tunnel

Construction of the world’s longest rail tunnel has finally come to an end, 16 years after predicted by the Swiss engineer who envisioned the project.

Carl Eduard Gruner came up with the idea in 1947 and thought it would be complete by the year 2000. Numerous delays led to the tunnel only being completed this year.

The tunnel is 57km long and runs under the Alps, connecting Zurich to Milan.

It cost just over 12 billion Swiss francs ($12 billion, 11 billion euros) to build and involved 2400 workers.
