“Indiana sold the Tollroad to some Spaniards.”
...and what happened to the toll rates, and how does that compare with the cost of actually operating the roads?
Hint - much of the tolls now are to pay off the debt that Cintra has from purchasing (technically, leasing) the road in the first place. It has NOTHING TO DO with the cost of operating the road. Instead, Mitch Daniels got himself a nice $6 BILLION slush fund (i.e., the money from selling the road) to hand out to his friends. Nice deal for him, but not for people that live in and drive through Northern Indiana.
I believe that one is still able to use studded tires though.
