Location

Construction

The station is located under Stockton Street between Geary Street and Market Street. The main entrance will be on Geary Street at the southeast corner of Union Square. The south end of the station will be connected to the mezzanine level of the existing Powell Street station outside fare control.[3] The existing entrance to Powell Street station on Stockton Street at Ellis Street was purchased from BART for one dollar, and was temporarily closed in 2014 so it could be converted into a shared entrance to both stations.[4]

Station excavation was completed by July 2017, and concrete was poured for the station floor.[5]

Stockton Street reopened between Geary Street and Ellis Street on February 22, 2019. Muni route 8/8AX/8BX and 91 buses returned to lower Stockton Street and 4th Street on February 25; route 30 and 45 trolleybuses returned on April 13 after overhead wires were re-installed.[6][7]
