Adopt a Highway


Roadside litter costs millions of dollars annually to control. Often, it is impossible to keep up with the trash that thoughtless people have dumped on us. We need your help! Join the thousands of volunteers who help keep Colorado beautiful by picking up litter along our highways

Bookcliffs HwyWhat’s required?

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 2 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.

Adopting groups are encouraged to sort litter when picking up, taking recyclable materials to recycling centers. The group may keep any money collected from their recycling efforts.

What does the Colorado Dept of Transportation (CDOT) provide?

  • CDOT will provide a sign crediting the group for volunteering on adopted section of highway.
  • CDOT will also provide litter bags, safety vests, a Safety Video and a Meth Lab Waste Recognition Video and other information to your group.
  • CDOT will haul the litter bags away after the group places the full bags at the edge of the roadway.

Sponsor a Highway

Colorado DOT’s Clean Colorado sponsorship program compliments our Adopt a Highway program and offers one more way for community and civic organizations, businesses, non-profit organizations and private citizens to participate in the effort to keep the roadsides and rest areas of Colorado attractive and clean from litter.

We partner with Adopt a Highway Maintenance Corporation to administer the program. They provide all marketing, sign installation and litter removal services at no cost to the state by obtaining sponsorships to fund these operations.  Sponsored areas are recognized with an acknowledgement sign displaying the sponsor’s name, logo or both.  Acknowledgement signs are not intended to be an advertising medium or any kind of forum for public speech or political opinion.    

All highways and interstates under Colorado DOT’s jurisdiction are included in the Clean Colorado program.  The cost to participate in the program varies by highway and frequency of cleaning.  Highway and Interstate sections are sponsored in one mile segments and are cleaned either 12 or 26 times a year.  Available ramps, rest areas and chain-up stations are cleaned at least 12 times a year.

Since the inception of the Clean Colorado program in 2005, participation continues to grow with businesses and organization that have civic pride and are committed to giving back to the community.  Best of all, this program cost the traveling public nothing. No State funds are expended to generate these great litter removal services and the program allows our department to better utilize maintenance time and funds to be directed to more substantial safety related activities.
