Tunnel
 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.
