Or do you think Ukraine got wind of Russia transporting high explosives in a manner OSHA would not approve and took advantage of the situation?
Yes, I put this up about ten times, but worth it.
Some history/details on bridge removal:
Can Ukraine destroy the Kerch (Crimea) Bridge?

MY guess... several teams in the water and a slow barge passing by with unusual chambers in the hull for pick up and delivery. Watching the video of the TRUCK allegedly exploding... the flame front appears to rise from underneath.
Also, untamped HE even a downward-facing shape charge would NOT do great damage to the piers.
This is NOT like in the movies. Massive amounts of high explosives are required. Underwater work is slow. Underwater communication is difficult; more so in the dark.
I propose a toast to the very special teams... Slava Ukraini !!!
