Gostiny Dvor
Admiralteyskaya was opened in 2011 between Gostiny Dvor and Vasileostrovskaya and became a transfer to Line 5. Proletarskaya was closed for reconstruction on August 25, 2005. Originally, it was intended to reopen on February 25, 2007, but the reconstruction was finished ahead of schedule, allowing the station to reopen on November 17, 2006.
