Highway Beautification Act (1965)
President Lyndon Johnson signed the Highway Beautification Act, which required states to control billboards along interstate and federal-aid highways or lose federal highway funds. The law capped outdoor advertising near those roads and mandated removal of nonconforming signs with just compensation.
States adopted billboard-control programs to keep their highway funding, and a federal-state inspection regime took shape.
The 1965 act established the enduring public framework for regulating billboards, one that local variance reviews now operate within.
The 1988 Las Vegas variance is part of this same regulatory tradition: local boards decide whether each sign may stand.
