I think I've seen a similar video of somewhere in the Netherlands.
However I think it more likely that on the bridge and immediate approaches, the overhead wire would be replaced by a rigid overhead bar.
There's a swing bridge on the railway at Trowse, Norwich, electrified at 25kV using a rigid bar. Like the one in this thread, it's single track.
If and when Selby to Hull is electrified, the Selby swing bridge will become the first double track, overhead electrified opening bridge on the mainline railway in the UK.
A previous generation of trams used the Trafford Road swing bridge at Salford/Old Trafford.

That slip didn't seem to be in the plan I'd seen (here). It is somewhat better with that, though I'm confused as to why they didn't just leave the existing slip in and have the new link road coming in at the position of the revised slip. I suppose this may be to prioritize M60Sb->Trafford Centre movements though it's quite an extravagance if that's all it's achieving. I also don't really see how there will be space for the slip and the link road unless the roundabout is getting expanded, which it doesn't seem to be from that plan.
I don't think I have ever been more confused by or have greater difficulty getting hold of accurate plans than I have for this scheme...
I suspect Highways England don't want to see all the exiting Trafford Centre traffic dumped on at J11 in close proximity to J12.
However, that whole area will never work properly due to overdevelopment and lack of infrastructure. Something will have to give, either the motorway is substantially widened or traffic is restrained. The nightmare scenario for traffic planners as neither option is politically popular.
Bryn Terminally cynical, unimpressed, and nearly Middle Age already. She said life was like a motorway; dull, grey, and long.
Does that mean the northbound on-slip at J10 will be retained, with the effect that J10 remains full access but J9 will only have access to the south via the new lifting bridge?
If so that does make sense, particularly for Trafford Centre traffic, but I expect the new bridge will be very busy indeed from day 1.

As I understand it, yes.
but J9 will only have access to the south via the new lifting bridge?
Do you mean J11? This will abolish the ultra-short southern tapers at J11 where it's adjacent to Barton viaduct. However it will add to the congestion at J10.

It will though I think they are hoping that some Trafford Centre (and vicinity) traffic will bypass J10 by getting off the M60 at J11, using the lift bridge and turning left down Trafford Way (the yellow DC in the drawing connecting three roundabouts).

Yes, I do - brain evidently not in the right gear.

You mean the bridge on what is now the M60? I knew six men were killed during its construction but I didn't know it was in one incident or that the incident was a collapse.
Construction deaths were not uncommon in those days.
