The English Channel Tunnel is known as “Le tunnel sous la Manchein” in France. It is a undersea rail tunnel under the english channel. The channel tunnel is connecting Folkestone, Kent  close to Dover of United Kingdom with Coquelles, Pas-de-Calais close to Calais of northern France. The length of the channel tunnel is 31.53 miles (50.45 kilometers). The lowest point of this tunnel is 250 feet (75 meters) deep. The undersea part is 23.5 miles (37.9 kilometers) long.

High speed Eurostar passenger trains, the largest vehicle of the world “Eurotunnel Shuttle roll-on/roll-off vehicle” as well as international rail freight trains pass through this channel tunnel. The cost of this engineering project was £9 billion which is 700 times more than the cost of Golden Gate Bridge. The boring through gigantic boring machines took three years to meet the center of this channel from both sides. The channel tunnel holds three individual transits. Two 7.6m diameter transits are used for carrying the trains and 5m diameter middle channel tunnel is used for servicing and emergency purposes.

    Nice information…Is this the same tunnel which, when constructed, was pushed from both sides undersea and finally able to merge the front ends in the middle ? Thanks…
