Temporary Closure of Pedestrian Tunnel to Parking Garage 1 beginning Jan. 11

January 5, 2016

The underground tunnel connecting Parking Garage 1 and the Main Terminal will be closed to accomodate the construction of Silver Line station at the airport. Increased shuttle bus service will be provided for passengers.

Beginning Monday January 11, at 7 a.m., the northern portion of the underground pedestrian walkway between Parking Garage 1 and the Main Terminal at Washington Dulles International Airport will be closed to facilitate Metrorail Silver Line construction of the future Dulles Airport Station. Signage within the garage and the terminal will direct passengers to increased shuttle bus service for travelers parking in the garage.

  • Transportation between Garage 1 and the Main Terminal will be provided by shuttle buses approximately every five minutes during peak hours.
  • Buses will pick up and drop off passengers at three locations on the south (terminal-facing) side of Garage 1.
  • The parking shuttle buses stops at the Main Terminal at two locations along the second arrivals curb, near the exit at Door #2 and exit at Door #6.
  • While the walkway to Garage 1 is closed, there will be no pedestrian access between Garage 1 and the Main Terminal.
  • Pedestrian access between the Terminal Parking Lot and the Main Terminal via the walkway will be maintained. The walkway from Garage 2 to the Main Terminal will be unaffected and remain open.

“The expansion of the Silver Line Metrorail to Dulles International will play a significant role in the airport’s future,” said Jack Potter, president and chief executive officer for MWAA. “This temporary tunnel closure ultimately will result in a much more accessible airport and an enhanced experience for passengers.”

The Metrorail station will connect to the existing underground walkway between the garage and the terminal. The work on the station connector, which is expected to last up to 24 months, includes multiple utility and communication line installations and reconfigurations, shortening the existing moving walkways to accommodate the new rail station, and adjusting the walkway grade to match the station's mezzanine level.

The Dulles Corridor Metrorail Project is being built in two phases. Phase 1 runs from East Falls Church through Tysons Corner to Wiehle Avenue in Reston and opened for passengers July 26, 2014. Phase 2, currently under construction, will begin at the Wiehle-Reston East Station and travel through Herndon to Dulles Airport ending at Route 772 in Ashburn. The project is being built by the Metropolitan Washington Airports Authority. The design build contactor for Phase 2 is Capital Rail Constructors. When Phase 2 is completed, it will be transferred to the Washington Metropolitan Area Transit Authority to operate.
