Airlines and destinations Passenger carriers Cargo carriers Statistics Top destinations Airline market share Annual traffic Ground transportation Roads Washington Dulles is accessible via the Dulles Access Road/Dulles Greenway (State Route 267) and State Route 28. The Dulles Airport Access Highway is a toll-free, limited access highway owned by the Metropolitan Washington Airports Authority (MWAA) to facilitate car access to Washington Dulles from the Capital Beltway and Interstate 66. After it opened, non-airport traffic between Washington and Reston became so heavy that a parallel set of toll lanes were added on the same right-of-way to accommodate non-airport traffic (Dulles Toll Road). However, the airport-only lanes are both less congested as well as toll-free. As of November 1, 2008, MWAA assumed responsibility from the Virginia Department of Transportation both for operating the Dulles Toll Road and for the construction of a rapid transit rail line down its median. Route 28, which runs north–south along the eastern edge of the airport, has been upgraded to a limited access highway, with the interchanges financed through a property tax surcharge on nearby business properties. The Dulles Toll Road has been extended to the west to Leesburg as the Dulles Greenway. Public transportation Washington Metro service is available to Dulles via a station on the Silver Line. Service began operation on November 15, 2022. Fairfax Connector bus routes 981 and 983 serve Washington Dulles, connecting to the Herndon–Monroe park & ride lot in Herndon, the Reston Town Center transit in Reston, the Wiehle–Reston East Metro station, and the Steven F. Udvar-Hazy Center Air and Space Museum. Formerly, the Metrobus 5A route served at the airport. Megabus provides service from Dulles to Charlottesville and Blacksburg. Washington Flyer has a monopoly to operate cabs from Washington Dulles Airport. Uber and Lyft are popular modes of transport to and from the airport and MWAA receives a $4 fee per trip, which is included in the quoted fare. Accidents and incidents On January 21, 1970, the first commercial flight of the Boeing 747 was delayed, when an engine malfunction caused the aircraft in question to be temporarily grounded. Another
