On Feb. 28, the toll along the eastbound stretch of I-66 hit $47.50.
The tolls are paid by drivers who choose to ride alone and are based on a dynamic pricing system, which changes the rate every six minutes, based on speed and traffic volumes.
Many drivers — and some politicians — have complained about the fluctuating and high toll rates. The toll runs along 10 miles of I-66 inside the Beltway in Northern Virginia. Carpool and public transportation vehicles don’t pay the toll.
