The Florida Department of Transportation has cried foul over advertisements for other businesses the ball club places on its electronic billboard overlooking Interstate 275.
Under state law, signs that overlook a highway can advertise only stores and businesses at that location, unless specially permitted.
So the Rays, which has never had a permit for the sign, can use the 114-foot high billboard to advertise its ball games, events and concerts at the Trop. It can even advertise Chick-fil-A and other businesses with outlets at the stadium.
