So I see. How much further has the push got to go? I can see a bit of
fresh concrete pier in the near left of the top camera. Is the span going
to drop onto that?

No, that pier isn't involved. The bridge has a great big extension on
the front (the grey bit where it tapers), so what they've got to do is
move it so the bridge proper is on the current pier. But first they've
got to adjust the counterweights, move it until the wheels at the big
can go no further, adjust the counterweights again so the weight is no
longer on the wheels, and remove them, then slide it along again until
either end is balanced right on the piers.

(I was inexplicably given an invite to the viewing gallery by the TfL
press office, and so have been rubbing shoulders with the big cheeses
that came up with this scheme)
