Are all traffic signals in Florida eventually going to be replaced?|195519

I live in Tampa and most of the traffic signals here hang from wires. I know it_s petty, but I can_t stand it, it_s just so ugly! In other parts of the state they_ve been putting the new black ones up on poles, so does anyone know if they_re going to be doing that state wide or is it only in certain communities? And why the hell did they start hanging them from wires in the first place?

Here in Orlando they usually just have it at busy intersections and nice streets. Its probably their goal to make it all like that but the wire thing is cheaper and does the job but I think they are ugly also.
