The Chunnel - World's Longest Underwater Tunnel

At its lowest level, it is 75 m (250 feet) deep. At 37.9 kilometres (23.5 mi), the tunnel has the lengthiest undersea section of any passage in the world, although the Seikan Tunnel in Japan is both much longer overall at 53.85 kilometres (33.46 mi) and also deeper at 240 metres (790 feet) listed below sea degree.

The passage attaches end-to-end with the LGV Nord and also High Speed 1 high-speed train lines. Concepts for a cross-Channel repaired hyperlink looked like early as 1802, [10] [11] British political as well as press stress over the compromising of nationwide safety delayed attempts to construct a passage. [12] An early attempt at constructing a Stations Tunnel was made in the late 19th century, on the English side "in the hope of forcing the hand of the English Government". [13] The eventual successful project, organised by Eurotunnel, began construction in 1988 and opened in 1994. At 4.650 billion, the project can be found in 80 % over its anticipated budget. At 37.9 kilometres (23.5 mi), the tunnel has the longest undersea section of any kind of passage in the world, although the Seikan Passage in Japan is both longer complete at 53.85 kilometres (33.46 mi) as well as much deeper at 240 metres (790 ft) here sea level. The rate limit in the passage is 160 kilometres per hour (99 miles per hour). The passage hooks up end-to-end doing the LGV Nord and also High Rate 1 high-speed railway lines. British political as well as press stress over the compromising of national security stalled attempts to construct a tunnel. An early attempt at building a Stations Tunnel was made in the late 19th century, on the English side "in the hope of forcing the hand of the English Government".
