The Metropolitan Washington Airports Authority (MWAA) board, which oversees Washington Dulles International Airport, is set to vote on Wednesday on a $19.9 billion renovation plan. The proposal, described as one of the largest airport overhauls ever considered, aims to modernize Dulles while preserving its historic main terminal.

Key elements of the plan

The renovation would add new concourses, a renovated main terminal, an underground AeroTrain system and additional moving sidewalks to replace the airport’s aging mobile lounge vehicles. Reconstruction of the main terminal is scheduled to begin in late 2027 if the board approves the package.

The plan does not call for a new parking garage, transportation center or hotel. A separate project, Terminal E, is already under construction and funded with $4.4 billion from the Biden administration.

Funding

The $19.9 billion cost would be covered primarily through MWAA bonds paid by the airlines, accounting for $15.5 billion. Passenger facility charges would contribute about $1.1 billion, while the remainder would be financed through other revenue streams.

The full buildout is expected to take roughly 15 years, with phased construction to minimize disruption to travelers.

Background

Officials note that the Trump administration accelerated the planning process earlier this summer, helping move the project forward more quickly than originally anticipated.

Stakeholders will watch the board’s decision closely, as the renovation could reshape the region’s air travel infrastructure for decades to come.
