So I have been over the Ohio river on I 65 and driven around Ok city where tolls are to be paid. They send me a bill I send them a check. In Illinois there is a small sign that I need to read and get information about paying the tolls. There use to be toll collectors but not any more that I can see. Does anyone have any experience with there? It looks like the toll jumps up a lot after 14 days if not paid.
