On the bright side the rig didn't hit either of the main suspension towers; those are where most of the time and effort of construction is. Replacing a section of suspended roadbed is (relatively) simple and fast, at least.

On the bright side the rig didn't hit either of the main suspension towers; those are where most of the time and effort of construction is. Replacing a section of suspended roadbed is (relatively) simple and fast, at least.

Suspension bridges require somewhat balanced loading on the towers to remain upright. With a cable-stay bridge like the one pictured, it's unlikely enough cables would get sheared to cause a major failure, but on a bridge with arch-shaped major cables supporting smaller verticals, a failure of one of the major cables on either side of the bridge can lead to a collapse of the entire structure.
