Trying to figure out the toll cost on our trip from Indiana to Niagara Falls. We are talking I-90 and I trying to find what to plan for with toll costs. I found on one website that my rig is considered a "medium" truck due to pulling the pup. Is that right? Where can I find the individual toll cost? Can I pay with a debt card? Do I need exact cash? Sorry with the questions? Just needing some direction. We leave Saturday morning!!!
