Don't know where that is, to be honest.
Wiki gives a reasonable overview:
It is notable for being the only swing bridge in the United Kingdom to carry an overhead electrified railway track (25 kV 50 Hz). Other examples can be found along the Northeast Corridor in the United States; see for instance Portal Bridge, and the Galata Bridge over the Golden Horn in Istanbul. The power supply to trains is provided by an overhead conductor rail instead of a wire, and there are short lengths of overhead conductor rail either side of the bridge on the fixed approaches. There is a 40 mph (64 km/h) speed limit over the bridge in both directions as trains are about to arrive at, or have just departed from, Norwich Station.

The leccy for the overhead rail on the bridge comes through the bridge pivot, not by a connection in the overhead. There is a circuit breakers so when the bridge isnt proven closed, there is not leccy on the bridge. Dunno how the return works TBH

Am I right in remembering the overhead rail was originally old mechanical signalling point rods?

Hull will get electrified under NPR.
Usually you deflate the expectations of other posters but here you seem to be inflating them. I was under the impression that the IRP specifically avoided a commitment to electrify to Hull. Truss, during her brief reign, made such a commitment, along with going via Bradford and having a station there, but Sunak reverted to what was in the IRP.

On the electrification of Selby swing bridge, it's harder than Trowse because Trowse is single track, but I'm sure double track ones have been done elsewhere in the world.

I believe I've read on here that the cabin above the swing span was raised several years ago to provide clearance.

I think that was precisely what it did.

Though of course I note @Bald Rick has suggested that quite a few of the things either directly written in or inferred from the IRP are either wrong or out of date, so it would be fair for this to be another such thing.

I may well be out of date on this matter.

Could they not single over the bridge. But that would impact the station so would be difficult.

Isn't there a capacity issue with Hull, especially if Humber freeport becomes a reality. Certainly what I heard.
The line was recently resignalled wasn't it? Hull Station is massive, surely platforms aren't a problem. Maybe the depot is tight on space.

On electrification - how often does Selby (and isn't there another swing bridge on the line?) Open? If navigation isn't required anymore then running wires over it will be relatively straightforward.

A chunk of the line was resignalled. I think that was a cost thing as much as anything else though. There used to be an intermediate stage when you wanted to automate some level crossings and consolidate a couple of manual boxes, but nowadays it's straight on to a panel in the ROC.

The former Trowse Swing Bridge was twin-track, and twin-track swing bridges have been done elsewhere (e.g. Portal Bridge in New Jersey, Galata Bridge in Istanbul). I have heard it mentioned before that a replacement Trowse bridge would be fixed as the current bridge rarely opens, if at all, being as the water traffic on the Wensum has more or less dried up (pun intended) since the docks closed.

No, not even Hull will get electrified despite posters at the station heralding 'Full electrification'!
Bradford, Halifax, Hull, Middlesbrough, Rochdale, Sheffield should all have been wired 30 years ago IMHO as should Manchester- Sheffield and Leeds- Sheffield and possibly Newcastle- Carlisle. I guess whether any of them get done now is a very moot point given the finances

Well, Bradford (Forster Square) was electrified nearly 30 years ago and Manchester - Sheffield (via Woodhead) was electrified nearly 70 years ago! :D

At some stage Hull will be electrified, even if there aren't any current plans.

Im sure its a straight forward as putting some wires up (obviously ignoring the fact the bridge needs to open)

On a more serious point does anybody know if wires are to reach Hambleton ?

Ironically Ive also just noticed on Google Maps there has been a lot of new electric infrastructure built right next to the junction!

That's Hambleton Junction SFC (Static Frequency Converter) and Feeder Station - part of the ECML Power Supply Upgrade works - which will be powering the TRU OLE (albeit via Colton Junction). Work to commission this, along with other new sectioning cabinets at Colton Junction, Balne & Doncaster, and the new Feeder Station at York (Skelton Jn) are tied in with the works to energise the Colton - Church Fenton (i.e. Route E1) OLE, as the lead time for new grid connections is never short - even with a regional DNO rather than National Grid.

Of course, the size of Hambleton means that it should easily be able to cope with any electrical load between Micklefield & Selby too, but this is a problem for another Control Period.

And, of course for a period of time the CP5 TP electrification plan included Micklefield-Selby, so it's understandable that electrical infrastructure was planned on this basis.

If the bridge needs to open, then the wires need to be able to swing with it. This makes it a lot more complicated, have a look at Trowse for why.
Of course, they could do what happens at some places here in the Netherlands, and leave out the wires completely and coast trains across.

The other swing bridge in the area is Goole, which isn't on the same line but is still on a line linking Doncaster and the ECML with Hull (IIRC when the Hatfield landslip happened, Hull Trains diverted via Goole).
As others have said it isn't impossible to electrify a swing bridge, and being double track shouldn't be an insurmountable obstacle either. It's a bit of a "Standedge Tunnel" problem in that it seems like a bigger problem to those of us with a little knowledge, than it does to those with a lot of knowledge.

Re the recent discussion of the extent of previous OLE in the Colton Junction area, there are cab videos on the web from which it can be seen, for example between 4:40 and 5:40 on this York-Leeds journey.
