I stood on the Thames embankment yesterday, outside the old County Hall
Building, just below the steps leading down from Westminister Bridge. I
could feel the vibration of the Jubilee Line trains passing under the river,
between Westminister & Waterloo.

What did worry me a little, was a largish barge moored on the downstream
side of Westminster Bridge, close to its central arch They were driving in
some large steel tubes using a pile-driver. I began to wonder just how far
away from the tunnel they might be and how deep it lies under the river bed.

Anyone know what this is all about? I did note Westminister Bridge seems to
be undergoing either a good clean-up, or some maintenance work is taking
place. I would like to know what is ocurring in the river.

There is also another old and long disused tunnel running from the basement
of what was the New Scotland Yard building under the river. It is totally
flooded and was sealed many years ago.
