The Friendship Heights station uses the four-coffer arch design found at most underground stations on the western side of the Red Line, but it is the only Metro station with this design that has mezzanines at both ends of the platform. The station's walls are more rounded than counterparts such as Van Ness-UDC and Tenleytown-AU. It is one of 11 Metro stations constructed with rock tunneling and is accordingly deeper than most other stations. Its platform is more than below its north entrance. The escalator has a length of and rises feet above the mezzanine level. The escalator ride from the common room at the north entrance to the mezzanine level takes roughly a minute and a half. The station has entrances to both its northern and southern ends. The southern end is served by a bank of four high-speed elevators that connect the south mezzanine to a street-level exit at Wisconsin Avenue and Jenifer Street NW, which was built in 1985. At the northern end, five street entrances come together in an upper mezzanine, leading to a set of three escalators to the platform. Three of these entrances are on the Maryland side of Western Avenue, including an elevator, and two are on the District side. The station's main entrance surfaces in a bus depot underneath the Chevy Chase Metro Building. Another comes from a side entrance to the lobby of an entrance to the former C-level of
Mazza Gallerie. Another goes to Chevy Chase Pavilion. The northern elevator is at street level. The newest entrance, located off Wisconsin Avenue next to
The Shops at Wisconsin Place, opened between 2011 and 2022, replacing an earlier entrance that led into a
Hecht's. == References ==
