Design decision

Specialists veneer the floor and walls with granite, and in the technological premises they begin to lay brickwork.

Finishing work has begun in the interchange tunnel between the Maryina Roshcha stations of the same name on the Lyublinsko-Dmitrovskaya and Bolshaya Koltsevaya Lines (BKL) of the metro, said the Deputy Moscow Mayor for Urban Planning Policy and Construction Andrey Bochkarev.

“The transfer hub will connect two deep-laid stations of the same name on the Bolshaya Koltsevaya and Lyublinsko-Dmitrovskaya lines. In the pedestrian corridors, granite floors and walls have begun to be faced, and brickwork has begun in the technological rooms, ”he specified.

BKL passengers will be able to make a transfer along the corridor that leads from the central hall of the station. “Passengers will climb the stairs in three pedestrian walks to the level of a small inclined passage, along which escalators will lead them to an intermediate hall, from where they can again go up the stairs to the station of the Lyublinsko-Dmitrovskaya line,” Andrey Bochkarev explained.

Sergey Zhukov, General Director of JSC Mosmetrostroy, specified that work continues on the small inclined course of the transfer, where four 30-meter-long escalators will appear. Now they are putting up supports.

“At the beginning of spring, we will begin the installation of drainage decorative umbrellas, after which we will move on to the installation of escalators,” he specified.

For the first time, the delivery of escalator sections will be organized through the shaft through the distillation tunnel, and the installation itself will be performed from the bottom up. This is due to the design features of the interchange hub for stations constructed in a closed way at a depth of more than 60 meters.

Maryina Roshcha station is being built at the intersection of Maryina Roshcha 3rd passage and Sheremetyevskaya street. This is the deepest BKL station, it is being built at a depth of 70 meters. “Maryina Roshcha” is part of the northeastern section of the BCL along with “Sokolniki” and “Rizhskaya”. It is planned to start the train traffic in 2022.
