A newly released animation offers a glimpse into the planned $22 billion transformation of Washington Dulles International Airport. The ambitious redevelopment project aims to modernise terminals, expand passenger capacity, and enhance travel infrastructure at one of America's busiest aviation hubs.

President Donald Trump and Transportation Secretary Sean Duffy are expected to announce plans Wednesday for a $22.5 billion overhaul of Dulles International Airport.

The renovation at the airport will include four new concourses, an underground aerotrain, and moving sidewalks.
