Hi! One of the most convenient ways to pay for toll roads, bridges, and tunnels is to use the ipass illinois system. To do this, the driver needs to purchase a transponder, install it on the windshield of his car, and the payment will be made automatically, the main thing is to make sure that there is enough money on the account. But if it happens that money will not be debited from your account, you should contact customer service and report it in order to avoid problems with non-payment of toll roads.
