The Highway Beautification Act was enacted in 1965 to improve the appearance of highways in the United States. It aimed to control outdoor advertising, such as billboards, and to promote the planting of trees and shrubs along roadways. The act sought to enhance the scenic beauty of highways while ensuring safety for drivers. The legislation was championed by Lady Bird Johnson, the wife of President Lyndon B. Johnson, who advocated for environmental conservation and beautification efforts. The act provided federal funding to states that implemented programs to reduce visual clutter and improve roadside landscapes, contributing to a more pleasant driving experience.
