Yes but we know cantilevered bridges just fall down. Without in depth knowledge of the bridge itself no expert can decide on this.
In any case he seems to be looking at it as a military operational target. Not as circumstantial events accumulating. I bow to his affirmations about targetting things militarily I just don’t think he’s thought outside that box enough.
I don’t think this is the massive blow that it is being made out to be. The Russians have a ready supply of materials, enormously long flat surfaces they can simply deploy to cross the span…

He claims that there must have been likely placed several shaped explosives on bride foundations/pillars below the bridge because one bomb won’t do on such bridges. It’s also possible a truck with explosives is used in addition to that, but he doesn’t think that would sink the bridge alone.

I think in this situation, it is very much walk softly and carry a big stick. Be ready, be seen to be ready, don’t provide any escalating threats that might unify Russian opinion, and steadily escalate supply of armaments to Ukraine.

We can clearly here see at least two seperate places where the bridge has collapsed, reinforcing the theory of several shaped charges.
The interesting bit is the destroyed train, which isn’t explained necesarilly by this. Therefore the theory of vehicle-bomb on top of everything else.
It must have been a very difficult operation. But it’s clearly not an accident

That’s a coup by the Ukrainians to harm that bridge! But what about the other passage on the south of the bridge, between Taman and Kerch? Is it operational?
I really was hoping someone would pick up on the Charles De Gaulle comment and reassure me NATO had already thought about this and sent some additional ones to the area.
There is piracy going on and responsibilities to take.
If there is just 1 aircraft carrier in the vincinity I find that extremely disappointing (even if it is more than what Russia has there)… At the same time French and UK are escorting Russian warships through the channel FFS make them do the big tour round ‘our’ territorial waters. That are so precious we have fucking fish wars over them!

From Geroman’s twitter (unfortunately seems like traffic has began over the bridge)
WoW, that truck was carrying something that got extremely hot. I take back all I said before, this is very mysterious. Something went on and some of those hot particles hit the train transporting fuel, is my new analysis.
So, finally no big deal? Traffic resumes on the bridge and everything goes on as before? Oh well…
Would you drive across that bridge now … knowing one side of it just fell into the sea …? 
How is the blacktop of the segment of bridge that fell so pristine if it was destroyed from the top? I realise part of it is not visible as its underwater but I would have thought an attack from above either by vehicle or missile would at least show us something, which makes me think this could only be carried out by explosives from below damaging the underlying support structure…
US 6th Fleet has the George Bush (Nimitz-class) and the attached carrier battle group in the Eastern Mediterranean, near (or in, not sure today) Crete. The new CVN USS Gerald Ford (1st Ford class) is deployed in the Atlantic (northeastern), with a NATO flotilla accompanying that battle group, conducting training exercises - not far from France, actually, between Spain and Ireland.

I’ve wondered since the start of reading your updates, why this Geroman person and all the other Putin cocksuckers don’t just move to Russia since they love the regime so much?

That could be well dodgy now. That bridge is probably pre or post tensioned and heat could do funny stuff to that over and obove what fire does to concrete. Fire and concrete don’t mix that we’ll, YouCan get the thermal problems you’ve already mentioned in the rebar but also the concrete itself with the aggregate expanding and the limestone products changing chemically. The rebar will also lose strength at high temps and same with the tensioning tendons.
No obvious deflection though.

No cantilever spans there as far as I can see. It’s a arch central slan with approach viaducts. Those viaducts may be (probably) tensioned so see comment above on that.
Knocking one out not that difficult, especially if tensioned.

Kind of nice for a change over my usual drivel.
For tensioned bridges if you take enough concrete away around certain parts, the bridge will literally try and fold itself in half. Scary loads
