Trash and debris can become pollution in our ocean. To help make sure roadway trash out of our streams and the ocean, the HDOT encourages groups to join our Adopt-A-Highway program which is a public service program that allows volunteers from any organization to pick up litter along Hawaii’s state highways. The DOT can help your community group, church, or business adopt a highway and will provide all safety materials and trash bags, will schedule trash pick-ups, and will even erect a highway sign to recognize your group’s cleaning efforts.

Adopt-A-Highway groups agree to:

  • Adopt a two-mile portion of state highway for a minimum of two years.
  • Pick up litter on that highway at least four times a year.
  • Provide safety training for their volunteers before each cleanup.
