Drivers who use the Dulles Toll Road are learning how much deeper they'll be digging to drive on the highway.
The Metropolitan Washington Airports Authority has revealed its projected toll increases for the coming years.
The proposed toll for a driver using the main plaza and one on- or off-ramp would be $2.75 next year, $3.50 the following year and $4.50 in 2015.
The money will be used to fund Metro's Silver Line construction.
