Now here is a sight for sore eyes. Yes, this one is scary as well, but not remotely as these before it. This seven-mile-long structure is actually the second one of this kind. There was one more, but it was decommissioned because it wasn’t made in a way that would allow boats to pass by. The scare factor on this one grows when you try to use it during Florida’s hurricane season.
