Modernizing the adopt-a-highway program to improve its ability to meet its original purpose within existing fiscal limitations.

SB 5556 modernizes Washington's adopt-a-highway program, affecting volunteer groups, businesses, and sponsors who participate in roadside clean-up and maintenance. The bill explicitly links the program's operation and recognition efforts to specific legislative appropriations, emphasizing fiscal limitations. It expands adoptable locations to include rest areas and park-and-ride lots, and clarifies that activities can include planting pollinator-friendly vegetation and graffiti removal. Additionally, it requires the Department of Transportation to submit annual reports on program participants and prohibits politically active organizations from participating.
