The Metro extension responded to the imperative to link Dulles International Airport with downtown Washington and address the increasing transportation needs of the local communities. The 13 new stations function as state-of-the-art transportation centers and catalyze continued growth in an area where the nation's worst traffic congestion threatens economic vitality and quality of life. Station designs integrate the solid architectural tradition of the original Metro system with a lighter, friendlier appearance. Steel panels, glazing, and translucent sound barriers create openness and transparency while protecting system patrons from outside elements. KGP studied all the station's alternative locations for a variety of station types. Each station platform, mezzanine, and all functional service spaces were laid out establishing a basic footprint and cost for the overall system. Presentations were made to local stakeholders and the public.
