The Perimeter Highway is a four-lane highway that bypasses the city entirely—as it is located around the city (i.e. a ring road), mostly as an expressway with interchanges and at-grade intersections—allowing travellers on the Trans-Canada Highway to avoid the city and continue east or west. The Perimeter Highway was chosen over the freeways that would have been in the city. Now, the city has planned to create an Inner Perimeter Highway with Route 17, Route 90, Route 165, and Route 20.
