“The section of the orange line will be temporarily closed for the ‘Marina’ tunnel boring machine tunnelling the Troitskaya metro line”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.
Mosinzhproekt Group of Companies is a general designer and general contractor to build new lines and stations of the Moscow Metro.
“The section of the Kaluzhsko-Rizhskaya Line from the Oktyabrskaya station to the Novye Cheryomushki station is scheduled to be closed from 4 to 8 November. The ‘Marina’ tunnel boring machine, which is constructing the left running tunnel from the Vavilovskaya station to the Akademicheskaya station of the prospective Troitskaya Line, has already covered more than 90% of the planned route and will pass directly under the operating tunnels of the orange metro line”, said Andrey Bochkarev.
According to the Deputy Mayor, it has been decided to temporarily suspend traffic on the section of the orange line in order to avoid any risks to passengers.
Yuri Kravtsov, General Director of Mosinzhproekt JSC, emphasised that during the closure, tunnelling in the zone of influence of metro facilities would be carried out in accordance with the approved schedule.
“We will carry out all the necessary work as quickly as possible, mostly during the weekend, so as not to cause discomfort to Muscovites and visitors to the capital”, emphasised Yuri Kravtsov.
The head of the engineering holding also pointed out that an action plan had been developed together with the services of the SUE “Moscow Metro” in order to minimize the risks during the work and to ensure full safety of operating and newly-built metro structures. The plan includes round-the-clock monitoring of the operating tunnels of the Kaluzhsko-Rizhskaya Line and the tunnel of the Troitskaya Line under construction.
“A complete survey of all existing metro structures located in the tunneling area had been carried out before construction began. After its completion, monitoring of the tunnels will continue”, said Yuri Kravtsov.
During construction, alternative ground transport routes for passengers will be organised – additional buses will run along Leninsky Avenue and Profsoyuznaya Street with stops near the stations temporarily closed.
The Troitskaya metro line, being 40 km long, will connect the platforms of the Moscow Central Circle (MCC) with the city district of Troitsk, going through the Southern, South-Western, Troitsky and Novomoskovsky districts of the capital city. The expected daily passenger traffic flow is somewhat 100 thousand people. About 1 million people live near the new stations, and several hundred thousand more work or study nearby.
