Tolls are calculated after selecting an entry and exit point from drop-down menus or by clicking directly on the map, says the Metropolitan Washington Airports Authority, which operates the toll road.
Depending on the entry and exit points, one-way rates for two-axle vehicles range from $1.00 to $3.50. Tolls are the same whether paid by cash or E-ZPass.
The resulting route is highlighted on the map and the total toll for the trip is displayed. Tolls displayed are for the Dulles Toll Road only, and do not include other adjacent toll highways.
“This new online feature makes access to toll information more convenient for the traveling public,” Cyndi Ward, Dulles Toll Road manager, said in a release. “The toll calculator is an intuitive planning tool that elevates customer service by giving travelers a predictable experience before they drive on the Dulles Toll Road.”
