Adopt-A-Highway

Adopt-A-Highway (AAH) is an MDOT program designed to help keep the state's highway roadsides clean and attractive. Participants adopt both sides of a section of state highway roadside to clean up for at least a two-year period. A minimum two-mile stretch of roadway is recommended. All types of state highways may be adopted, including two-lane roads, limited access highways, boulevards and business routes.

Since 1990, AAH local groups have collected over a million bags of trash. Currently 2,900 groups are participating in the program and have adopted over 6,000 miles of Michigan highways.

Safety information

Participants are required to conduct a safety meeting before each pickup and wear an MDOT-provided safety vest while working along the roadside.

Michigan Sponsor A Highway Program

The Michigan Sponsor A Highway Program lets businesses sponsor professional litter removal on designated state highways. Sponsors are recognized with FHWA-approved signs displaying their name and logo.

By participating, companies support cleaner highways and contribute to their communities, allowing MDOT to use litter removal funds for road improvements instead.
