Has it ever been considered to keep the old Big Carlos Bridge and repair it to be used but not open? Boats could use the Matanzas Bridge route to get to the Gulf.
Another bridge could be built next to it and each could be one-way traffic. In case of an evacuation it would be beneficial to use both for one-way off the islands.
I’m sure the destruction cost is horrendous plus 20% override.
