U.S. Transportation Secretary Sean Duffy confirmed that the federal government is planning a massive $22 billion redevelopment of Washington Dulles International Airport, marking one of the largest airport modernization projects in U.S. history. The ambitious proposal aims to completely transform the airport into a modern global travel hub by 2034.
Speaking at a conference in Washington, Duffy said the project would effectively create a “brand-new airport.” While financial details are still under discussion, the redevelopment is expected to include a major terminal expansion along with four new concourses designed to improve passenger capacity and travel efficiency.
The planned overhaul follows increasing criticism of Dulles International Airport’s aging infrastructure. Travelers and industry experts have long complained about outdated facilities, limited gate space, and the airport’s slow mobile lounges used to transport passengers across the tarmac. Federal transportation officials have also pointed to issues such as jet fuel odors inside concourses and the need for broader modernization.
President Donald Trump has repeatedly expressed support for rebuilding Dulles Airport, calling for upgrades that match the importance of the airport as the primary international gateway serving the Washington, D.C. region. Trump previously stated that while the airport’s iconic architecture is impressive, the overall passenger experience falls short of expectations.
Dulles Airport, located roughly 25 miles from Washington, D.C., is a major hub for United Airlines, which handles nearly 70% of airport traffic. In 2025, the airport recorded its busiest year ever, serving approximately 29 million passengers. A new 435,000-square-foot concourse with 14 gates is also scheduled to open later this year for United travelers.
Originally opened in 1962, Dulles was designed by renowned Finnish architect Eero Saarinen, whose distinctive terminal remains one of the airport’s most recognizable features. The Metropolitan Washington Airports Authority currently operates the airport under a congressional lease agreement.
