Toll charges must be paid or disputed within eighty days of using the toll facility. Pay By Mail bills will be mailed to the registered owner of the vehicle if no account holder address is available. If there are toll charges not paid by the due date of the bill, the subsequent bill will be assessed a reprocessing fee at a rate set by the commission. If a reprocessing fee is assessed, this fee must also be paid within eighty days of using the toll facility. Toll charges can be paid online, by mail, in person or by phone.
