RIDOT Clean Rhodes Program RIDOT has three programs open to all Rhode Islanders that will keep litter off our roadways. We have tried to do it all by ourselves, but we can’t even though we spend $800,000 a year on garbage pickup. With our programs, you can adopt your own piece of road, and make it beautiful for everyone. The Rhode Island Department of Transportation offers three programs to combat litter: Adopt-A-Road Adopt-A-Spot Adopt-A-Highway With these programs, businesses, organizations or individuals can adopt an area to keep litter free. RIDOT has provided an interactive map on their website so people can see what spots, roads, highways are available to adopt.
