The longest Tunnel system 3 is located between the 23rd and the 28th km of the combined road including the traffic tunnel, the railway tunnel and the service tunnel of over 4 km each.
All the three tunnels are planned to be constructed using the most innovative technology at present time – by means of tunnel boring machines. For this purpose three TBMs were purchased from Germany and Canada:
- Herrenknecht 13210 HART (diameter 13,2 m) for the traffic tunnel construction (the tunnel length – 4034,8 m);
- Lovat RME 243 DS (diameter 6,2 m) for the service tunnel;
- Lovat RM 394 DS (diameter 10,2 m) for the railway tunnel – construction (the tunnel length – 4124,5 m construction (the tunnel length – 4055,2 m).
It?s planned to construct the Tunnel system 3 between: 2nd quarter of 2009 – 2nd quarter of 2013
