A fast, smooth ride for D.C.-area riders

Tens of thousands of people in the Washington, D.C., region are now traveling on the newest rail line built by a Bechtel-led team. The Metrorail Silver Line, running 11.5 miles (18.5 kilometers) through an extremely congested corridor, brings rail service to the fast-growing areas of Northern Virginia and will provide a direct ride from Dulles International Airport to downtown Washington, D.C.

Inside the Project

Phase 1 of the Dulles Corridor Metrorail extension

  • Ranks as one of the largest construction projects in the United States
  • Marks the first use in the United States of technology codeveloped by Bechtel that enabled secure, two-way communication and data exchange between surveyors and satellite office staff and GPS-guided construction machinery, which greatly enhanced construction productivity and quality

The Dulles Corridor Metrorail  is among the world's most sophisticated rail systems and boasts the latest safety features, such as advanced control systems. Passengers can expect one of the smoothest train rides ever experienced as a result of innovative design and construction.

This is a project built in partnership with the community. We employed more than 2,000 people, most of them from the Washington, D.C., area, and contracted with more than 200 local businesses over the course of the project. —Larry Melton, Bechtel's executive director for the project.

Dulles Metrorail project goes online

Phase 1 includes five stations, 6 miles (nearly 10 kilometers) of elevated track, and twin tunnels running beneath one of the busiest office and retail centers in the United States—where 700,000 cars travel each day.

Construction required three enormous overhead cranes custom-built to lift segments of elevated guideway into place between huge piers. One of the 366-ton behemoths—heavier than a fully loaded Airbus A350—stretched across 12 lanes of traffic over the Capital Beltway. A total of 3 miles (nearly 3 kilometers) of the Phase 1 alignment is of aerial track, including both the inbound and outbound guideway.

State-of-the art technologies combined with each metro station’s architecture, natural light, and carefully selected finishes enhance  the passenger experience. All stations include pedestrian bridges in addition to escalators and elevators.
