Ado[pt a Highway

AdoptAHighwayThe Missouri Adopt-A-Highway program began in 1987. More than 4,700 groups and 47,000 volunteers in the program are focused on making Missouri’s roadsides cleaner and more attractive for our residents and visitors. More than 6,200 miles of roadway have been adopted.


Adopter groups include commercial and private enterprises, civic and non-profit organizations, families and individuals. MoDOT spends about $6 million annually to remove litter from more than 385,000 acres of right of way along 34,000 state highway miles.

Adopters perform about $1 million a year in litter cleanup and beautification efforts. Every area kept free of litter by adopters allows MoDOT to devote resources to other much-needed tasks.

Adopters have four options:

1. clean up litter

2. mow

3. beautify through landscaping

4. Grow Native! by planting native Missouri wildflowers and grasses

MoDOT provides adopters with a certificate of appreciation, a safety training video, safety materials, and a sign with the group’s name posted on each end of the adopted highway section. MoDOT provides trash bags and pick up and disposal of the bags of collected litter.


Litter Clean Up Adopters must:

            • adopt at least 1/2 mile of urban roadside or two miles of rural roadside
            • collect litter at least four times a year
            • sign a three-year agreement
            • submit an activity report to MoDOT
            • follow all safety procedures



No MOre Trash!

Since 2002, MoDOT has partnered with the Department of Conservation to establish No MOre Trash!, a litter-prevention campaign that encourages people to stop littering by educating them about the negative impacts of litter. Visit www.nomoretrash.org to find out more.
