It was a failure of the crane’s cable, not the bridge.

I don't believe you are correct with the crane cable snapping as there was no crane on site when the bridge collapsed. If you look at pictures and video right after this happened there is not a crane within site. Not to mention it's not legal by any means to have a crane with it's boom over the road while it's open. This bridge was 100% supported buy itself and should have had a temp support mid span until the mast and cables that were intended to support the bridge were installed.
