Districts (Highway Maintenance)

Maintenance of a highway extends from the right of way fence on one side of the road to the other side. This work includes:

  • Surface maintenance, such as filling potholes and sealing cracks;
  • Shoulder maintenance, such as repair and blading;
  • Roadside maintenance, such as guardrail and fence repair;
  • Drainage maintenance, such as clearing drains and ditches; and
  • Removing obstructions, debris, snow, and ice.

Some functions, such as highway striping, lighting, and traffic signals, are conducted on a regional basis.

ADOT's maintenance districts are broken down into seven geographical areas:
