I'd guess the critical piece is whether they can quickly rebuild the damaged support structure. It's in 30' of water, so they can probably dam it off. Demo and pre-design assessment could start in weeks. Replacement could start in...months?

Emergency replacements tend to skip most of the advance process. Like who care about fisheries, public opinion, funding debates, whether the bridge ought to have a bike lane and bus lanes, or whether to design a taller bridge to improve on the 185' air draft and its limitations on the cruise industry.

The bridge structure will take a while. They can probably pre-assemble some chunks and barge them into place. I'd be curious about whether that sort of thing can be a lot faster than in the 1970s.

But yeah, this will be out for a while.
