Adopt-a-Highway is a roadside clean-up program that promotes pride and local ownership in Washington. Become an Adopt-a-Highway Volunteer and you will be doing something great for your community. In addition, we will recognize your group's effort on a roadside sign. Thousands of miles of roadway statewide are available for adoption.
