Herrenknecht S-210 on its way to Sedrun

Enlarged in diameter to 9.43m, the TBM faces 12km of hardest rock. It will pass on its way to Sedrun the Priora Zone, one of the most challenging hard rock formations of all.

The start of the S-211 (identical in construction to S-210) in the western tunnel Faido-Sedrun is planned for autumn 2007 in the western tunnel. The Gotthard Base Tunnel will be with 2 x 57km in length the world's longest traffic tunnel. At the Gotthard Base Tunnel the mechanized tunnelling of the main tubes is exclusively done by Gripper TBMs from Herrenknecht. By now, they have driven a total of almost 50km.
