as the northern branch of the Frunzensko-Primorskaya Line began, the underground vestibule of Admiralteystkaya was built, even as the location of the exit remained uncertain. By 1997, most of the vestibule was completed. However, the lack of resolution over the status of the station's exit, combined with scarcity of funds, put further construction on halt. When the northern branch was opened as a temporary part of the Pravoberezhnaya Line, the train passed the unfinished station without stopping, slowing down slightly while transversing it. However, in 2005, the construction resumed. Trains began to occasionally stop at this station in early morning hours to drop off workers. Transport Buses: 2, 7, 3, 10, 22, 24, 27, 191. Trolleybuses: 1, 5, 7, 10, 11, 17, 22. Architecture The station is connected to the ground with two consecutive escalators.
