Phoenix has a comprehensive roadway network of more than 4,850 miles of public streets. Phoenix’s roadway network is made up of arterial, collector, and local streets.
Arterials are major streets, which are typically the major north/south and east/west transportation corridors spaced at each mile.
Collectors are important transportation corridors generally running on the ½-mile north/south and east/west streets between the arterial streets.
Local streets are typically in residential areas, and provide connectivity between the collectors and arterials for local traffic.
