Looks like they were setting the prestressed concrete beams when 3 spans collapsed. Few details right now.

Those piers are super slender. I wonder if there was a loss of support caused by the piers deflecting or twisting due to something like wind, crane forces, etc.

Were they bringing that beam placing machine out over a bunch of beams without a deck? Sure looks like the beams rolled over and then everything fell.

Yes looks like the beams rolled and then game over. Needed more bracing of the beams probably.
