Frequently Asked Questions
Is there a free way to get to Dulles Airport?
Yes, the Dulles Airport Access Highway (in the toll road median) is FREE for airport-bound traffic. Access it from left-lane exits on the westbound Dulles Toll Road. The Silver Line Metro also provides toll-free access to the airport.
Do HOV vehicles get toll discounts?
No, ALL vehicles pay the same tolls regardless of occupancy. HOV-2+ vehicles can use the left lane during rush hours for faster travel, but still pay full toll rates.
Why did toll rates increase so much?
Toll increases fund the $6 billion Silver Line Metro project. Toll road users pay nearly half the cost, with $0.50 of each toll specifically for Silver Line bonds. Increases are scheduled every 5 years through 2048.
Can I still pay cash on Dulles Toll Road?
No, cash payments ended in March 2023 when the road converted to all-electronic tolling. You must use E-ZPass or Pay-by-Plate (license plate billing with additional fees).
Are hybrid vehicles exempt from HOV restrictions?
No, hybrid vehicles lost HOV exemption in September 2019 due to federal law changes. Only Clean Special Fuel vehicles with proper license plates and motorcycles remain exempt from HOV occupancy requirements.
When will toll increases end?
Current schedule calls for increases through 2048, but they could end in 2033 if MWAA successfully pays off Silver Line bonds early. Strategic debt refinancing has already reduced projected increases.
