In the 1960s, new radial lines connected the city's newly-built districts, including Cheryomushki, Kuntsevo, Nagatino and Kuzminki, with the Circle Line. The orange and purple Kaluzhskaya, now Kaluzhsko-Rizhskaya, and Zhdanovskaya, now Tagansko-Krasnopresnenskaya, lines (Nos. 6 and 7) were built.
In the 1970s, metro lines continued to extend towards city outskirts and also linked up inside the Circle Line. Therefore several new diameters were created.
