Adopt-A-Highway Common Questions

Litter must be picked up a minimum of four times per year. Most urban locations require litter pickup once or twice per month.

MoDOT does. We also supply safety vests, caution flags, safety video, safety brochures, and safety tips for working along roadsides.

MoDOT requires a detailed plan outlining the areas where planting is to be done including the types of plants. MoDOT personnel will review the plan to determine if it will enhance the roadside appearance while not creating a safety hazard.

Adopters sign a three year commitment to the program. However, the agreement can be terminated at any time. Each location is reviewed periodically to ensure both parties are fulfilling their agreement.

The Missouri Department of Transportation has established rules and regulations for the program to ensure safety and consistency in its operation. All adopters are expected to know and abide by these standards.

 All it costs you is your time. MoDOT provides the signs, safety materials, trash bags and disposal.
