# MWAA Seeks Firms for Dulles Aerotrain Expansion

The Metropolitan Washington Airports Authority (MWAA) is seeking firms for a reported **$3.75 billion** expansion of the Aerotrain at Dulles International Airport in Virginia. The project is intended eventually to replace the airport’s mobile lounges. The available information does not specify a formal solicitation, requirements, procurement milestones, or a contact, so the opportunity is not yet detailed enough to assess bid schedules or qualification criteria.

- The reported scale and airport-transit focus make this relevant to firms with experience in major transportation infrastructure, airport systems, and related construction or engineering work.
- Interested firms can prepare by assessing their relevant capabilities and monitoring MWAA announcements for the formal opportunity and solicitation details.
- No deadline, award date, or contract number is provided; companies should not assume a procurement schedule or that an award has been made.
