Board overseeing Washington Dulles airport to vote on $19.9 billion overhaul plan

The Dulles project is the latest massive reconstruction project in the Washington area Trump is pushing for. Dulles is about 25 miles (40 km) from the U.S. capital and opened in 1962.

Finnish architect Eero Saarinen designed the airport's terminal building, a distinctive structure with a sloping roof that sweeps up toward the sky on opposite sides.

The board that oversees Washington Dulles airport will vote on Wednesday on a $19.9 billion overhaul plan that includes $3.75 billion to build new underground tunnels and replace slow vehicles that transport passengers across the tarmac.

The $6.2 billion reconstruction of the main terminal at the primary international airport serving the Washington region is set to begin in late 2027, the Metropolitan Washington Airports Authority said in a summary of the tentative plan posted Monday. It said that building new tunnels would begin in early 2029, to get rid of the "People Mover" vehicles and extend to a new concourse.

Construction on one new planned concourse would not be completed until at least 2039. Of the total, $4.4 billion was previously approved.

President Donald Trump announced the $22 billion plan last month. The $19.9 billion proposal to be voted on does not include a massive new parking garage and transportation center.
