The ICC saw traffic of more than 30,000 vehicles daily when it opened for test drives, but that number dropped when tolls were introduced March 7. Officials said the current traffic volume is about 10,000 vehicles per day. Ridership has grown at about 5 percent a week since the initial drop-off, they said.

Drivers who don’t have an EZPass receive a bill in the mail based on the address for their car’s registration. The state adds a $3 service fee to the cost of each bill mailed to help recover processing costs.

Most states charge usage fees for EZPasses, too. But one writer suggests that travelers purchase a transponder from the Peace Bridge Authority, which adminsters a Niagara river crossing and doesn’t charge usage fees. Dr. Gridlock gives a run-down of other options.
