Opening of the Gotthard Base Tunnel

Seventeen years after the first blast in the main shaft, the world’s longest railway tunnel is officially being opened today, and Implenia is very much involved in the celebrations. Together with its consortium partners, Implenia built three of the five tunnel sections – Sedrun, Faido and Bodio – that make up the 57 kilometre Gotthard base tunnel.
