When the line was built several areas were left with a straight tunnel provision for potential future built in of new stations. One of which was Gorkovskaya (now Tverskaya) between Mayakovskaya and Teatralnaya, which was opened in 1979. However several more remain: Sovetskaya between Tverskaya and Teatralnaya, Bega between Dinamo and Belorusskaya, Vishnyakovsky Pereulok between Novokuznetskaya and Paveletskaya and Moskvorechye (also referred to as Vasilyevsky Spusk) between Teatralnaya and Novokuznetskaya. The latter provision stands the highest chance of being developed as the vacant space caused by demolition of the Rossiya Hotel is likely to be filled with new office buildings and hotels.
