So that appears to be a case of the bridge "channeling" the ambient air currents to cause the roll over of the rear, likely lightly loaded trailer, that had a reduced air stream to keep it in line while moving vs say the leading trailer ( a flag in the wind is a decent analogy?), and then the bridge abutment became a useful bumper to correct the unfolding accident, and everything was then right with the world, except for changing the drivers underpants?

Main takeaway, never, never ride alongside a semi.
