The e470 is a private road, however, if you go around a toll(very easy with a bike) the state patrol will give you a ticket for toll evasion. How wild is that? What if you put a toll up at your driveway entrance and someone went around? Could you call the state patrol to give them a ticket?
Anyway, it's odd. I did scope out all the toll booths. At night, on a bike it would be trivial to go around with no issues.
