The board overseeing Washington Dulles Airport has approved a comprehensive $19.9 billion renovation plan, which includes a substantial $3.75 billion investment to construct new underground tunnels and replace the existing slow-moving vehicles that currently transport passengers across the tarmac.
The main terminal's $6.2 billion reconstruction is scheduled to commence in late 2027, with the new tunnels expected to begin construction in early 2029 and be completed by 2034. This overhaul is crucial for improving the airport's operational efficiency and passenger experience, potentially positioning Dulles as a more attractive hub for international travel
