Lyublinsko-Dmitrovskaya metro line  - The new section of the Lyublinsko-Dmitrovskaya metro line will have 3 stations – Yakhromskaya ( with the working name Ulitsa 800-letiya Moskvy) , Lianozovo  and Fiztekh – all are planned to be opened simultaneously in 2023. 

At Yakhromskaya and Lianozovo stations, the retaining walls are ready; at Lianozovo, a transition to the MCD-1 platform is 97.5% completed. 

The running tunnels between the future Lianozovo and Fiztekh stations of the Lyublinsko-Dmitrovskaya metro line section under construction are 80% complete. The Tatyana and Irina TBMs have almost completed tunnelling to the future Fiztekh station. At present, both shields have already crossed the Moscow Automobile Ring Road. The left tunnel is 79% complete and the right tunnel is 77% complete. 

At the Fiztekh station, the preparation work for excavation shoring and utilities network relocation outside the construction footprint is underway. The enclosing structures for the Fiztech station pit are now 25% complete. The Fiztech station will be located along Dmitrovskoye Highway , north of Akademik Landau Boulevard. There will be one lobby with exits to the Dmitrovskoe highway, stops for surface passenger urban and suburban transport. Click here for further information. 

Big Circle Line (BCL)  

The Big Circle Line is the key Moscow Metro construction project, its length will be 70 km with 31 stations, 12 of which are already open to passengers. It will be the longest underground loop line in the world. 

Western section  

The construction of the main structures of the Kuntsevskaya station of the Western section of the Big Circle Line (BCL) is almost complete: architectural and finishing works are now 98% complete,  and the building of the passenger areas are underway. The station project will serve as an interchange to the stations for Filyovskaya and Arbatsko-Pokrovskaya metro lines and the MCD-1. 

The general construction of the second stage of the Western section of the BCL has reached 92%. In April, they opened the first stage of the Western section with Mnyovniki and Narodnoye Opolcheniye stations . Work on the Terekhovo and Kuntsevskaya stations is currently underway: the tunnels between the stations are now complete. The Western section of the BCL tunneling was carried out using both six-meter and ten-meter diameters TBMs: single-track tunnels link the Khoroshyovskaya and Narodnoye Opolcheniye stations, and a double-track tunnel has been constructed from Narodnoye Opolcheniye to Kuntsevskaya.  

Eastern Section  

Tunneling between the Pechatniki and Nagatinsky Zaton stations of the Big Circle Line (BCL) is now more than half complete. 

The 10 m  TBM Victoria has driven 904 m of the double-track tunnel between the stations under construction on the eastern section of the Pechatniki BCL and Nagatinsky Zaton , which is more than half of the total length of the tunnel.   

At the same time on the eastern section of the BCL, a double-track tunnel is currently under construction between the Nagatinsky Zaton and Klenovy Boulevard stations: TBM Lilia has tunnelled over 70% of its route. In addition the construction of  a single-track tunnel from the Kashirskaya station towards Klenovy Boulevard is underway.  

TBM Victoria has stopped at a specially equipped site to replace the cutting tools and will then continue under the Moskva River, which is 500 m wide.  

TBM Victoria has passed the Pechatniki which is a dense urban development zone .  Part of the tunnel passed directly under the Pechatniki station of the Lyublinsko-Dmitrovskaya line, and then under the sewer of the Nishchenko river. The route was difficult with mixed soils (from sands to limestones) which were heavily permeated with water. 

The Tekstilshchiki and Klenovy Boulevard stations construction has reached 50%, and architectural and finishing work, and the utility systems are all being installed. The Pechatniki and Nagatinsky Zaton stations are now one third ready - work continues on the construction of the main structures of the stations.  

Currently, 4 stations are under construction on the eastern section of the BCL: Klenovy Boulevard, Nagatinsky Zaton, Pechatniki and Tekstilshchiki Their commissioning will improve transport accessibility to the surrounding areas.
