Botched MDX Open-Road Toll System About to Produce Big Bills for Some Users

By now, drivers whizzing through Miami-Dade Expressway Authority open-road toll plazas without SunPass transponders were supposed to be paying monthly invoices sent to the addresses where their vehicle license plates are registered.
