Temporary restrictions will be in place due to ongoing repair work at several Moscow metro stations along the Serpukhovsko-Timiryazevskaya line, specifically Mendeleevskaya, Chekhovskaya, and Tsvetnoy Boulevard. This information comes from the city’s transit update channel The Deptrans and was confirmed by the metro’s press office. Commuters should expect changes to how these gray line stations operate during the maintenance window.
Officials indicated that the changes will affect service from May 20 to June 9. During this period, riders should plan for altered station access and possible disruptions to normal transfer patterns. The operational shifts are intended to support essential repairs while minimizing overall travel delays for the broader network.
In particular, the weekend periods of May 20–21 and May 27–28 will see the section between Savelovskaya and Borovitskaya temporarily closed. The closures are described as temporary in nature, with the aim of completing the necessary work within the stated dates. Passengers should review route options and consider alternative transit paths to reach their destinations on those days.
Access to entrances and exits at Chekhovskaya and Tsvetnoy Boulevard stations will be limited during the maintenance window. Commuters are advised to expect crowding at adjacent stations and to use alternative lines when feasible. City officials encourage travelers to verify on-site arrangements before starting their journeys and to allow extra time for transfers if they must travel through this section.
Looking back, similar maintenance periods have occurred periodically on Moscow’s metro green and gray line segments. Back in November it was announced that the Zamoskvoretskaya line segment between Avtozavodskaya and Orekhovo would close for six months before reopening, an adjustment that effectively returned the line to normal operation once the works were completed. Transit authorities emphasize that such interruptions are part of routine infrastructure upkeep aimed at improving safety and reliability for riders. For those planning trips during these periods, keeping an eye on official updates from the metro and Deptrans remains the best practice to minimize inconvenience.
