Channel Tunnel is one of the Europe's biggest infrastructure projects to date. The $15 billion Channel Tunnel makes the old dream of a ground link between Great Britain and continental Europe a reality for the first time since the Ice Ages.
The tunnel consists of 3 interconnected tubes: 1 rail track each way plus 1 service tunnel. Total length is 31 miles, of which 23 miles are underwater. Its average depth is 150 feet under the seabed.
The channel crossing time with high speed train is approximately 20 minutes. Over 95 miles of tunnels were dug by nearly 13,000 engineers, technicians and workers. The volume of rubble removed from the tunnel is three times greater than that of the Cheops Pyramid in Egypt.
This tunnel has increased the size of Britain by 90 acres. Equivalent to 68 football fields, this area has been made into a park.
