  • Arterial Streets: The most heavily used streets in the street system. Major arterials are usually four or more lanes, serve as major access routes to regional destinations, and carry an average of more than 20,000 vehicles per day. Paso Robles has approximately 31 miles of arterials, including Spring Street, Creston Road, Niblick, and Vine Street.
  • Collector Streets: Streets that carry less traffic than arterials and provide access to neighborhoods and commercial and industrial areas. Major collectors typically carry between 2,500 and 7,000 vehicles, and neighborhood collectors typically carry between 1,500 and 2,500 vehicles per day. Paso Robles has approximately 11 miles of major collectors, including Rambouillet and Scott Street.
  • Local Street: Streets whose primary function is to provide access to individual properties. Typically, they carry fewer than 1,500 vehicles per day. Paso Robles has approximately 118 miles of local or "neighborhood" streets, and 5 miles of alleys.

Other System Terms

  • Improved Street: Streets constructed in accordance with the specifications established by the Paso Robles Community City Engineer. Improved streets generally include engineered road beds and surfaces, storm drainage systems, sidewalks, street lighting and street trees.
  • Travel Lane: The portion of the street in which vehicles operate. Typically, travel lanes are about 10 to 12 feet wide. The paved surface of the travel lane is called the driving course or top lift.
