The airport is accessible via the Dulles Access Highway
The Dulles Access Highway is a convenient way to get to and from Dulles International Airport. The airport is situated about 26 miles outside Washington, D.C., in the Northern Virginia suburbs. The Dulles Access Highway is a four-lane, 13.65-mile (21.97 km) highway that runs between the westbound and eastbound roadways of the Dulles Toll Road, along the latter's median. It was built as part of the construction of Dulles Airport and opened in 1962, later extended to I-66 in 1985.
The Dulles Toll Road operates four vehicle lanes eastbound and four lanes westbound, with one High Occupancy Vehicle (HOV) lane in each direction. During rush hour, the left lane is restricted to HOVs, and vehicles with two or more people may switch their E-ZPass Flex into HOV mode to avoid tolls. The Dulles Access Highway is free of charge for traffic heading to or from the airport, but it is restricted to airport use only. All vehicles on the Access Highway must be going to or coming from the airport on airport business, and commuters using the highway to evade the toll on the Dulles Toll Road may be subject to ticketing and fines.
The Dulles Toll Road is an eight-lane, 16.15-mile (25.99 km) toll road that runs outside the Dulles Access Road. The toll road begins just inside the Capital Beltway near West Falls Church and travels westward through Fairfax County, terminating at the entrance to the Dulles Greenway, a privately-owned toll road that is a continuation of Route 267. The Dulles Access Highway can be accessed from the left lane of the Toll Road at select locations, and signage will direct drivers to the appropriate exits.
The combined roadways of the Dulles Toll Road and Dulles Access Road provide a convenient and efficient means of travelling to and from Dulles International Airport, with the latter offering a toll-free option for those conducting airport business.

The main terminal was designed by architect Eero Saarinen
Washington Dulles International Airport, commonly known as Dulles Airport, is located in the US state of Virginia, specifically in Chantilly, about 26 miles (42 km) west of downtown Washington, D.C. The airport is named after John Foster Dulles, who served as US Secretary of State under President Eisenhower. With its unique design and architectural significance, the main terminal building has become an iconic feature of the airport.
The main terminal was designed by the renowned Finnish-American architect, Eero Saarinen. Saarinen was known for his innovative and futuristic designs, and the Dulles main terminal is considered one of his most iconic works. Construction of the terminal began in the 1950s, and it officially opened in 1962. The design was revolutionary at the time, with its sweeping curves and bold use of concrete, steel, and glass. Saarinen's vision was to create a structure that embodied the spirit of flight and the jet age, and the main terminal's distinctive shape certainly achieves that.
The main terminal building is characterized by its curved roof, which resembles the shape of a flying bird or an aircraft's wings. This theme of flight is further emphasized by the large mobile sculptures designed by Alexander Calder, titled "Mobile" and "Stabile," which hang from the ceiling, representing aerial acrobatics. The use of glass and steel creates a sense of openness and allows natural light to flood the space, while the exposed concrete adds a sense of strength and solidity.
Saarinen's design also incorporated a unique approach to the flow of passengers. He envisioned a efficient and seamless journey for travelers, with separate levels for arrivals and departures, and an underground people-mover system, known as the AeroTrain, which transports passengers between the main terminal and the concourse where the aircraft gates are located. This system was designed to accommodate the increasing number of passengers and the growing demand for air travel.
The main terminal at Dulles International Airport stands as a testament to Eero Saarinen's innovative and forward-thinking architecture. Its unique design has become a landmark and a gateway to the nation's capital, welcoming millions of travelers each year. The terminal's blend of form and function continues to inspire and influence architects and designers to this day.
