Baltimore bridge collapses into river after being hit by cargo ship
A portion of the Francis Scott Key Bridge in Baltimore has collapsed after a large boat collided with it early on Tuesday morning, sending multiple vehicles into the water.
At about 1.30am, a vessel crashed into the bridge, catching fire before sinking and causing multiple vehicles to fall into the water below, according to a video posted on X.
“All lanes closed both directions for incident on I-695 Key Bridge. Traffic is being detoured,” the Maryland Transportation Authority posted on X.
Matthew West, a petty officer first class for the coastguard in Baltimore, told the New York Times that the coastguard received a report of an impact at 1.27am ET. West said the Dali, a 948ft (29 metres) Singapore-flagged cargo ship, had hit the bridge, which is part of Interstate 695.
All lanes no longer in existence on I-695 Key Bridge.
They're still in existence, just a little wetter than usual.
That's not very typical, I'd like to make that point.
Well how is it untypical?
What about the environmental impact?
For the uninitiated:

Seven people likely dead so far. What a horrible, terrifying way to go.
I've heard it was construction workers filling pot holes.
The bridge at crest is around 185 ft off the water, and footage shows the collapse took about 6 seconds where the cars were.
Imagine doing a mind numbing job in the dead of night and then all of a sudden the floor starts dipping below you. The street lights go out a second or two later, and not long after you're falling for close to 2 seconds. Then either crashing hard into the concrete below you that just parted the water, having a flood of water hit you shortly after. or just jetting directly into freezing cold water.
How the fuck did this happen?
You’re making your regular commute, a bit annoyed with the sudden traffic backup, and then you’re suddenly falling with no warning, then struggling to not drown in your car.
It’s insane how everything can go from normal to terrifying. I hope those who lived through this have help coping, and am sorry for the victims and their families. It’s so tragic.
Nah, I'd say that it's probably fast and even if you're alive and conscious after you hit the water, you're gonna drown pretty quickly. Probably one of the better ways to go.
Dying generally isn't all that pleasant.
Drowning has to be towards the bottom of my list of ways to die
Drowning after falling from a great height.
Yeah I would expect vehicle occupants to have serious injuries after a fall like that. Water can be plenty "hard" enough to break your back if you hit it with something flat like a car
Drowning or fire? I can't decide.
I used to think drowning was the worst until I heard two accounts of people who drowned and were resuscitated. They said it was terribly peaceful. I'm good with it now.
I've heard this before but it doesn't make much sense to me.
Dying of a stroke in your sleep sounds peaceful.
Being unable to leave your submerged car because your back is broken, watching freezing water coming in, taking that last breath. Sounds fucking terrifying honestly.
It’s worse than that. People don’t understand what drowning is like at all, it is a terribly unpeaceful way to go. We all tend to think that you run out of air and then suddenly go unconscious but prior to that:
Water will enter your lungs which, fun fact, really don’t like that and so it is apparently extremely painful. It also triggers an involuntary reaction. You are now conscious on adrenaline, with very painful water in your lungs, and have lost all control of your body. Your body will attempt to flail wildly out of control while you suffer until you lose consciousness from lack of air. All of this happens quickly but probably not as quickly as you want it to given the circumstances.
Uh, source? It's a slow and scary death.
Just anecdotal. I think it was enough to not fear it so much. The recollection is that the bad part is you are fighting to stay alive but when you give in and swallow all of the you get a state of euphoria... so I figure if you've got no choice just suck the water in and die happy.
I sincerely doubt that your lungs filling with water would be "euphoric" considering any water in your lungs feels like burning. Even if the last seconds felt nice, you're discounting the terrifying minute or two of suffocation and panic.
That's like saying getting stabbed in the chest isn't a bad way to die because the pain sends you into shock and you pass out before dying
Whatever you tell yourself to help cope with your own anxiety about drowning I guess.. I nearly drowned and I can tell you it was not euphoric breathing in water.
Die happy. Yeah right.
Did you hear this in the prestige? Cause it was revealed he was lying
Nope.
I think you got bad information.
Not trying to defend him, but there are accounts of people who nearly/drowned in freezing water say they had feelings of warmth and euphoria. It’s likely due to shock setting in long before the drowning panic.
This wasn’t just drowning, though. This was drowning after likely sustaining significant impact injuries after hitting the water from many dozens of feet in a vehicle that basically belly-flopped, which is the worst way to impact the water. It’s like hitting concrete from that distance. And then panicking because you’re strapped inside your sinking vehicle.
This was anything but the peaceful drowning scenario you’re referencing that some people have.
I technically drowned when I was 12 and being an idiot 'riding' waterfalls. I got sucked into a big crack in a rock and when my friends finally got me out I was clinically dead, and all of my fingernails were ripped in half from trying to claw my way out. All I can remember is abject fear, and then the burning as my lungs gave up.
I would rather die by almost any other means.
Didn't die but passed out and had water in my lungs, didn't do same as you but went in the rapids in a river swimming during the summer as a kid, large amount of rain and a tree fell. Got sucked up under it and was trapped between the branches and the river gravel. Burning lungs and my face feeling like it was being drug across a cheese grater is the only thing I remember. Horrifying way to go.
How long were you dead for? How did they make you alive again?
My friends and I all took water rescue courses in cub scouts so they knew how to do mouth to mouth and clear water from lungs. One friend ran for help and the rest pulled me out and two did the mouth to mouth.
The EMTs who ahowed up after I was pulled out said they figured I was 'gone' for a minute or so. I don't really remember the exact details but it was something about the color of my skin that could tell them how long I was without oxygen.
Scary stuff - thanks for sharing the details, and glad you guys had the training!
Navy eod told me drowning feels like your lungs are on fire.
Reminds me of that story Michael Caine tells in The Prestige.
" Remember that sailor I told you about who got tangled up in the sails and drowned?"
"Yeah, he said it was like going home."
"I lied... He said it was agony.
Had a green beret buddy tell me the same thing. He had to go through a pretty intense water survival training, and part of it was “drown-proofing”. Said it was the worst part of his training.
Grandma told me once your lungs fill with water it's pretty chill. She almost drowned twice.
This was not a good way to go.
Agreed.. They had a bad day.
The investigation report is going to be interesting. While bridges can only take so much punishment, they are usually designed to survive some collisions with their pylons. I wonder what the state of the bridge was, prior to the collapse. If it's anything like the rest of the infrastructure in the US, it was probably not good. Though, this may also be a case that the designers in the 70's planned for a collision with a cargo vessel of the times, which were tiny bath tub boats compared to the super container ships we have now. The Dali was built in 2015 she is a 300m ship capable of carrying 116851 tons. That's a lot of mass for the pylon and it's barriers to stop.
I'm pretty sure no bridge is designed to survive a collision with a large cargo ship, even a brand new one. It would balloon the cost so much nobody would be willing to pay it.
New bridges are built with protections such as pylons to prevent ships from even getting close to bumping into the bridge after the sunshine skyway bridge collapse of 1980.
In this case I'm not sure it would have mattered. This wasn't a bump or a glancing blow. There's not much which will deflect or absorb that much energy head on.
I disagree, the geometry of protection dolphins use would deflect the ship enough to change its trajectory towards the walls of the channel bed where the ship would run aground before striking the bridge even from a head on collision.
What is a geometry protection dolphin?
They are concrete or wooden structures that are piled deep into the ground like fondation foundation pylons on skyscrapers. The geometry part I was just referring to how they are angled in such a way it ricochets the ship away from the structure it's protecting or towards the channel.
So why on earth didn't the bridge have these?
If I had to speculate? Cost savings... The bridge already had a history of cost reductions such as originally being built with a shared approach way which vastly increased the risk of head on collisions.
So in their effort to save money, they got 6 people killed and now have to spend presumably much more on a whole new bridge...
Possibly but you have to keep in mind this bridge was designed in the late 60s when a lot of the safety regulations that were written in blood hadn't happened yet. The Florida state sunshine skyway bridge collapse wouldn't happen for over a decade after the Francis Scott Key bridge opened.
A. It did, just only a few and the investigation will probably reveal not enough based on giant ships these days.
B. It was built before the Sunshine bridge collapse in 1980 so before the standards were updated.
I believe it refers to this: https://en.m.wikipedia.org/wiki/Dolphin_(structure)
This makes a lot of sense, thanks for the insight!
I suspect there'll be a lot of places taking a good long look at their current chunks of concrete they put around bridge supports and wondering how they'd stand up to the monstrous ships that are now the norm.
This kind of incident may not happen often but it does happen.
I imagine a lot of places may wonder about this and then kick that can down the road until someone does actually collide with their bridge.
!remindme 40 years.
A bridge is quite different to a pylon though.
Literally a block of concrete embedded in the sea floor.

It's* no tits
This is the absolute dumbest shit I’ve seen in a while. And it’s said so confidently, kind of amazing.
Why do you say that?
This structure was hit head on by a laden container ship. Container ships weigh between 50,000 and 200,000 tons depending on size and cargo. There is not a structure capable of being created by man which could sustain that amount of force, head on, and retain its structural integrity.
Buncha armchair idiots think they know more about bridge construction than civil engineers. Gods, this place is just more and more like Reddit by the minute.
Kinda crazy how those same construction and civil engineers are going to be investigating if the normal means of protection for this very foreseeable event was done correctly, because we design things to avoid these head on collisions:
https://wjla.com/features/i-team/questions-investigators-will-be-asking-about-francis-scott-key-bridge-collapse-baltimore-container-ship-collision-port-engineering-economy-shipping-hub
Also, not for nothing but even if they find out the dolphins in place were sufficient based on prior standards...this event will likely update the standards, same as the sun bridge in the 80s. Regulations and best practices are written in blood.
People always forget that deflection exists. I don't know why that guy is hung up on stopping the ship instead of just nudging it forcefully. If we can figure out a way to deflect explosions and sabot rounds, we can deflect a ship.
Yeah also just the basic concept of sacrificial parts and things designed to wear. The derailleur hanger on your bike, crumple zones in cars, plastic gears in your KitchenAid mixer - lots of engineering practices are designed around shunting failure to a particular piece or in a particular way, to avoid otherwise catastrophic or very expensive damage.
Oh my god! No way! They’re going to investigate and learn from a rare event! That’s shocking!
We study things all the time. Your extrapolation that an investigation means something was preventable is evidence that your higher brain function has been damaged.
You: "There is not a structure capable of being created by man which could sustain that amount of force, head on, and retain its structural integrity.
Actual engineers in the linked article: literally describe how to build secondary structures to deal with giant ships and prevent head on collisions on bridges.
I know you stopped responding but I'm piling on because I'm apparently in an impish mood:
From: https://www.washingtonpost.com/dc-md-va/2024/03/26/how-key-bridge-collapsed-baltimore/
It takes a pretty special kind of small mindedness to think that this accident will be uninteresting to engineers because container ships are simply too heavy to consider building against.
The amount of force needed to deflect a large object is much smaller than to stop it. In fact, if done over a large enough distance, a tiny amount of force is sufficient.
Need an example? Imagine your big brother is skating down a slope. Could you block him, head on? Probably not. But what if your sister, who was skating next to him, were to slightly steer him out of the way so that he doesn’t hit you?
As an alternative, you can also slow him down over a long distance, requiring the same(?) force but applied in a smaller amount, longer.
Because of a contradictory ass like yourself.
I live not five minutes away from the Key bridge and the sound of this woke me up last night. My GF takes this bridge to work every day. Driving through the city now for her every morning is going to be fucking awful.
I watched it on the news last night all the way from Australia and I said 'man they just fucked that whole cities traffic up for a long time'.
Yeah, IIRC it is the route for hazmat trucks. Gonna fuck with a lot of businesses down the line for a bit too.
As an aside, they used to have a rave down in the park under the west side of the bridge a decade or so ago, and it was always awesome being on the beach stage looking at that bridge at night and as the sun would come up.
The construction workers that died is fucking awful. The traffic situation won't be great, but at least she's alive with a job to go to.
Most people would take that as a given. He was just pointing out the effect on his own personal life.
It would be pretty annoying if everyone shared their own effect but had to precede it with a standard "I know it's more awful for those with lives lost, but this affects me because..."
Time to move. Or switch jobs.
Which is super easy to do. /s
If the traffic is bad enough you might not have many options.
Hopefully employers will allow WFH for jobs that can be feasibly done remotely. This will also help reduce traffic for those who cannot WFH.
But people do have dozens of jobs lined up at least, right?
Sounds like a problem for the people who use cars. Leg commute gang
I'm just glad it happened in the dead of night and that the ship sent a mayday several minutes before it happened. State Police were apparently able to close the bridge and clear most of the traffic (it's 1.6 miles/ 2.6 kilometers long) off of it before it collapsed. It's sad that there were still construction workers and some cars still left on it, though.
Crazy. Even with the mayday I'm amazed they could get police in position fast enough.
Hopefully police told the people to evacuate their vehicles
Unfortunately, it would've simply been faster for them to drive to either end of the bridge. The Maryland Department of Transportation had already closed the bridge. The only traffic left on the bridge was the traffic that got through before the closure, but everything happened so fast I don't think they had time to get off the bridge.
One article I read said that the mayday call, the bridge closure, the collision, and the collapse all happened in the span of about two minutes.
I'm so confused why a mayday wasn't sent out earlier though. Like they had to have known collision was imminent.
And weren't there local authorities on board that were guiding them through the waterway?
They lost power, dropped anchor, and called a mayday. By the sound of it the pilot probably did everything perfect. But whatever caused the power loss and engine failure is gonna be looked at very closely.
I think new procedures for having tugs hooked up until ships are entirely clear of port may be on their way - even if they're mostly just escorts unless the ship's engines fail.
There's gonna be a lot of pointing fingers and yelling, but hopefully in the end things will be safer than they are today. From the sound of it we got really lucky on the "lives lost" side of things.
Prolly something like:
"Aww nah, theres no need m8, I'm sure we'll figure something out"
I've heard the same thing with another issue
https://science.nasa.gov/climate-change/effects/
That’s the ship that hit the bridge. It’s still there as I write this, but there are a bunch of tugs on scene right now.
Marine traffic can show you all the active AIS contacts in real time.
Found a photo of the bridge on it.
Seems normal.
At least it happened in the very early AM hours when traffic was low and there were no visibility problems, unlike the Sunshine Skyway Bridge.
The fact that it was early morning probably saved hundreds of lives, from what I'm reading
That sounds like a traffic armageddon around Baltimore for the next few years...
Not just Baltimore. This is also a major cargo port. That harbor will be blocked for a long time. Get ready for supply chain disruptions and more rising prices.
I doubt the harbor will be blocked that long, maybe a week or so at most.
That's a crime scene and a death scene. It's not going to go quickly. The good news is that it's a critical roadway and waterway intersection so the feds and state government have motivation to make haste.
Except there is no mystery as to the deaths part. Investigations take a lot of time when there are a lot of questions. The only question here is "why did the boat plow straight into the bridge?". There's very little question how/why the bridge collapsed(it got hit directly by a massive cargo ship). No one's going to question the physics of it. The only question will be "was it captain error or ship error so we know who to fine". Recovering the ship will be part of answering that and the rest will be communication and maintenance logs.
I recently -- in the context of IS being in the somewhat bizzare situation of having to argue with the Russian government that they did in fact commit their terrorist act in Moscow -- linked to an old The Onion satirical video. It dated to a bit after 9/11 and had the Al Qaeda representative being interviewed -- irate at the 9/11 Truther also on the show, who was claiming that the World Trade Center was downed with thermite bombs -- using almost the same phrase:
https://www.youtube.com/watch?v=Q_OIXfkXEj0
"We flew an enormous airplane into a building, okay? I think it is obvious what caused the building to crumble."
The accident didn't happen in the middle of the navigable channel, so you can maintain the pier and ship while clearing the main span.
As for being a death scene, you likely aren't going to be able to access the site with divers as it is too dangerous.
I saw another article today where they said exactly that. The remaining vehicles are under concrete and its now converted to a salvage mission.
Good luck finding the necessary crane capacity. There are a handful of seriously big cranes in the 7000 tons plus range, but they are Dutch or Japanese, primarily. Wherever they are, they are probably busy and will take ages to get there. While the weight/mass of the bridge is not available online, it surely exceeds the weight limits of cranes currently in existence by far, so the bridge segments need to be cut up prior to removal.
Even if the US spends insane amounts of money, this issue will take quite some time to resolve.
The Left Coast Lifter is in NY and can be on site in about 24-30 hours depending on currents going up Delaware Bay. It can make picks up to approx 1,600 tons, it would laugh at what the Key bridge weighs.
https://en.m.wikipedia.org/wiki/Left_Coast_Lifter
At a 1,600 tons limit, one would have to cut the debris into a lot of small pieces. There is no info on the net on how much mass the Key bridge had, but assuming the build and the size, half a million tons is probably not to far off.
It won't come out in one piece, but it can come out in much larger pieces with a big crane. This one specifically was used to build bridges and put in far larger sections than this job would require. Smaller crane barges will work on the smaller pieces simultaneously. They'll clear half the channel (most likely the section away from the Dali) and open it to one-way traffic while they continue clean up.
You're not lifting it out of the way, you're gonna pull it out of the way with a tugboat.
It still is thousands of tons of steel, which will not be pulled that easily. And it is steel that does not swim, but drag along the muddy ground.
You cut it into pieces, add some buoyancy things. Naval operations can be impressive. Hell the Navy probably already has stuff to do this exact thing in case of war and a bridge out of Port gets destroyed. You don't want your Navy blocked in. You also don't need to move it far to get shipping back.
The "cut into pieces" will be interesting. There are a shitload of large pieces, and everything is under tension. The links between the pieces are rather large, and a good amount of them are under water. That's going to be serious work.
Feels like an army corps of engineer training exercise, especially after Biden committed to help rebuild. Be really interesting engineering coming out of both the cleanup, rebuild, and post accident analysis.
Cleanup will probably be Navy, rebuild will be civilian. Analysis is simple, ship lost power and hit the pier. Ships that size not sure you can do much.
I get the distinct impression that you have zero engineering knowledge or experience.
Or I'm trying to keep it concise.
Well, in that case you're being too vague because I have no idea what you are talking about.
not the original commenter, but they used some buoyancy things to lift a section of the titanic, obviously thats very different, but i think they are like large bags that can be filled with air to lift incredible weight underwater.
You mean the 14,000kg "big piece" that required two separate attempts to retrieve (by the same guy who piloted the doomed Oceangate sub)?
The floation bags were only necessary because the piece was on the bottom of the ocean beyond where any crane could reach. In some respects this seems to make the bridge cleanup a bit easier, but it wasn't the floatation bags that caused the first attempt to fail, it was the weight of the piece itself making it hard to capture with the class of tugboat they were using.
The second attempt succeeded only because they used this massive tugboat:
While the weight of the Key Bridge is not publicly known, it is likely thousands of times more massive than The Big Piece. For comparison the Golden Gate Bridge has a similar length of 1.7 miles (to Key Bridge's 1.6 miles), 6 lanes (to the Key Bridge's 4), and weighs 382,000,000kg. Assuming the Key Bridge only weighs half of what the Golden Gate does, it would weigh about 13,500 times more than The Big Piece. On top of that it is collapsed into a tangled mess and needs to be cut into pieces small enough to remove while it is underwater.
The resources needed to make this happen are going to be insane. It is going to take months before there's enough clearance to safely let more cargo ships through safely.
I think we all know someone who was forced to buy TP on ebay in the early pandemic.
This could send us right back there. Doesn't much matter why stuff can't move from A to B, prices will increase and people will take the opportunity to profiteer.
No. I don't know anyone, aside from Internet memes.
Do they ship much toilet paper by boat?
You can clear the debris in a week or two. It will take multiple years to build a new bridge.
The AP article says the exact opposite, that it is in fact not a major cargo port.
Vehicles from Europe coming via ROROs come to Baltimore primarily. This will impact them as diverting to Jacksonville or Savannah is going through take a lot of landside logistics to figure out.
If I'm not mistaken, it's Brunswick, not Savannah, that is Georgia's major port for automobiles/ROROs. Savannah is bigger overall, but that's due to other types of cargo.
This article mentions Brunswick having a goal of surpassing Baltimore, which is #1. I guess this disaster makes that more likely...
Port of Baltimore is top ten in the US for international trade. It falls to top 20 when domestic shipping is included, but it's absolutely a major port.
holy shit. I've been getting alerts about it, but that video is so much worse than I imagined.
That doesn't look like a little repair, which is what I had assumed. That looks like the ship's insurer is buying Baltimore a new bridge.
googles
https://en.wikipedia.org/wiki/Francis_Scott_Key_Bridge_%28Baltimore%29
The main span of 1,200 feet (366 m) was the third longest span of any continuous truss in the world.
Smooth.
So $143 million in 1972 dollars...
https://www.usinflationcalculator.com/
$1.06 billion in 2024 dollars.
EDIT:
https://www.vesselfinder.com/vessels/details/9697428
95k ton displacement.
https://www.imo.org/en/About/Conventions/Pages/Convention-on-Limitation-of-Liability-for-Maritime-Claims-(LLMC).aspx
So that'd be 29,200,000 SDR.
https://www.imf.org/external/np/fin/data/rms_sdrv.aspx
1.325610 US dollars per SDR.
So about a $39 million limit on marine liability for a ship of that size, or under 4% of the price of the bridge.
Maybe Baltimore taxpayers are gonna be buying Baltimore a new bridge.
EDIT2: I wonder how owners of larger ships managed to get lower per-ton liability limits than owners of smaller ships.
EDIT3: Oh, wait. Apparently the US isn't party to that treaty. Sounds like the US uses law even more favorable to the shipowner.
https://iclg.com/practice-areas/shipping-laws-and-regulations/usa
https://en.wikipedia.org/wiki/Limitation_of_Liability_Act_of_1851
I guess if you're gonna knock down a bridge with a container ship, the US is probably a good place to do it.
Color me surprised.
I appreciate the research and sources you've listed here. Its quite interesting from an impact perspective.
I am guessing these liability limits are for the cargo, not any damage caused by the ship. If shippers had to ensure everything they shipped for "storms and pirates" in the 1800's, then they probably wouldn't be able to do business. So there is a limit to what shippers would owe their clients if a ship got captured or wrecked. Those clients would need their own insurance if they wanted to be made whole in the event of a catastrophe.
What happens next is likely to be the result if the investigation. If this was a freak mechanical failure, and the boat's maintenance was otherwise up to date, then maybe the State won't be able to go after the boat's owners. But if there's any inkling that there was negligence in the maintenance of the boat, or in the piloting of it, the the State is going to go after the company for all it can. Depending on what they find, there might even be criminal charges.
The article about the treaty is explicitly talking about damage to things ships hit:
Ok, I stand corrected then. They're gonna have to sell a lot of crab cakes to fix that bridge....
Ahhh yes corporate arbitration lawyers. They shall be among the first to be flayed in the uprising.
I think that's probably way more than $39 million.
The Ever Given that got stuck in the Suez Canal was worth about $125 million carrying about $600 million in cargo. It had a capacity of 20,000 TEU (twenty foot equivalent units).
This MV Dali has a capacity of about 10,000 TEU and was carrying 4700 containers. I think no matter how you slice it, the value of the ship and its cargo would be in the hundreds of millions.
Feds are going to pay for it
The feds will front the money to start clearing the harbor and fixing the bridge as soon as possible, but I'd think that they're gonna go after the ship for whatever they can recover. They have whole offices of lawyers who go after liable parties for costs they end up covering.
Police audio from the event:
https://www.washingtonpost.com/dc-md-va/2024/03/26/baltimore-key-bridge-collapse-maryland/#link-SG74QTQZKNCI7CT3KCUCWYEZYQ
It sounds like police got their just in time to stop traffic. One of the officers says that as soon as backup arrives to take over stopping traffic he would go and evacuate the workers; when we get the report that the bridge is gone.
If you watch the stream of the crash, you can see that traffic was flowing just moments before it fell.
Wow, damn. Unfortunately similar to the Tasman Bridge collapse
May all involved find peace, that's so tragic.
I had to find a map, yeah, this is going to be a major cluster fuck in the morning. It's possible to route around it, but the next crossing is aways away:
Hazmats are prohibited in both tunnels. About the only option for those is to go all the way around 695, adding the better part of 50 miles.
I wonder how quickly one can get a RORO ferry up and running? That bridge isn't gonna be rebuilt any time soon.
Even the largest ferry can’t come close to matching the capacity of a 4 lane highway bridge.
No doubt. I don't mean to suggest that it'd eliminate issues.
Wow really? I totally can't believe that /s
No joke, and I bet it was heavily used too... Better jump on those infrastructure dollars!
Its not the same thing at all but they got the I-35W bridge rebuilt in 13 months after the bridge collapsed into the Mississippi. Its only 1/2 mile long and the river span is of course tiny -- no supports required in water.
There was a live-stream where you can scrub to the minute where the bridge is gone (1:28:43 by the time-stamp inside of the video, not the YT timestamp). The Ship apparently lost all the lights 2-3 times shortly before impact. Maybe it was a problem with that. We also noticed a lot of hacking activities in the last weeks. Maybe it was that.
Better to wait for more details to come out than to speculate wildly.
Idk I'm going with space lasers and you can't convince me otherwise.
A guy at work showed me the footage on his phone. Whatever shit news site he was pulling from had the headline, "DEI focus by The transportation department under Pete buttigiege results in bridge collapse".
They didn't even wait half a day to start lying.
Sigh.
Yeah, not everything bad that happens is intentional despite how much some people want that to be the case.
FBI confirms not an act of terrorism rn
Here's a quick take on the crash. Informed and conspiracy free, based upon the video:
Some speculation in there about the state of mind of the pilot in trying to explain their actions. Hopefully the NTSB report will shed more light on things. The state of the steering particularly.
It doesn't look like it was lined up right to begin with.
It was. Just a weird angle on the camera.
Wow, that was a wild shot of the collapse.
A portion? That looks like the entire thing dropped.
Everything in camera collapsed, but the whole thing was 1.6 miles.
https://en.m.wikipedia.org/wiki/Francis_Scott_Key_Bridge_(Baltimore)
That was pretty much the whole thing, looking at a Google Earth image of the thing:
Like, there are ramps over land that the cars drive up to get up to the bridge's full height, but what was in the image was more-or-less the portion that was over the water.
Ah I see!
Time for a redundant array of inexpensive bridges?
(computer joke about backups and resilience.)
Or on a more serious note, maybe a tunnel?
So which version of RAIB you thinking? Because obviously, this has to be hardware, can't do this with software. IMO, RAIB-5 is probably overkill but I think the locals would appreciate it.
I'm thinking RAIB-0. Not one problem there. No problems at all.
Just a Bunch Of Bridge.
I was thinking RAIB 10 . .no need for parity checking.
What sort of cabling, do you suppose?
Strong Cable Support Infrastructure?
RAIB-0 would be interesting enough. Each car split into equal parts across multiple bridges.
They also have a tunnel and other Bridges
There are two tunnels, plus you could go the long way around or on local streets. However there’s a lot of traffic, plus the tunnels have restrictions against hazardous or oversized loads
The Beowulf Bridge.
What kind of RAIB array would you suggest?
Looks like most crossing upstream are tunnels.
They are, with restrictions for hazmat, propane, and similar materials, so another tunnel with the same restrictions would be a major headache.
will this close down one of the biggest ports on the East Coast? how will other ships get by?
Yeah DOT confirmed the port of Baltimore is closed to sea traffic, local truck traffic from port is still active so the closure won't be felt immediately. But it will be significant the longer it's closed. 9th largest port in the US.
Yeah they won't get by, in bound traffic will reroute to Norfolk, Philadelphia and NY until a plan is in place. I would guess they have the channel open in 2 weeks or less.
As soon as the investigation is finished, they’ll get on removing the debris. That area has no shortage of transportation engineering companies. I’m sure people from the governor’s and mayor’s respective offices are already reaching out to line up inspections and eventual bids. Once the investigation is over, their top goal will be getting the port opened up.
They aren't going to wait for an investigation.

Yes, and they won't for the moment.
That’s gonna cause some delays.
Well that looks expensive
The scale doesn't even come across in the video.
That bit you see collapse is half a mile long.
I think you mistyped this. It was a mile and a half long.
Man I wouldn't want to be this boat's insurance.
The bridge is just gone now, one tap and the whole thing fell like dominos!
It would seem most construction projects rely on a boat not ramming into it
https://en.wikipedia.org/wiki/Sunshine_Skyway_Bridge
Florida apparently isn't relying on that anymore.
Boat hulls can't melt steel beams
Just to illustrate the point, this is no "tap". A cargo ship like that hitting something is about the same momentum as 14 loaded Boeing 787s hitting something at 800 km/h, simultaneously.
283 million pound "tap"
Those constructions rely on all parts being where they are, otherwise the whole thing collapses. You'd need a different kind of bridge for the single stretches to be independent.
It's bad enough that the transportation infrastructure is falling apart across the country due to poor maintenance. But when the bridge was built in the 1970s, I don't think container ships that big even existed. It's the same problem with old roads and modern cars or old airports and modern jets.
I hope that whatever replaces the Key Bridge is designed to fail in segments and take a good beating before it does.
That would be extremely expensive. I think that money would be better spent toward getting ships to not hit the bridge at all.
The bridge knows where it is, because it knows where it isn't.
It didn't just collapse 'after' being hit. It was destroyed by the collision.
Well yeah, I don't see how it's wrong to say it collapsed after being hit by a cargo ship.
I have to agree, if the headline says, "Man dies after drinking Drano," nobody is under the impression it was a coincidence.
As an Engineer I am looking forward to seeing how this plays out on future construction as well as retrofitting of existing bridges. Not only that, but also Emergency alert systems on cargo ships and maybe a more redundant power set up? But RIP to all those who lost their lives. Tragic.
This has been a plainly difficult production.
which is a prime example of a why a bridge built in a shipping lane should be built to stricter standards that would prevent a total fucking collapse from a errant ship.
Your username is quite fitting.
"Bridges should be built to resist entirely predictable accidents"
Lemmy: "angry, incoherent screaming"
I feel like I'm back on Reddit
Eh, on reddit they'd at least have the balls to comment and reveal how fucking stupid their pro-bridge collapse arguments were.
For sure, and furthermore the city should have some sort of tugboats capable of stopping a rogue ship if it had time to give out a mayday. Just attach a line to the back of the hull when it enters the channel and give throttle in the opposite direction to halt it.
EDIT: People downvoting like "snort small ship not pull big ship, so dumb"
I saw this just now on goog-ul and the first thought was... two ships collided on the bridge? But ships don't even drive on bridges!
Achtually
It's gotta be the Dutch! It's always the Dutch. I've also seen the one where the boat swings up on a rotating platform. Freaking Deutch.
Us, we live in the land of bridges made for cars only.
If you're talking about what I think you're talking about, that's British.

They're a tricky lot, those ships.

EDIT: Though for at least some of those, they're smaller and the right term is probably "boat" than "ship".
