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

Sponsor-A-Highway Program

The Michigan Sponsor-A-Highway Program provides civic-minded businesses the opportunity to sponsor professional litter removal services on designated state highways. In return, sponsors are recognized with Federal Highway Administration approved full-color signs featuring their company name and logo.

Participating in the Michigan Sponsor-A-Highway Program gives companies the opportunity to be recognized for their contributions to the local community and the environment. The program also provides for cleaner highways and allows MDOT to use funds allocated for litter removal to improve Michigan's roads.
