About the Dulles Airport Station

What is the Dulles Corridor Metrorail Project?

It is a 23-mile extension of the existing Metrorail system, which will be operated by the Washington Metropolitan Area Transit Authority (WMATA). The line runs from East Falls Church to Washington Dulles International Airport west to Ashburn. The new line breaks off from WMATA’s Orange Line near the I-66 and follows the Dulles Connector Road west to the Dulles Toll Road, using the median of the connector road and the Dulles Airport Access Highway and the Dulles toll road/Dulles airport road .The project is being built in two phases, the first of which opened in July 2014.

Is this the same thing as the Silver Line?

Yes. However, while under construction the project is referred to as the Dulles Corridor Metrorail Project. Once the segment becomes operational with the existing metro system, it will be officially named the Silver Line.

What is the current status of Phase 1?

Construction of Phase 1 began in March of 2009, following many months of preliminary work preparing roadways and relocating utilities in Tysons Corner area.  The Metropolitan Airports Authority (MWAA) completed construction in 2014 and transferred the line to the Washington Metropolitan Area Transit Authority who opened the line on July 26, 2014.

How many stations are there and where are they located?

The project consists of 11 new stations, five stations in Phase 1 and six stations in Phase 2.

Phase 1 station locations

  • McLean Station:  Route 123 and Scotts Crossing
  • Tysons Corner Station: Route 123 at Tysons Boulevard
  • Greensboro Station: Median of Route 7, west of Route 123 and east of Westpark/Gosnell Drive
  • Wiehle-Reston East: Median of the Dulles Toll Road at Wiehle Avenue

Phase 2 stations

  • Reston Town Center : Median of the Dulles Toll Road, west of Reston Parkway
  • Herndon: Median of the Dulles Toll Road near the existing Herndon Monroe Park and Ride
  • Innovation Center: Median of the Dulles Toll Road near Route 28 and the Center for Innovation Technology
  • Dulles Airport Station: Along the face of Parking Garage 1, opposite the terminal
  • Route 606: Median of the Dulles Greeway at Route 606
  • Route 772: Ashburn  in the median  of the Dulles Greenway near Route 772 (Ashburn/Brambleton)

Where is the commuter parking at the stations now open?

The only commuter parking in Phase 1 is at the Wiehle-Reston East station. There is a temporary privately-owned lot at the McLean Station.

Is there public parking at all stations?

The following stations will have public parking:

  • Herndon
  • Innovation Center
  • Route 606
  • Route 772

Dulles Airport will continue to operate existing parking garages, and there will be no additional parking created at the Reston Town Center Station as part of the project.

Who built or is building it?

The Metropolitan Washington Airports Authority (MWAA) is responsible for the construction of the Dulles Corridor Metrorail Project.

Who is the Phase 1 contractor?

The Phase 1 contractor was Dulles Transit Partners, a team led by Bechtel Infrastructure.

Who is the Phase 2 contractor?

Capital Rail Constructors, a joint venture of Clark Construction Group, LLC, and Kiewit Infrastructure South Co., is leading the design-build effort for Phase 2.

Package B, also known as the Rail Yard contract, was awarded to Hensel Phelps.

Who is the operator?

The Washington Metropolitan Area Transit Authority (WMATA) will operate the Silver Line once construction is complete.

How is the project funded?

(2) Does not include $150 million from the Commonwealth that is being used to pay interest on Dulles Toll Road revenue bonds.

(3) Grant from Northern Virginia Transportation Authority (NVTA) can only be used to pay or reimburse capital costs for Innovation Center Metrorail Station.

(4) Congestion Mitigation Air Quality Grant (CMAQ) can only be used to pay or reimburse capital costs for Innovation Center Metrorail Station.

With Phase 1 open, why do I continue to see construction on the rail line and nearby streets in Tysons and Reston?

Punch list items continue to be completed on the project. These are items that don’t hinder the operation of the Silver Line, including paving and landscaping.

Are the station locations for Phase 2 final?

Yes, the station locations were determined during development of the Final Environmental Impact Statement which was complete in 2004.

Will Phase 2 open at once, or when each station is complete?

As occurred in Phase 1 of the Silver Line, the entirety of Phase 2 will open for revenue service at the same time.

What is traction power substation? How many will be built?

A Traction Power Substation (TPSS) is a facility that converts electric power from the form provided by the electrical company for public utility use to the voltage, current type, and frequency, required for operating the Silver Line.  Nine TPSS will be built, each approximately one mile from the other down the Phase 2 alignment. 

In addition, six smaller Tie-Breaker Stations (TBS) will be constructed.  Tie-Breaker Stations allow Metro to break the rail line into sections that can be powered down for maintenance without affecting the power supply to the rest of the system.

Who is building the parking garages?

Fairfax and Loudoun counties will be financing and constructing the new parking facilities. Fairfax County is responsible for the garages at Herndon and Innovation Center Station, while Loudoun County is responsible for the garages at the Route 606 and Route 772 stations.

About the Dulles Airport Station and tracks

Where is the station located?

The station will be located on Saarinen Circle directly in front of Daily Garage 1 facing toward the Main Terminal.

How will passengers get from the station to the main terminal?

Escalators from the Dulles Airport Station will tie into the existing underground tunnel that currently services Daily Garage 1. The tunnel is equipped with moving walkways which decrease time (and steps!) spent moving between the station and the terminal.

Is there commuter parking at this station?

There will be no commuter parking at this station; however, existing parking garages for airport travelers will remain. 

During construction how will terminal users get from the public parking deck where the station is being built to the terminal? Will the existing tunnel for pedestrians in this area be closed?

The pedestrian tunnel that connects Daily 1 Parking Garage and the Dulles Main Terminal will be closed for approximately 12 months during the construction of the Dulles Station in order to also connect the station to the tunnel.  Parking Garage patrons and other pedestrians will be still be able to pick up an Airport Shuttle Bus at any of the three stops currently located on the north side of the garage for a quick trip to the terminal.  The project will announce the closure of the pedestrian tunnel well in advance of the start of work at that location. 

Will a new rail yard be built to accommodate the Dulles Corridor Metrorail Project?

Yes, a new rail yard will be built on Dulles Airport property and will contain five major buildings (service and inspection, maintenance-of-way, train wash, transportation/police, and warehouse). The rail yard will also be capable of storing 168 cars, making it the largest in the WMATA system.  This project is currently in design phases.
