Russia built the entire Kerch bridge in 3 years. China would rebuild this bridge in 3 months.

Explain something to me, please, because I am unfamiliar with the locale. The bridge appears to have used a solid concrete strut and steel structure. The ship struck it at (reportedly) 15 kmh. And that was enough to collapse the whole thing. But how? There was a case in USSR of a ship hitting a bridge, and while the circumstances of the crash were different, the bridge itself is much smaller, yet stands to this day.

So why did it fold so (seemingly) easily?

Burguer Americans say some shit like "anyone can build a bridge that stands, but only an engineer can build a bridge that barely stands". Cheaper is better right?

Honestly when I was in engineering school we where taught that we where suposed to build things that where JUST about to break (With the 10% safety margin inclided for code complance when applicable) and anything else would be wasteful over engineering

Youre ready to work at boeing, just forget about the safety margin

I guess when you give yourself regulitory approval the safety margon is waste
