According to the project, it’s planned to construct the combined (rail and traffic) road 49 km long.
Six Tunnel Systems are planned to be constructed along this combined road, including:
- 6 railway tunnels with the total length of 10 425 m,
- 3 traffic tunnel with the total length of 7 587 m,
- 3 service tunnels with the total length of 9 400 m.
The total length of all the tunnels - 27 412 km.
Taking into account the lengths of the tunnels, hydrogeological conditions and construction experience in this area, two methods of tunnel construction are panned to be used: roadheaders and TBMs.
