Tools like ANSYS might help, but I have no clue how fast you could model a tangled, disorganized mess you can't even see. It's not like analyzing a new structure where all your design and parameters are known.

What train tracks are on the bridge? I didn’t use the bridge often, but I was pretty sure it was two lanes in each direction.
What this calls for , for a timely resolution is probably several companies .
There are lots of videos of salvage companies doing what they do, here is one of the USS Guardian being removed from the reef that it was stuck on.
Salvage of USS Guardian by SMIT Salvage
SMIT is considered the best. fwiw, they salvaged the Russian sub Kursk.
What a genius. Clearing the channel will be faster than building a new bridge.
Why do idiots always feel the need to spout off with idiotic things?
Figuring out how to disassemble a tangled pile of twisted members without collapsing the pile and killing more people is a difficult task. How do you do the engineering calcs on a twisted mess?
It is less than easy but possible.
Step one is get a complete view of the "tangled pile of twisted members." That will take time in murky water. Also, radar/sonar have a hard time with a tangled pile of stuff.
Once you know what you're dealing with, the calculations aren't too tough. Also, computer sims can help. They key is to find the stress points aka what is holding all the weight.
Step two is cut around those stress points. If you cut a stress point, the whole mess could basically go "boom."
Then you can lift. That's step three.
I am way simplifying the issues, but figure FReepers don't want a 10-page treatise.
To be fair, I've been out of the engineering game for a while (got into more biz stuff) so please forgive errors my fellow Freepers. That said, still remember a bit about it.

I don't have a clue either except to say it will take some time.
Yes, ANSYS and similar tools might help. But this is a mess.
Something nobody else has mentioned: one of those stress points might give way on their own at any time. Then the entire pile of steel will shift, possibly with massive force that would cut a person in half like they were made of tissue paper.
This is an incredibly dangerous situation. The forces involved are hard to quantify. Let's just say a LOT.
It already has two under the harbor. The older one predates the Key Bridge. The bridge carried trucks that were prohibited from using the tunnels. Now they have to go the long way around the Baltimore Beltway.
Tunnels, which Baltimore has, are fine for routine traffic. Unwise for hazardous materials.and impossible for some simply oversized loads. Bridge is most missed for those two categories. Both likely require special permits so review of state records should quickly establish the types, quantities and any special needs of them. Based on that review set up appropriate ferries to get them across the river. Let the routine traffic use tunnels or other routes. Currently idle port workers could sketch out what’s required in days. Might need minor work at each River landing and to link them with live ends of I695. Might require some revisions and repurposing for the floating part(s) but it needn’t be fancy. Do that work in Baltimore port while otherwise shut down. Needed draft for ferries can likely get around the current bridge debris field. Just functional and safe ‘enough’ for permitted cargo. Minimize red tape and regulations and you’ll get that important traffic moving again long before new bridge is possible. Bridge was tolled, ferries should be too. Might still prove cost effective to send a few cargos around the long way rather than beefing up the ferries too much.
It won’t happen before Buttieggeeg gives birth.
Let’s all face it. If Buttigieg were not at his leadership post as Secretary of Transportation, the bridge situation could have been much worse. Thank goodness he took firm charge right away.*
Exactly what does that cabinet post do? His budget was $17 Billion for the fiscal year 2022/2023. 58,622 employees under him. All with benefits plans.

He is consulting government analysts for predictions:
🔮
The port won’t take too long but I heard the bridge might take a few years. They might have to replace the underwater structure depending how much is damaged. Biden announced that the federal government will pay the entire bill to repair everything. That means it could take 10 years to finish.
The Weather Channel runs a series called “Deep Water Salvage”. One show had a large car carrier ship lying on its side - about the same size as the Dali - off the West African coast.
They brought in a chain cutting barge standing some 100 feet above the water; it used multiple chains to cut the ship into sections which were then picked up and barged off.
Your example below was tiny compared to the one cited above; I don’t remember the name of the company. But only major salvage companies can get the channel cleared.
Pete is one worthless mookabooker with zero accomplishments.that’s it.
He is a homo
That is his resume
The recovery dives were very dangerous. Not sure if I would have sent anyone down.
It’s just under 10 minutes. Who Is In Charge of the Salvage in Baltimore?
The contract to salvage the ship has been awarded to Resolve Marine .
The removal of the bridge has been awarded via the Feds to Donjon Marine.
The remaining portion of the roadway falls under the Maryland Dept of Transportation who is using the company Skanska .
So far these are the players up to this point. This is going to be challenging, what is not needed are politicians sticking their nose not to mention their sticky fingers into the money pot.
