Halfway there: Of the 153.5 km total of tunnel systems forming the Gotthard Base Tunnel, half has been excavated. To date, 50% has been cut with tunnel boring machines and 50% by drilling and blasting.
With a length of 57 km, the Gotthard Base Tunnel is the heart of the new Gotthard rail link. It is providing the infrastructure to implement Switzerland's strategy of transferring traffic from road to rail. The tunnel system under the Gotthard comprises a total of 153.5 km of tunnels, shafts and passages. Yesterday, half this amount had been excavated. Construction is therefore on schedule overall. Current plans are for first scheduled trains to travel through the Gotthard Base Tunnel at the end of 2015.
Some 1800 people from 12 nations are currently working on the five construction sites of the Gotthard Base Tunnel at Erstfeld, Amsteg, Sedrun, Faido and Bodio.
Construction of the world's longest rail tunnel began at Sedrun in spring 1996. Tunnelling from the north started at Amsteg in November 1999 and from the south at Bodio in July 2000.
