There are no toll booths(they don't accept cash payments), there are plenty of signs, I have seen them. The tolls are are on both the Kennedy (South bound I-65) and Lincoln (north bound I-65) bridges. Crossing was free for about two months, up until the end of Dec. last year, then the tolls took effect. The tolls, the rates, the start date were all blasted on radio, TV, internet, newspapers and every other type of media for months, before the tolls started. There are no tolls on the Clark Memorial Bridge or Sherman Minton Bridge. If you want to avoid the tolls you can use one of them to get to Indiana. By the way, the tolls are the same at the east end bridge, too. I don't live near the Ohio River or even in Jefferson Co. and have no interest or intention of going to Indiana, but I know all of this about the tolls on the bridges, because I could not avoid all of the information that was put out for months before the tolls began. I could not avoid them.
