History
The station was opened on July 1, 1977, along with 16 other stations as part of the opening of the – segment. On April 17, 2016, the Metroway bus rapid transit system was extended to Pentagon City, with the station becoming the northern terminus. In February 2021, the Arlington County Board awarded a $6.5 million construction contract to add a second surface elevator to the station, with expected completion in spring 2023.Station layout
Pentagon City station has two underground side platforms serving two tracks. The station has four entrances from the mezzanine level, which runs under Hayes Street: entrances from the east and west sides of Hayes Street via escalator, a direct entrance from the Fashion Centre at Pentagon City, and an entrance from the northeast corner of the 12th and Hayes Street intersection. The pedestrian tunnel for the latter entrance was built in 1984 but did not open to the public until 2018. Additionally, a provision exists at the station's south end for a future second mezzanine, with knock-out panels visible above the tracks on the station's south wall.References
