As originally reported on the Washington Post, the underground walkway that connects the Washington Dulles International Airport main terminal to the airports parking garage 1, will be temporarily closed due to construction of the Silver Line Metro station. During the time that the walkway is closed there will be no pedestrian access between the parking garage and the main terminal, but there will be shuttle buses in route to take passengers directly from the lots to their terminals.
“The expansion of the Silver Line Metrorail to Dulles International will play a significant role in the airport’s future,” said Jack Potter in a quote to the Washington Post, president and chief executive officer for the Metropolitan Washington Airports Authority, which manages Dulles and Reagan National airports. “This temporary tunnel closure ultimately will result in a much more accessible airport and an enhanced experience for passengers.”
The new $5.8 billion Silver Line station will be connected to the underground walkway between the garage and the main terminal and the construction is slated to last around 24 months. The first phase of the project opened in July 2014 with five stations, four in Tysons Corner and one in Reston. The second phase will not only include the Dulles Airport station, but five others in neighboring counties. It is expected that the Silver Line Metrorail will open in 2020.
