The document summarizes a study by the Metropolitan Washington Airports Authority (MWAA) investigating the feasibility of developing air rights over the Dulles Toll Road. The MWAA study found that building a platform over the Reston Town Center station would cost $1.469 billion but have transportation challenges. A follow-up study by Fairfax County concluded additional development from air rights would worsen traffic and not be aligned with the comprehensive plan. While air rights have development potential, significant hurdles around costs, transportation impacts, and land leasing would need to be addressed. A feasibility study for Fairfax County was estimated to cost $150,000-$200,000.
