Tolls were taken off the old Dallas - Fort Worth Turnpike, but I’m sure the original Dallas North Tollway has paid for itself many times over. They keep extending it. (What was intended to get the rich folks to work downtown now has frontage roads reaching half way to the Oklahoma line).
I remember vaguely the Dallas / Fort Worth Turnpike when we would go to Six Flags. I also remember when the Hardy Toll Road opened in 1988 when we moved to The Woodlands. Don’t tell me that road ain’t paid for after 30 years. It is just a tax on people who commute in from Montgomery County. We now have a toll road in Tyler of all places.
