Billboards

Currently, four states—Vermont, Alaska, Hawaii, and Maine—have prohibited billboards. Vermont’s law went into effect in 1968, Hawaii’s law went into effect in 1927, Maine’s law went into effect in 1977, and Alaska’s law went into effect upon its achievement of statehood in 1959. Rhode Island and Oregon have said no new billboards.
In Texas, 388 cities — including most large and medium-size cities — have ordinances prohibiting new billboards.
