I noticed yesterday that just under the City end of the Lower Lea
Crossing, there are some Works of some description, mostly a very
large Hole in the Ground. There is, of course, a protective barrier
surrounding these Works, and on them a notice reading "Crossrail
Line One, 24 hour helpline" and then a telephone number.

Anybody know whether this is really anything to do with Crossrail,
or just a useful piece of barrier imported from somewhere else.

It's certainly more or less over the planned alignment of the Crossrail
tunnels. It may be a test borehole to analyse the ground structure.
However, I would not expect that to produce a "very large" hole visible
on the surface. Is this just east of the roundabout where the Lower Lea
Crossing meets Aspen Way?
