Roadway Class


Functional Classification (Federal)

The Federal Highway Administration road designation scheme for rural, small urban, and urbanized areas defines the role that any particular road or street should play in servicing the flow of trips through a highway network. Standards for highway classification were developed during 1969-1971 using criteria and procedures specified in the 1968 National Highway Functional Classification Study Manual. The scheme may be expressed as:

‘Rural’ Classifications

  • 1 = Rural Interstate
  • 2 = Rural Principle Arterial
  • 6 = Rural Minor Arterial
  • 7 = Rural Major Collector
  • 8 = Rural Minor Collector
  • 9 = Rural Local Access
‘Urban’ Classifications

  • 11 = Urban Interstate
  • 12 = Urban Other Freeway or Expressway
  • 14 = Urban Other Principal Arterial
  • 16 = Urban Minor Arterial
  • 17 = Urban Collector
  • 19 = Urban Local Access


Town Highway Classification (State)

The Vermont State classification of roadways is based on the level of traffic and percent of the state-aid apportionment for town highways. For example, apportionment a town’s Class II roads is determined by the town’s percentage of all Class II town highway mileage in the entire state (see: VSA Title 17, Chapter 3, Section 306 Appropriation).

The scheme may be expressed as:

  • Class I = (6% of state annual highway appropriation). Class I town highways form the extension of a state highway route system and carry a state highway route number. They are maintained by the municipality, but they do have a State-aid apportionment. The agency shall determine which highways are to be Class I highways
  • Class II = (54% of state annual highway appropriation). Class II town highways generally provide access to neighboring municipalities or connect residential and/or commercial activity centers and would have at least 500 AADT. The municipality maintains the road, but has the option to notify VTrans to replace the yellow centerline pavement marking if it is paved. According to VSA Title 19, Chapter 3, Class II town highways are those town highways selected as the most important highways in each town. As far as practicable they shall be selected with the purposes of securing trunk lines of improved highways from town to town and to places which by their nature have more than normal amount of traffic. The selectmen, with the approval of the agency (of Transportation), shall determine which highways are to be Class II highways.
  • Class III = (50% of state annual highway appropriation). Class III Town Highways include all of the other town highways that are negotiable in all seasons. They are fully maintained by the municipality, but do have a State-aid apportionment to help municipalities fund their maintenance.
  • Class IV = (0% of state annual highway appropriation). Class IV Town Highways are fully maintained by the municipality and have no State-aid apportioned for their maintenance. Local selectpersons determine which highways are Class IV town highways.
  • State Highway = State highways are those highways maintained exclusively by the Agency of Transportation.
