Trump Proposes 32,000-Car Dulles Garage as Airport Plan Exceeds Parking Demand Forecasts

Summary
32,000 spaces would make the proposed Dulles garage the world’s largest and add roughly 10,000 spots beyond the airport’s current 22,000-plus capacity.
MWAA’s July 2025 master plan said existing parking would be sufficient until at least 2045, even as the authority was already planning a far smaller 6,400-space, three-story deck for 2031-2034.
Parking experts said a garage about 2.5 times larger than the biggest U.S. terminal garages would create major throughput, wayfinding, ventilation and fire-safety challenges, especially during construction at an operating airport.
A 32,000-space structure could cost more than $900 million at Washington-area above-ground rates and, if built mostly above ground, could rise to about 15 stories—higher than Dulles’s 65-foot Saarinen terminal.
The proposal is part of Trump’s $22.5 billion Dulles overhaul, but it has also drawn criticism because the airport gained a $6 billion Metro connection in 2022.
Can a $22 billion Dulles remake preserve Saarinen’s iconic terminal while fixing passenger frustration, financing risks, and years of construction disruption?
Why does Trump’s preferred Dulles plan rely on United and tax-free bonds—and what could that mean for travelers, rivals, and the airport’s future?
Will Dulles’s massive redesign finally end the mobile-lounge era, or just speed up an airport overhaul already years in motion?
