【Share】Swiss complete world's longest tunnel
|
|
15 October 2010 Last updated at 14:23 GMT Engineers have drilled through the last remaining rock to complete the world's longest tunnel, under the Swiss Alps.  Imogen Foulkes describes the scene as the drill breaks through the remaining wall of rock The 10m-diameter drill-head tore through the rock to cheers and applause from watching workers. The 57km (35 mile) Gotthard rail tunnel has taken 14 years to build and is not likely to open before the end of 2016. But it is expected to revolutionise transport across Europe, providing a high-speed link between the north and south of the continent. Eventually, trains will travel through it at speeds of up to 250km/h (155mph). Journey times between Zurich and Milan are likely to be slashed by as much as one-and-a-half hours. The event, which took place shortly after 1415 (1215 GMT), was broadcast live on Swiss TV and watched by transport ministers across Europe. |
