Toll roads are profitable. They are basically money-printers in fact. More/all of our expressways should be toll roads IMO. Then the people who use them will pay for them, and there will be money to keep them in good repair without needing appropriations from the general fund.
Small thing - I generally haven't seen tolled motorways called Freeways - but I haven't lived in the US in a long time. I'm familiar with turnpikes of course, and a tolled motorway in Orange County, CA.
