The traditional gift for a 20th anniversary is china -- Missouri's Adopt-A-Highway program would settle for everyone putting their fast food containers in trashcans. This fall, Adopt-A-Highway in Missouri celebrates its 20th year anniversary, and while time does fly when you’re having fun, the Missouri Department of Transportation reminds Missourians there’s still plenty of work to do...and it’s time to do it. The program keeps Missouri roads beautiful and saves taxpayers money! To learn more about the program or to participate go to the Adopt-A-Highway page of MoDOT's web site.
