Ok, not the first tunnel, they have been on the South coast for hundreds of years. But this is one mega tunnel that must have taken a massive investment.
Eigth one since 2006 they have found, so how many more must there be?
Wouldn't like to be in the shoes of the the person that grassed them up today !
Apparently it's no that old. What I'm wondering is how did they come across it now when it is just getting used for transport but no one noticed it when they were digging the thing out?
