Having said that, I wouldn't underestimate the hatred that Ukrainians have for the Kerch Bridge. Taking it out would be *the* victory as far as Ukrainians are concerned, although I'm fairly sure that Russia has massively over-engineered the bridge to resist attacks. It is surprisingly difficult to destroy bridges in war, too.
I disagree. Destroying some types of bridges from a long distance away may well be rather difficult. But if Ukrainian military forces gain control over Crimea, the days of the Kerch Straights Bridges will be numbered.
How difficult it is to make a bridge unusable, or to destroy one section of it, does depend on the type of bridge, the construction method used, the quality of the design and the quality of the workmanship. And it also depends on what weapons you have available. There are far too many variables in play, so making accurate predictions without all the relevant information is foolish.
I will however say this. If a military is determined, and has suitable weapons available, no bridge is safe from being seriously damaged or partially destroyed.
All bridges have points where they are relatively weak compared to other parts of the same structure.
I’m not a structural engineer or a bridge engineer. But given the length of the Kerch Straights Bridges, the position of them and the cost of building them, I would be surprised if they had been over engineered by any significant amount.
Back before computers, before engineers were able to fully simulate and calculate complex systems, structures like bridges were often over engineered for their intended use, simply because it was not certain if they would survive. And no one wanted a bridge failure.
But in the modern world, bridges, especially long, expensive bridges, are subject to very careful design. Again, no one wants a bridge failure, but at the same time these are extremely expensive, so costs have to be kept to reasonable levels.
That is not to say that the Russians took some limited precautions to make destruction more difficult. But “massively over-engineered the bridge to resist attacks”, I think not.
On a slightly unrelated note, the situation in Lyman continues to be interesting. Most people thought Lyman was going to fall quickly, but it seems that the Russian defences there have proven to be more resilient than elsewhere. There are also reports that Russia is literally throwing mobilised men into the front lines, which, if true, is nothing short of insanity. The thing that isn't clear is exactly what's happening there, although it seems that the battles are taking place around Lyman rather than in Lyman itself.
It looks like the Ukrainian forces are going north of the Lyman area, and are trying to cut it off in this direction. Leaving, for the time being, just the eastern side of that area under Russian control.
The question is, has Putin ordered all his forces to stand and fight? And if so, how many will continue to obey these orders as the threat of being encircled increases…?
Will there be another rout?
