Challenges Channel Tunnel

While tunneling the challenge of what to do with all of the spoils from the drilling came up. On Britain’s side approximately 5 million cubic meters of spoils had to be disposed of. They decided to simply dump the material back into the channel near the mouth of the tunnel, adding 73 acres of land to the island once the tunnel was completed.
