I'm from Oklahoma, and their toll roads suck. The indian turnpikes are everywhere. At least the speed limit is 75 there! I have a Pikepass. They also tried to tell us when the roads were built that when construction was paid for there would be no more tolls, but now they say that included maintenance so there will always be a toll.
Minimum of $1.00 and most are between $1.50-$5.00. It's crazy how much they charge. And the most expensive ones are on the shortest roads with the fewest exits!!
