At Amsteg the constructors of the Gotthard Base Tunnel have reached a further milestone. Almost eight years after the contract was signed, the Gotthard Base Tunnel North (AGN) consortium has handed over the structurally complete tunnels of the Amsteg section to the owner, AlpTransit Gotthard Ltd. The Amsteg-Sedrun section is therefore now ready for installation of the railway infrastructure.
On Wednesday, December 9, 2009, acceptance took place of both of the completed single-track tunnels in the Amsteg section. The approximately 11-kilometres-long tunnels between Amsteg and Sedrun were thus handed over to AlpTransit Gotthard Ltd. on time and within the cost budget. Together with the already technically tested northbound tunnels at Sedrun, the entire tunnel length Amsteg-Sedrun is now ready for installation of the railway infrastructure.
Meeting the deadlines and the cost budget could only be achieved thanks to the great efforts of the employees of the AGN consortium, the Gotthard Base Tunnel North engineering consortium, and AlpTransit Gotthard Ltd.
Final breakthrough in the 57-kilometres-long Gotthard Base Tunnel is scheduled to take place in November 2010. A further 4 km remain for the tunnellers to excavate between Sedrun and Faido. In total, more than 93% of the approximately 151.8 kilometres of shafts, passages, and tunnels of the Gotthard Base Tunnel have now been excavated. Commercial operation of the Gotthard Base Tunnel with scheduled train services is expected to start at the end of 2017.
