Why would it spontaneously collapse like it was demo’d hours later, and not during the ‘transfer of force’?

EXCERPTS:

The Ludendorff Bridge (sometimes referred to as the Bridge at Remagen) was a bridge across the river Rhine in Germany which was captured by United States Army forces in early March 1945.

Midway through Operation Lumberjack, on 7 March 1945, the troops of the 1st U.S. Army approached Remagen and were surprised to find that the bridge was still standing.

After the U.S. forces captured the bridge, German forces tried to destroy it many times.

It finally collapsed on 17 March 1945, 10 days after it was captured.

Many structural factors involved. Eventually, weaknesses add up. The foundation shifts just enough, and just like that, a series of things happen.

"Spontaneously" collapse? It was on fire - burning - for many hours. Structural integrity tends to weaken when something is on fire and burning...
