President Donald Trump unveiled a $22.5 billion plan yesterday to modernize Washington Dulles International Airport, aiming to transform one of the nation’s busiest airports with faster transportation, expanded terminals, and a redesigned passenger experience.
Trump announced the project from the Oval Office alongside Transportation Secretary Sean Duffy and United CEO Scott Kirby, after being personally involved in shaping the plans. United handles about 70% of passenger traffic at Dulles.
The redevelopment will preserve Dulles’ iconic sloped-roof main terminal, designed by architect Eero Saarinen, while giving the interior a modern makeover with an open foyer and upgraded airline check-in kiosks.
The project also includes four new concourses, a larger terminal, and parking facilities closer to the main entrance. A new 14-gate concourse for United Airlines passengers is already scheduled to open this fall.
A major highlight of the project is the retirement of Dulles’ mobile lounges, which have carried passengers since the airport opened in 1962. They will be replaced by an expanded underground Aerotrain system and additional moving walkways to speed up travel between terminals.
How the project will be funded
Congress has not appropriated funding for the massive overhaul.
Duffy said the financing would include bond issuance, with support from airlines, and that United would help cover the costs.
The Metropolitan Washington Airports Authority will oversee the project, which will be carried out while keeping existing runways in service and minimizing major flight disruptions.
Despite complaints about outdated facilities, Dulles recorded its busiest year in 2025, serving 29 million passengers, a 6.4% increase from the previous year.
