Since 1987, Missouri's Adopt-A-Highway program has involved volunteers across the state working together to clean up Missouri. Currently, more than 5,300 groups and 50,000 volunteers in the program are focused on making Missouri’s roadsides cleaner and more attractive for our residents and visitors. More than 6,400 miles of roadway have been adopted.
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.
