Virginia State Route 267  State Route 267 (SR 267) is a primary state highway in the US state of Virginia. It consists of two end-to-end toll roads – the Dulles Toll Road and Dulles Greenway – as well as the Dulles Access Road, which lies in the median of Dulles Toll Road and then extends east to Falls Church. The combined roadway provides a toll road for commuting and a free road for access to Washington Dulles International Airport. The three sections are operated and maintained by separate agencies: Dulles Toll Road and Dulles Access Road are maintained by the Metropolitan Washington Airports Authority (MWAA); the Dulles Greenway is owned by TRIP II, a limited partnership, but is maintained by Atlas Arteria, an Australian company which owns the majority stake in the partnership. The Dulles Access Road's median hosts the Silver Line of the Washington Metro for much of the length between Reston and Falls Church. The Dulles Access Road is a four-lane, highway that runs "inside" the Dulles Toll Road along its median. There are no general-access exits from the westbound lanes, and no general-access entrances to the eastbound lanes, with the exception of gated slip ramps to and from the toll road that buses and emergency vehicles can use. The Access Road was built from the Beltway as part of the construction of Dulles Airport, and opened with the airport in 1962. It was extended to I-66 in 1985. Until 2006, the Dulles Access Road was operated by the Virginia Department of Transportation (VDOT) under contract with the Metropolitan Washington Airports Authority, the owner of the land under both the Access Road and the Dulles Toll Road, and has the unsigned designation of State Route 90004. The Dulles Airport Access Road can be used only for travel to and from Dulles Airport and other businesses (such as air freight, hotels, and gas stations) on the airport grounds. Although it is illegal to use the Access Road without conducting such "airport business", some commuters evade the toll and the traffic on the Toll Road by taking the Access Road to the airport, then "backtracking" to their exit. For a couple of years prior to the opening of the Dulles Toll Road, VDOT issued special stickers allowing commuters (for a fee) to backtrack legally along the access highway, but these were discontinued when the toll road opened. Since the opening of the Dulles Toll Road, the only major modification to the Access Road has been the construction of the Silver Line inside the median, and the construction of a flyover exit ramp from the eastbound Access Road to State Route 7.
