the tunnel is not ifnished yet and has nto been sunk to the river bed so is it really underground, it wont be when it is finshed, confused now.
have a look at the pics to pass the time then....
some scaffold within the caisson for something....?
view up a access tunnels within the caisson.
the lowest floor level in one of the 3 ballast tanks, to be filled fo rthe sinking and floating (really?!) down river to loaction.
the 4 caissons that will result in the finished tunnel in their dry dock.
