The Ohio Turnpike existed prior to, or was constructed prior to the interstate designation. The problem there is that the bonds have long been paid off, but the stated decided (and was allowed) that it could continue to charge the toll in perpetuity. Which violated its own initial documents, its own purpose.
I will say, though, that the Ohio Turnpike is one of the better kept roads in that state, which is a LOT more than be said for the extremely costly Pennsylvania turnpike.
Chicago tolls - ridiculous.
About 18 years ago, when I lived in Northeast Ohio, I drove up to Great Lakes to see my nephew graduate Navy boot camp. It costed some 25-30 bucks to pass through Chicago. Granted, I didn’t know all the roads so I could have avoided some of that gouging. But it was absolutely ridiculous that I spent as much on tolls in Chicago as I did on fuel for the trip.
Roads that collect tolls should firstly, be required to ONLY collect tolls necessary to maintain and upgrade that specific road, and second, they lose ALL federal funding for that road and it becomes solely the responsibility of the state. But must still be maintained to interstate standards. But in NO circumstances can the tolls collected on any specific road be used for any other purpose.
same in illinois. they got around things by refinancing old into new, therefore, the bonds would never be paid off...
