Plans for a major expansion at Washington Dulles International Airport have been submitted to the Federal Aviation Administration (FAA) for review. The expansion includes new offices, retail space, and a fifth runway, which was approved by the airport board on July 16.
Washington Dulles serves as the primary international hub for the United States capital. The idea of a fifth runway dates back to the airport's planning in the 1950s and was part of the 1985 master plan. The last runway addition was completed in 2008, with both the fourth and fifth runways receiving approval simultaneously.
Currently, Washington-Dulles has four runways: three north-south and one east-west. The proposed fifth runway will be designated Runway 12R/30L and will be constructed parallel to US Route 50. This new runway aims to improve capacity during adverse weather conditions when only one east-west runway is operational.
