Washington Dulles Airport Set for $22.5 Billion Renovation to Replace Concourses and Mobile Lounges

WASHINGTON — Washington Dulles International Airport is set to undergo a massive $22.5 billion multiyear overhaul designed to replace aging facilities, expand passenger capacity, and phase out the airport’s iconic mobile lounges.

Unveiled Wednesday during an Oval Office presentation by President Donald Trump and Transportation Secretary Sean Duffy, the modernization initiative represents a substantial increase from a previously allocated $7 billion plan. Developed in coordination with the Metropolitan Washington Airports Authority and United Airlines, the project will construct or renovate more than 5 million square feet across the airfield complex located approximately 25 miles west of downtown Washington, D.C.

“This transformation is another step in our ongoing efforts to make Washington, D.C., safe and beautiful again,” Trump said.

Funding for the $22.5 billion capital program will rely on municipal bonds alongside financial contributions from United Airlines and other participating carriers, federal officials confirmed. In U.S. aviation infrastructure, municipal airport revenue bonds are traditionally repaid through landing fees, terminal facility leases, and passenger facility charges rather than federal income tax revenues.

“So it’s going to be bonded for $22.5 billion,” Duffy said during the announcement. “United is going to partake in part of the payment. But the airlines who participate in the project are going to pay for it.”

The structural core of the overhaul centers on tearing down Concourses C and D—facilities originally erected in 1985 as temporary structures meant to last roughly 10 to 15 years, yet kept in service for four decades as Dulles grew into a major transatlantic hub. In their place, modern facilities will be built with expanded gate capacity and updated luggage handling networks.

A major operational focus of the project is the permanent retirement of the airport’s legacy mobile lounges. Introduced when the original Eero Saarinen-designed terminal opened in 1962, the elevated shuttle vehicles transport passengers across taxiways directly to planes or midfield terminals.

“We are going to get rid of the people movers,” Duffy said. “These are like elevated busses… And they’re slow, and people are angry about them.”

To replace the vehicle system, the new design expands the airport’s underground AeroTrain network, adds a central walkway connecting concourses, and establishes a dedicated pedestrian passage leading international arrivals to a new U.S. Customs facility.

As the primary hub operator at Dulles, United Airlines will expand its footprint inside the redesigned terminals. The project includes additional United Club space and one of the largest United Polaris Lounges in the airline’s global network, along with consolidated security screening checkpoints and expanded parking structures.

Federal officials selected the blueprint after evaluating more than 30 competitive proposals submitted to the U.S. Department of Transportation following a December 2025 request for ideas.

Construction will be executed in phases to maintain continuous flight operations. Pending environmental and regional permitting reviews, site preparation could begin as early as next spring.

Near-term terminal expansion is already underway, with the first phase of Concourse E expected to open later this year, adding 14 United gates, direct AeroTrain access, and upgraded passenger lounges.
