Assuming however that money was indeed an object - how would you rank these projects in terms of engineering difficulty, probable relative cost, What is most expensive? What is the lowest hanging fruit - i.e. best value? The biggest bang for our roubles - etc.etc.?

I think that is unanswerable until we know what, if anything, Northern Powerhouse Rail actually means. At one extreme a total bypass of existing infrastructure by all fast east-west trains would take some pressure off several of the junctions mentioned. At the other, it could divert traffic onto some of the existing infrastructure if that was chosen to be part of the NPR route.
The other worm in the can is the TfGM long-term idea for a cross-city tunnel. That would certainly be less disruptive and possibly be cheaper than grade-separating all those junctions.
The lifting into place of the arch over the Irwell is oldish news now, but I've found a new video of it by looking on Severfield's website.

And at this point I must formally withdraw from the conversation, sadly.

A few updates from Wednesday:

You can clearly see where the welding joints are (I assume that these will blend in with time):

I think in Chris's Salford Central pictures the second track from the camera will eventually be removed, leaving five.
Meanwhile here are a couple of pictures posted by jrb on SSC:

I am not sure if this has already been asked, but is that bridge constructed from weathered steel, for if it is, it will save on painting costs.

Useful article on the project here:

(Can't find a simple quote that summarises it)

As of 16:08 yesterday, there were 6 ties up on the network arch bridge, Overcrowding prevented any photo op.
From SSC, the first picture with strings:

The Northern Programme Twitter feed has pictures of the replacement beams for Chapel Street bridge, lying on the ground in the storage area near the Chord works.
Also the crane that will remove the old beams and place the new ones:

The demolition at Chapel Street bridge was done in 1hr 15mins according to the Northern Programme Twitter feed. It has pictures of work there and on the Chord (and at Penrith and Chapel-en-le Frith):

I went past at about 1015 yesterday, and it was still incomplete on the SE side, and possibly also on the NW side.
It's quite difficult separating the "strings" on both sides optically.

Am I right in thinking that services via the chord will be the only ones which serve a station in a city, then a second in a different city, then another station in the first city again, with no repeat mileage or reversals?

I don't understand what you mean, which services will do this?

Wires evidently an optional extra.
Presumably they will be up by this time next week for Northern to use on the Chat Moss stopper.
Also presumably the trackwork at the Deal St end of this is now complete for both Chat Moss and Chord routes?
That ought to mean no more route closures here until the Chord opens.
Attention will turn instead to the new junction at the Castlefield end, with more blockades needed there.

No, still a lot to go there. One point is in on the down but nothing for the up yet. Plenty more bridge construction work still to take place too
Edit:- the point I think is for a 5th track through Salford Central.

I presume they are referring to any service which will run Manchester Victoria - Salford Central - Deansgate / Oxford Road / Piccadilly

That is indeed what I meant. I'm struggling to think of any others that do so even with a reversal. I assume the Calder Valley - Airport services will call at Salford Central even if the TPE airport services won't.

Platforms at Salford Central will need to be reinstated. Suprisingly when the new formation was laid the railhead lines up with the original platform surface. You can clearly see this in my first image
Very nice 50anyday. Looks like you could take that curve at the end at 50 with those rollercoaster style cants! Also loving the European style style platform heights.
I think it was Joseph Locke that stated the reason for high level rails through Central is so that the entire chord is on one level, so the climb had to start around Deal St.
