We’re going to make it maybe the best,” Trump told journalists, saying it is “another step in our ongoing efforts to make Washington, DC safe and beautiful again.” US transportation secretary Sean Duffy, speaking alongside Trump, said the project would cost US$22.5 billion, with United Airlines – for which the airport is a major hub – footing part of the bill. Dulles – located some 25 miles (40km) from Washington – is the area’s main international airport, with more than 29 million travellers passing through it in 2025, the most on record.
