Highway Beautification Act (1965)
President Lyndon Johnson signed the Highway Beautification Act in 1965, restricting billboards along interstate highways. States that failed to regulate outdoor advertising lost 10% of their federal highway funds.
The law pushed states to adopt billboard control programs, including permit systems and limits on off-premise signs.
It established the federal role in local billboard regulation and the permit-based framework cities use to manage off-premise signage.
The Las Vegas review operates within this permit-based framework: a 1994 special use permit is being reconsidered under city land use rules that trace back to this regulatory tradition.
