This is just a fun question.
If the gov't, I don't know who owns it, sold Interstate 90 in New York state to a private busniess how much would it have to be sold for?
The company could then toll or what ever they then want.
I would say at least a trillion dollars.
Selling all of I90 in the whole country could remove the US debt several times over with all the use it has.
How much would you want it to be sold for?
