Who pays the tolls, the tooth fairy?
Paying for roads at toll booths is a bad way to fund roads. The public pays for them one way or another, and handing a virtual monopoy for travel between city A and city B to a private company is a bad idea.
Private toll roads were the norm in Colonial America. We got rid of them for a reason.
The only people who pay for a toll road are those who CHOSE to use it and pay the price. You can always chose to use the pre-existing free roads, that may be longer or slower or more crowded, but they are free. So anyone who doesn't want to pay the toll doesn't pay for the road. And your claim of a 'virtual monopoly for travel between city A and B' is nonsense. Did you even bother to read the article? I-35 will remain free, and there are several other free route options in that corridor. How do you travel from A to B right now, because those routes will still exist and won't be tolled. Only the new routes will be tolled, or new mainlanes that don't exist right now. But if you want to legally drive at 85mph, you'll have to pay a toll.
Hardly oppressive to have choices.
