It seems to me that one of the difficulties we have built into our high precision weapons mentality is losing the notion that although a surgical strike with a mere 300Kg charge will take out a nasty Ayatollah and his house it simply can't deal wth a bloody great bridge - to the extent that we've lost the ability to take out bloody great bridges at all.
We've seen that multiple strikes from tube artillery all making one meter holes at one end of a bridge merely leaves the bridge standing, damaged sure but probably still useable.
Busting bridges requires dropping entire spans, not making 1m holes in the road deck.
The first try on the Kerch bridge did just that. And having seen the extraordinary structure of the bridge no wonder a boat bomb took it out, for that is surely what was did the job.
Next trick; to get another similar charge under the other span. And then to see that the next flammable train burns properly and melts the railway too...
