Trump Unveils $22.5B Dulles Airport Overhaul, Ending 'Moon Buggies'
A sweeping capital plan would replace aging concourses at Washington Dulles International Airport, expand rail connections, and retire the facility's iconic mobile lounges after decades of service.
The White House has announced a $22.5 billion infrastructure initiative to comprehensively modernize Washington Dulles International Airport, according to a joint unveiling by President Donald Trump, Transportation Secretary Sean Duffy, the Metropolitan Washington Airports Authority, and United Airlines. The proposal targets approximately five million square feet of new or renovated facilities while preserving the airport's landmark Eero Saarinen-designed main terminal.
The capital program centers on replacing concourses C and D, which were erected more than four decades ago as interim structures but have remained in continuous operation since. Plans call for constructing a permanent midfield-concourse complex to serve as their replacement. The initiative also includes expanding the airport's AeroTrain network, installing a central pedestrian tunnel equipped with moving walkways, and developing a 32,000-space parking garage positioned closer to the main terminal building.
Among the most notable changes is the planned elimination of Dulles's distinctive mobile lounges—bus-like vehicles that transport passengers across the tarmac between the terminal and remote gates. Secretary Duffy described the vehicles as "absurd people's movers that everyone hates" in social media posts announcing the overhaul. The mobile lounges have been a signature feature of Dulles operations since the airport's opening, earning the nickname "moon buggies" for their unusual appearance.
Additional elements of the modernization blueprint include upgraded security checkpoints, renovated check-in facilities, enhanced baggage-handling infrastructure, and expanded commercial space for dining, retail, and hospitality. United Airlines passengers would see increased United Club facilities and a significantly enlarged United Polaris Lounge as part of the carrier's participation in the project.
The historic Saarinen terminal will be retained under the proposal, though conceptual designs suggest interior renovations and a 300-foot extension in each direction. The airport is already constructing Concourse E, a 435,000-square-foot facility slated to open later this year, which will integrate into the broader redevelopment timeline.
