The Adopt-A-Highway program on Oahu will reopen on Wednesday, July 1, 2020. Thank you so much for your patience during our COVID-19 closure. To ensure your continued health and safety, Supply Pickups are now contactless at our Waimalu Field Office. Please contact our Adopt-A-Highway Coordinator at for more information or if you have any questions.

When conducting cleanups, please adhere to the most recent guidelines from the State and the CDC.

One of the most critical ways to keep our storm water run off free of pollutants and debris is to adopt a highway. The State DOT Adopt-A-Highway program is a public service program that allows volunteers from any organization to pick up litter along Hawaii’s state highways. This is your chance to make a personal contribution to a cleaner Hawaii! The DOT can help your community group, church or businesses adopt a highway and provides all safety materials, trash bags, schedule trash pick-ups and 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.

To find out the most up-to-date information on adopting a state highway, contact Adopt-A-Highway at

About the Adopt-A-Highway Program

Why You Should Help

Litter destroys the natural beauty of Hawaii’s highways.
Litter is unsightly. It destroys the natural beauty of Hawaii’s highways.
Debris physically harms marine life via ingestion or entanglement.
Litter affects our ocean environment both directly and indirectly. Direct impacts occur when marine life is physically harmed by marine debris through ingestion or entanglement. Indirect impacts occur when the clean up of the marine debris results in ecological changes.
Beautiful highways show visitors that we care about our environment
Clean highways help lead to beautiful beaches that welcome visitors and show that we care about our community and our environment.

Adopt-A-Highway: The Safe Way


Adopt-A-Highway program safety tips
Volunteers must:

  • Be in good physical condition, including good eyesight and hearing.
  • Be mentally alert.
  • Be responsible for their own safety and the safety of their crew.
  • Be at least 12 years old. Groups under 18 must have two adults per ten volunteers present at all times.
For your safety, carpool to the Adopt-A-Highway cleanup site.
For Your Safety:

  • Knives, machetes, axes and similar objects should not be carried by crew members.
  • Don’t attempt to compact trash sacks to make room for more. Injuries from broken or jagged objects often result from this practice. Fill the sack with what goes in easily, then get another bag.
  • Park all vehicles well clear of the road way and at least ten feet from the shoulder’s surface.
  • Keep vehicles on the same side of the highway as the volunteers.
  • Work one side of the highway at a time.
  • Carpool to the clean up site to reduce the number of vehicles on the road.

Protect Yourself and Others:

  • Conduct a refresher session on safety awareness each time a crew goes out.
  • Whenever possible, face oncoming traffic while you work. Be prepared to move out of the way of vehicles in an emergency.
  • Don’t work in bad weather.
  • Work during daylight hours only.
  • Avoid overexertion. Drink plenty of water.
  • Do not cross traveled sections of roadway.
  • Avoid using headsets: they could interfere with your ability to hear oncoming traffic or warnings.
For your safety, wear your Adopt-A-Highway t-shirts or safety vests, covered shoes and gloves.
What You Should Wear

  • Your Adopt-A-Highway t-shirts or safety vests.
  • Covered shoes (no slippers!)
  • Gloves (strongly recommended)
  • A hat, sunglasses and sunscreen
