Really? PA had the first toll road...back in the late 1700's and it was privately owned. Indiana "sold" the Turnpike recently (actually, a 75 year lease), and did so with a Republican governor. The $4 billion brought in by the deal has already staved off one projected tax hike. The State also retains oversight on tolls.
It seems to me this guys has no clue what he's talking about. Check the FL arrangement and I'll bet you any amount of money that the State oversees the levying of tolls. Besides, if the company gets out of line with tolls, people will drive on the "free" highways. (Interesting: Something that costs $100,000/foot to build is called a freeway. My guess is that a liberal coined the term.)
Here is the complete bill. There seems to be a lot of things that need working out, but hey, the way my local DOT has boggled revenue spending, maybe a bonded private company would be forced to keep better track of revenue. We know how inept government 'crats are!
