Functional classification is the "process by which streets and highways are grouped into classes, or systems, according to the character of service they are intended to provide." In basic terms, a road can be functionally classified as:

  • Arterial: These roads provide mobility so traffic can move from one place to another quickly and safely.
  • Collector: These roads link arterials and local roads and perform some duties of each.
  • Local: These roads provide access to homes, businesses, and other property.

The Alaska Department of Transportation and Public Facilities (DOT&PF) is responsible for designing, constructing, and maintaining many of these roads to ensure safe and efficient travel. To fulfill that responsibility, ADOT&PF must review and update the functional classification of all public roads, including those in your community.
