Earlier quoted context omitted.
As my dad told us every time we crossed a bridge when we were kids: "Tolls are a ratchet - they only move in one direction."
Because England is very old it has a whole bunch of things which did charge a toll and then that expired, so, nope. It does also have situations where people go "Hey, this toll bridge was built 50 years ago, surely the tolls should be abolished" and the people who built the bridge are like "Nope. See, here's the press about it 50 years ago saying what a great idea it is to have the tolls be slightly lower but perpetu…
That being said, the toll roads keep expanding so that they can continue to be operated by the private company that built them.
This is an arrangement the state government is quite happy with, because they do not have to budget for the maintenance of those roads and they are able to collect taxes on the revenue collected by the toll authority. Converting those toll roads would cause a spike in expenditures and a drop in tax revenue.
Therefore, there is a perverse incentive on both sides to keep the toll roads from being converted into public ones.
I have no idea if this sort of thing was prevalent in the past, especially in the UK. But I wanted to chime in about why several toll roads that were supposed to be paid off thirty years ago are still going strong. I suspect that 500+ years ago “build toll road, hand toll road to the public” was a lot more straightforward.
