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 two years. 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. For more information, visit Michigan Department of Transportation Adopt-A-Highway website.
