It moved again last night. The south end of the transfer deck is now centred over the supports on platforms 8/9. Is this as far as it will go for a while?
The post I just referred back to confirms that it will be held above P8/P9 for a while, the initial move was explained to be 28.5 metres. The gap between the P8/P9 piers and the P7 abutment is rather longer than the distance they've just covered, so I assume they need more weight on the north end now to balance that out.
In fact, having now looked at the webcam pictures, I'd estimate that the next gap is a bit longer than half the length of the existing structure - so it will have to be made longer for the procedure to work again, IYSWIM...
I think this could also be done by adding significantly more temporary weight to the north end as a counterbalance, but it probably makes much more sense to spend a little more time adding the normal structural steel, as that only has to be done once.
