The State Department of Transportation, Highways Division, Oahu District (HDOT Highways), is kicking off a multi-year study this month, one that should give its engineers and scientists more information about the man-made trash and debris found along our highways. The study, which focuses on state routes on the island of Oahu, will help HDOT Highways determine how to reduce the proliferation of trash on highways in the future, thereby lessening the amount that finds its way into the storm drain system.

These traps will capture the debris that comes off highways from sources such as unsecured loads that are being transported, trash thrown away by pedestrians, and items blown in from nearby areas. By better understanding the composition of this trash, HDOT Highways will be able to devise a more strategic approach to reduce this trash load in the future.

The first trash trap has been set up near the Halawa interchange.
