Why would they still want to make toll roads? I makes no sense aside from someone wanting to profit from essential public needs. You'd think if a bunch of people designate a small group to do government stuff on their behalf to make life better they do those sensible things centrally.
Responsive tolling on roads makes a lot of sense. Roads carry more people at 50 mph than they do at 30mph. So if you use the price of the road to keep the road moving, you can make a more effective road, rather than letting it be overwhelmed and less useful.
I thought an article just a few days ago proved that money-based restrictions or incentives only work if people are not left with any other choice and generally makes everyone sad and angry. Perhaps it's a culture or locale issue; we don't really have toll roads here.
All joking aside, if its not a toll road is not getting built in Austin. I'd love to Dig & Cap I-35 all the way to airport blvd.
