The Channel Tunnel is a megastructure built to connect Great Britain to Europe.
The tunnel consists of 3 interconnected tubes: 1 rail track each way plus 1 service tunnel. Its length is 31 miles, of which 23 miles are underwater. Its average depth is 150 feet under the seabed. The channel crossing time for Eurostar is only 20 minutes. 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. And it has increased the size of Britain by 90 acres. Equivalent to 68 football fields, this area has been made into a park.
