They are public works, often in states that simply can’t afford to build or maintain their own infrastructure. But the point remains.
I’m not saying there is any wrong with the service, but I think it’s a worthwhile indicator of what life will be like as wealth inequality continues to accelerate.
Perhaps other parts of the world have privately operated roads, but I’m not aware of them.
So, the ones in states that can't afford to build or maintain them are often private roads or PPP.
Since you live in the area, and are talking about toll roads, I assume you also probably know of the name Cintra, who are Spainiards. And Cintra is, in fact, a private toll road operator who has owned roads around Austin previously
I mentioned Texas 130, which was operated by Cintra, but was still technically operating under TxDOT: https://en.wikipedia.org/wiki/Texas_State_Highway_130
Agree that it's a more accurate metaphor than just "toll roads".
My understanding is that Cintra exited the Austin TX toll road business around a decade ago after profits from SH 130 failed to materialize
