Video of the last few seconds shows two short power-outages. Looking into navigational capabilities and redundancy of engines, power, anchor, rudder.. and that the last few seconds a significant right turn, with opposite ship anchor...
The steering of the ship at the last second, "mayday" call, was timed with explosive charges along the highway length, such that the entire thing falls.
This is psyop. FF. Nicely done, with stopping traffic at the last moment from both directions.
There were no explosive charges on that bridge. There were no explosions. The bridge fell because a really large ship took out its primary support. Gravity did the rest.
Even if this were deliberate, you don’t need explosives, and there would be no way to hide placing them on the bridge.
