleton Regional Road 174 (formerly Provincial Highway 17); a north-south corridor, Highway 416 (designated as Veterans' Memorial Highway), connects Ottawa to the rest of the 400-Series Highway network in Ontario at the 401. Highway 417 is also the Ottawa portion of the Trans-Canada Highway.
