Moscow will open the northern section of Big Circle Line in 2021 and the entire line is expected to be completed 2022, Deputy Moscow Mayor for Urban Development and Construction, Marat Khusnullin, announced.
In December, Moscow opened Big Circle Line’s Savyolovskaya station, the world’s deepest interchange station, located 65 metres underground.
Big Circle Line is city’s longest metro line that will have 70 km served by 31 stations two train maintenance facilities. It will reduce congestion on the metro’s first and second interchange circuits, that is, the Circle Line (No. 5) and the stations inside it. The line’s stations will open stage by stage and are expected to handle up to 380 million people annually.
For 2019, the city intends to complete 32 km of metro lines, 14 stations and two maintenance facilities. The first section of the new Nekrasovskaya, formerly Kozhukhovskaya, Line (No. 15) between the Kosino and Nekrasovka stations is to open in late March or early April. The section between the Aviamotornaya and Lefortovo stations is to open in late December 2019. There are also plans to open the Rudnyovo train maintenance facility, the first to start operating this year, in late March or early April.
Nizhegorodskaya station is the most complex construction problem because no other station like this has ever been built, Khusnullin explained. Some of the tunnels between it and the Kosino station have been built with a 10-metre-diameter tunnel-boring machine. This is big enough for both tracks in the same big tunnel. The tunnels between the Kosino and Nekrasovka stations were built with conventional tunnel-boring machines with a diameter of six metres. Nizhegorodskaya station will also connect with the Moscow Central Circle (MCC) railway and the Karacharovo commuter railway platform.
A 10-metre-wide TBM will soon move through the operational Stakhanovskaya station. The new metro line will link the Nizhegorodskaya and Nekrasovka stations through seven city districts, via the Moscow Region’s Lyubertsy urban community-settlement. The new stations will make things easier for 800,000 Moscow residents. The line will considerably reduce congestion on the metro’s Tagansko-Krasnopresnenskaya (No. 7) and Kalininskaya (No. 8) lines.
In 2018, Moscow opened 17 underground metro stations, building 33 km of tracks and three train maintenance facilities.
