Join CDOT's Adopt a Highway Program!
Roadside litter costs millions of dollars annually to control. Often, it is impossible to keep up with the trash that people have dumped along the highway.
Join the thousands of volunteers who help keep Colorado beautiful by picking up litter along our highways. Participate in the Colorado Department of Transportation's Adopt a Highway Program!
Generally, the adopting group agrees to pick up litter from both sides of a highway for a two-mile section at a minimum of four times per year. However, each segment has its own special needs. A few segments may be longer or shorter than two miles or they may be in an area that doesn't need to be picked up more than twice in a year. Some groups have adopted several sections of highway.
The Colorado Department of Transportation (CDOT) maintains I-25. To report questions, comments, or concerns (such as garbage on the highway), contact CDOT directly.
