It is planned to complete the BCL eastern and north-eastern sections in the current year.  In December 2021, the traffic was launched along the new 20 km long Big Circle Line (BCL) section of 10 stations — from Mnevniki to Kakhovskaya. Now there are 22 BCL stations in the Moscow metro.  Nine more are planned to be completed in the running year — the remaining BCL section is over 60 percent ready. Thus, the Big Circle of the Moscow metro will form a ring by 2023. The mos.ru article is about the next BCL stations.
