Dirt (unpaved/gravel) roads

The USA Standard (matrix table) does not specify how to set unpaved road segments, so we define that here. Unpaved roads may or may not be classified in the states' functional classification system. If they are, set the road type according to the functional classification. If they are not, set the road type to Dirt Road / 4x4 Trail.

To stay aligned with the USA Standard, an AR County Road functionally classified as Local, or a Local street classified as a Collector, is still to be set as a Primary Street. A Local street functionally classified by the DOT as Local, is a Street. Otherwise, dirt is dirt. The majority of dirt roads in Arkansas are not functionally classified.

If the users' Waze client options are set to avoid dirt roads, they will still be routed on dirt roads functionally classified as either a Collector or Street. This is necessary to insure beginning-to-end routing should the origin/destination be on an unpaved road however, Waze route pruning will only consider these lower-priority roads (Primary Street, Street, Dirt) near the origin/destination.

Examples:

  • An unpaved County Road identified in the AHTD FC system as a Collector is a Primary Street.
  • An unpaved street identified in the AHTD FC system as a Local road is a Street.
  • Any unpaved road not listed in the AHTD FC system is Dirt.
