The cast-in-situ structures of the interchange bridge between the Tekstilshchiki stations of the Tagansko-Krasnopresnenskaya line and the Big Circle Line (BCL) of the Moscow Metro are being installed, according to Mr. Andrey Bochkarev, Deputy Mayor of Moscow for Urban Planning and Construction.

The Mosinzhproekt Group of Companies is a general designer and general contractor for the construction of new lines and stations of the Moscow Metro.

“The construction of the interchange bridge that will connect the new BCL Tekstilshchiki station with the same name station on the Tagansko-Krasnopresnenskaya line is underway. The construction of the bridge interchange includes two cast-in-situ stairs and a metal span. Currently, the construction workers are erecting the retaining walls and the foundation of the first support made of bored piles and monolithic grillage”, noted Mr. Andrey Bochkarev.

According to him, the Tekstilshchiki station of the Big Circle Line of the Moscow Metro is a key linking element of the emerging multifunctional transport and interchange hub.
“A unified large-scale infrastructure is being created on the base of the station, integrating the intensive passenger flows of underground and surface public transport. The future bridge will provide a comfortable interchange for more than 20,000 passengers”, specified Deputy Mayor.

According to Mr. Konstantin Maslakov, Director General of MIPSTROY 1 (the leading construction division of Mosinzhproekt GC), the sliding spans method would be used to construct the bridge interchange.

“The main bridge span is a prefabricated metal structure, with a total length of 140 metres. The central span will be installed using the sliding spans method, whereby parts of the metal structure are slid along the bridge axis by using traction equipment – hydraulic jacks”, informed Mr. Konstantin Maslakov.

He also added that the pre-assembly activities would be made to accelerate the work: individual elements of the span would be assembled into larger segments on a special slipway site. The preparatory work for the subsequent slipway is now underway.

The BCL Tekstilshchiki station is located between Shosseinaya Street and the tracks of the second Moscow Central Diameter. The bridge interchange of about 140 metres will be above railway and connect the northern concourse of the Big Circle Line station with the concourse of the Tekstilshchiki station of the purple line.

The eastern BCL section includes four stations: Klenovy Bulvar, Nagatinsky Zaton, Pechatniki and Tekstilshchiki. The eastern section is 11 km long. Its opening will improve transport accessibility for a number of districts in the southeast of Moscow.

The construction of the Big Circle Line is the main project of the Moscow Metro construction. Its length will exceed 70 km, and it will accommodate 31 stations, 22 of which are already open to passengers. The Big Circle Line will connect the existing and future lines of the Moscow Metro.

On 30 December, Mr. Sergei Sobyanin, Mayor of Moscow, performed a technical launch of the eastern section of the Big Circle Line of the Moscow Metro.

“Congratulations on a great event in the Moscow Metro, the completion of the last section of the Big Circle Line, which is the largest project in the world of circle metro lines and the largest project in the Moscow Metro history”, stated Mr. Sergei Sobyanin.
