Calgary
Roads and highways

Calgary lies at the crossroads of Highway 2 and the Trans-Canada Highway, making it an important hub for the transit of goods across Canada and along the CANAMEX Corridor. Stoney Trail encircles the city, completing a full ring road. The last segment in west Calgary was completed in December 2023, and is now open to the public. Freeways and expressways are mostly called "trails". Highway 2, named Deerfoot Trail, is the main north–south route through Calgary and one of the busiest highways in Canada. Much of Calgary's street network is on a grid where roads are numbered with avenues running east–west and streets running north–south. Until 1904 the streets were named; after that date, all streets were given numbers radiating outwards from the city centre. Roads in predominantly residential areas, as well as freeways and expressways, do not generally conform to the grid and are usually not numbered. However, it is a developer and city convention in Calgary that non-numbered streets within a new community have the same name prefix as the community itself.
