“The Big Circle Line (BCL) is 88% complete in general”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction. Mosinzhproekt Engineering Holding is the operator of the Moscow Metro Development Program.

“Today, Sergei Sobyanin, Mayor of Moscow, has carried out the technical launch of another section of the Big Circle Line including three stations: Terekhovo, Kuntsevskaya, and Davydkovo. The stations are almost complete. We have to complete the installation of the equipment, a connection of specific systems, running the test of the section with technical trains,” noted Andrey Bochkarev.

According to him, the Big Circle Line is 88% complete in general.

“The northeast section is 86% ready, the east section is nearly 50% complete. The work in the west, southwest, south sections is finally coming to an end. The reconstruction of the Kakhovskaya station, which will reopen as part of the BCL, is nearing completion,” explained Andrey Bochkarev, also recalling that the last tunnelling of the Big Circle Line is being carried out, considering the tunnels of the BCL are 97% complete.

For his part, Yuri Kravtsov, General Director of Mosinzhproekt JSC, said that the tunnel of the link line to the future Aminyevskoye electric depot is currently under construction and tunnelling continues in the eastern section of the Big Circle Line.

“In the east of the BCL, there are giant 10-meter diameter TBMs, Viktoria and Liliya, linking Pechatniki, Nagatinsky Zaton, and Klenovy Bulvar by the double-track tunnels, and also two 6-meter TBMs, Olga and Elena, which are tunnelling single-track tunnels between the current Kashirskaya station and the transit chamber near the Klenovy Bulvar station,” said the holding head.

All tunnelling work should be completed on the Big Circle Line by the end of the year.

It is more than 70 kilometres long with 31 stations, 12 of which have already been opened to passengers, with 9 new stations and a reconstructed station to be opened by the end of the year.
