Opening each section will reveal the roads each agency supervises and payment options for the respective agency. they do have a way to search for unpaid tolls, but my ticket isn't showing up. The agency responsible for handling your toll payment will vary from road to road. I looked at the website for the Indiana toll road, they don't even have a phone number to call as far as I can see. Cars with the I-Zoom transponder - thats Indianas version of I-PASS - will. So maybe the machine thought a vehicle was stuck there and hadn't moved? When the Indiana Toll Road begins electronic tolling in June, fares will jump 72 percent for those who pay with cash. Has anyone else ever had this happen? The only thing I can think of, is that it read somebody elses transponder in a different lane, or somebody pulled up into my lane, and backed up before I got there. So I took off, but I still have my ticket. After a lengthy delay, the remaining toll plazas came online on Apin conjunction with increased cash toll rates. Wth? well I wasn't going to block a lane for 10 minutes, in the howling wind the today, and try to talk on their useless intercom to somebody 100 miles away through a McDonald's style drive thru speaker. i-Zoom is the electronic toll collection system currently used by the Indiana Toll Road (ITR), and is also usable on the ITRs adjacent sister road, the Chicago Skyway.On June 27, 2007, the system was implemented from mile 1 to mile 23 of the road. It's then that I noticed that the gate was open, green light was on, saying izoom or I pass whatever accepted, as if it had already been paid. I ran the whole toll road from Fremont to portage.my company doesn't have EZ Pass, but when I pulled up to the booth to pay with cash, the automated machine didn't even want to read my ticket.
