Not an engineer, but bridge decks serve to distribute the load to the bridge pillars.
In this case, with the supporting box girders ripped open by explosives, that is no longer quite the case.
I'd be very queasy driving a point load such as a tank over this structure now, despite safety factors.
Separately, some of the images show a pattern of holes, presumably from submunitions.
The big hole may be from a unitary warhead, 95kg explosives according to the manufacturers website.
The effect would be greater if the bridge deck were not hollow, but even as is, I think the bridge is militarily a writeoff.
