Washington Dulles airport gains approval for $19.9 billion overhaul

The board overseeing Washington Dulles International Airport approved Wednesday a $19.9 billion overhaul plan, including $3.75 billion for new underground tunnels to replace slow vehicles that move passengers across the tarmac. The Metropolitan Washington Airports Authority said the $6.2 billion reconstruction of the main terminal is set to start in late 2027. The authority expects the tunnels, an automated passenger transportation system, and a new concourse to be finished by 2034, along with main terminal renovations. Airline boarding costs are projected to rise to $60–$65 by around 2038 from $13 today, to help cover $1.1 billion of those tunnel and transit costs. The plan follows a larger $22 billion proposal announced last month by President Donald Trump.
