The notion that it had to be built in the same spot because “towns have grown up around it” is nonsense. The population of Nyack, the largest town “around it” is only 12% larger than it was when the road was first built. The real issue is that building the highway at the outlet of the “Tappan Zee (Sea)” would mean impossibly long environmental studies... decades... that would probably end up costing as many billions as were wasted rebuilding the bridge where it stands.
This is great information and a good point. I’m impressed.
