We are a good location, but as you state, there is no way they can afford to get the real estate needed to make it affordable.
About the only solution I could see is running an elevated rail above medians on I-95, I-91, I-84, I-384, rt9, rt2, rt 15, etc. But talk about expensive infrastructure.
you need a new, straight (as an arrow) ROW through Harrison NY, Greenwich, New Caanan, Darien, etc.
As if.
