Obviously it's too soon to say what the replacement plan is, but the original bridge took 5 years in the 70s to build, so this is unlikely to merely be a medium term closure.

They've done emergency rebuilds pretty quickly in the past. It's certainly more substantial than St. Anthony Falls or I-40 OK, but if the approach spans can be salvaged, they may be able to rebuild within 2-3 years. Really comes down to if the feds can throw a ton of money at it.

For the purposes of TM, it's a long-term closure, but probably not worth removing that stretch entirely given the conditions. How did we handle cases like IN 912?

How did we handle cases like IN 912?

It was split, though it was created while broken (and reviewed and activated with the wrong bit missing!)

2015-08-03;(USA) Indiana;IN 912;in.in912;Truncated at north end from Riley Road to exit 5A
2015-08-03;(USA) Indiana;IN 912 ((West) East Chicago);in.in912wec;Extended at east end from US41 to Riley Road
2016-08-09;(USA) Indiana;IN 912 ((West) East Chicago);in.in912ham;Renamed as IN 912 (Hammond)
2020-12-24;(USA) Indiana;IN 912;in.in912;Extended at west end via rebuilt bridge and former IN 912 (Hammond) to I-90
2020-12-24;(USA) Indiana;IN 912 (Hammond);;Route deleted

For the Genoa viaduct collapse we removed the closed section of road, but there was talk of them not reopening it (there was, and still is, a longstanding plan to build a bypass).

I'm in favor of keeping it as-is. Don't remove the segment from TM.

It's worth noting that with IN 912, initially there weren't actually plans to replace the bridge.

Since this bridge will be replaced (feds have already said they'll cover the tab, even) I am inclined to treat it no differently from any other case where a bridge is closed for replacement, albeit this one was unplanned.

May need to adjust the alignment depending on if the replacement ends up being fully "in place" or not, but that's to worry about later. For now, no action.

I don't see any rush to do anything here.  TM is not intended for navigational purposes.  Unless it is decided somewhere down the line that there will be no replacement at all, I think it stays as-is in TM as a temporary closure.
