Oahu Adopt-A-Highway Program Coordinator

Keeping trash off our highways is one of the most critical ways to ensure our storm drains are free of pollutants and debris. HDOT Highways Adopt-A-Highway program is a public service program that allows participants from any organization to pick up litter along Hawaii’s state highways.

Embrace your chance to make a personal contribution towards a cleaner Hawaii!

HDOT Highways can help your community group, church, school, or business with the opportunity to adopt a section of Oahu’s state roads, provide all safety materials, trash bags, and will schedule trash pick-ups for your highway location. HDOT Highways will even erect highway signs 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.

As of March 5, 2021, HDOT has resumed the Adopt-A-Highway program. Adopt-A-Highway groups that would like to conduct clean-ups must comply with all State of Hawaii COVID-19 rules.
