Civic Center/UN Plaza station (often Civic Center station) is a combined BART and Muni Metro rapid transit station in the Market Street Subway. Located under Market Street between 7th Street and 8th Street, it is named for the Civic Center neighborhood and the adjacent United Nations Plaza. The three-level station has a large fare mezzanine level, with separate platform levels for Muni Metro and BART below. History BART service at the station began on November 5, 1973, followed by Muni Metro service on February 18, 1980. In 2005, the station name was changed to Civic Center/UN Plaza during celebrations for the 60th anniversary of the United Nations and World Environment Day. Additional fares gates to allow direction connections between Muni and BART (without having to go up to the fare mezzanine) were also proposed. Construction of a bike station on the mezzanine level began in December 2014; it opened in August 2015. The entrances on the southern side of the station were closed from April 13, 2020, to June 12, 2021, due to low ridership during the COVID-19 pandemic.

The first level is a fare mezzanine, with two Muni paid areas and two BART paid areas. The second level has a single island platform for Muni Metro, and the third level has an island platform for BART. The station has six street entrances along its length. A passageway formerly led to two additional entrances west of 8th Street and Hyde Street. One – on the north side of Market Street at Grove Street – was temporarily closed in December 2016 after a sewer pipe collapsed under the escalators. The entrance remained closed until it was permanently removed in October 2017. The remaining entrance west of 8th Street was permanently closed on November 1, 2018, as the passageway space was needed for a new electrical substation to add redundancy and capacity to support increased Transbay Tube train frequency. The six original entrances (all of which are significantly closer to the faregates) remained open. Following the 2015 addition of a canopy over an escalator at 19th Street Oakland station, which reduced escalator downtime by one-third, BART decided to add canopies to all downtown Oakland and San Francisco entrances. The canopies will protect the escalator from weather damage, improve lighting, allow
