I went ahead and looked, and the people who did this are dead wrong about Florida, and there are not three Ohio turnpikes! The three "turnpikes" are various sections of the road between different geographical points according to your own source.
And, as far as I can tell from my American Map Corporation atlas, there is one friggin' Maine turnpike with one named spur (and a couple unnamed short ones)! And I'll wager my road atlas is far more accurate than your source.
I've gotten into this discussion before, and toll roads are especially useful to a state when the primary traffic on a road is from out of state.
This is true, for instance, with Indiana and Ohio, where the toll road in each state simply allows traffic from New York to go to Chicago. In Ohio, around 85% of drivers on the toll road are from out of state. I suspect it's about the same for Indiana.
These out of state drivers don't contribute any taxes to Ohio (other than the occasional fill-up while they are driving through) but yet toll road exists almost solely for their use.
Indiana has really gotten a sweet deal since it recently leased its toll road to a corporation for around $4 billion in cash. That $4 billion is being used to fund all sort of construction projects around the state, including major upgrades to the existing interstates and an extension of I-69, none of which would be possible without this money--which, again, comes from out of state drivers.
Since July, the interest earned from the lease of the Toll Road has made $82 million for Hoosiers. Indiana earns over $6 a second in interest.
Tell me why I should be opposed to the use of these toll roads?
