During this voting many discussions ensued i.e. 4 lanes U.S. 1 in the Keys and the criteria which must be established to go to reverse lanes during a storm. Manpower, money resources etc. With this in mind a roll call was done. Most of the storms have come in towards coast and end up north. You would be heading up the coast in these three counties and 95 is too close to the ocean to be used as a one-way route.
Most people go to the Turnpike to get to the center of the state.
Most people go Turnpike or I-75. Don't think there is a need these counties. Dade, Broward, Palm Beach do not think it would be feasible to consider I-95 for one way. No Two exits off 95 and they would have to use Route 60 and Route 60 is NOT recommended as a feasible evacuation route for anyone. Would be the only route to use if you were going to send people to the Turnpike if you one way the Turnpike.
