Washington Metropolitan Area Transit Authority
Rosslyn Station is at the center of new development, which features the tallest buildings in the DC area. The new all-elevator entrance is the focus of Rosslyn’s central plaza, which is defined by a residential and office tower. Restaurants and active storefronts, as well as the entrances to the towers, will surround this new public space.
The Metro entrance consists of three high-speed elevators extending from the plaza to the new mezzanine approximately 110 feet below grade. The mezzanine space is carved out of rock, creating a natural vault lined with precast concrete panels. The interior finish is similar to the precast in the Red Line stations north of Dupont Circle with inset acoustic panels as well as indirect lighting integrated with the horizontal ribs. A new passage connects to the existing escalator passageway and is protected by large fire doors. These doors close in an emergency allowing the mezzanine to act as an area of refuge. A new emergency stair tower flanks the elevators connecting to the street level through an emergency hatch. Below the mezzanine new service rooms supply fresh air and air-conditioning to the mezzanine.
At the surface a glass enclosure surrounds the three elevators and vent shafts. Although separated by glass the elevators and vents appear as one translucent structure, with vision glass surrounding the elevator cabs for safety. The vent on the south side of the elevators is enclosed with blue stone in a pattern similar to the design of the plaza. The entire enclosure is up-lit with LED fixtures embedded in the base surrounding the structure. A glass canopy protects patrons from the weather while waiting.
The new entrance has been an instant success and easily moves patrons in and out of the Metro station.
