Metrostroy builders began the construction of the right running tunnel from the access chamber (№ 25.3) to the “Aviamotornaya” station of the Great Circle Line.

For 6 months the tunneling mechanized complex “Herrenknecht S-772” named “Tatyana” will have to walk 1 357 meters.

The route of the site will lay under the industrial and transport infrastructure of the Lefortovo district. The main difficulties will be associated with the tunneling under the railway tracks of the Kazan direction and the existing “Aviamotornaya” station of the Kalininsko-Solntsevskaya line. In order to prevent the sinking or skewing of the rails during the passage of the shield under the tracks, special safety packages are used.

Earlier, the German complex built left running tunnel between the exit and Lefortovo chambers, a left distillation tunnel on the northern section of the extension of the Lyublinsko-Dmitrovskaya line from the dead ends of the exit chambers to “Seligerskaya”, as well as the right branch of the “Likhobory” dead end access chamber in the “Okruzhnaya” direction.

In the first half of September, the passage of the right and left running tunnels from the access chamber to the “Nizhegorodskaya” station was completed.

After the completion of the construction of both tunnels of the remaining section, the total length of the run between “Aviamotornaya” and “Nizhegorodskaya” will be about 2.5 km.
