Demolition at Baltimore bridge collapse site
HTML-код
- Опубликовано: 12 май 2024
- The controlled demolition of the largest remaining steel span of the collapsed Francis Scott Key Bridge in Baltimore appeared to be a success on Monday.
The demolition occurred shortly after 5 p.m.
Crews have been preparing for weeks to use explosives to break down the span, which is an estimated 500 feet (152 meters) long and weighs up to 600 tons (544 metric tons).
It landed on the ship’s bow after the Dali lost power and crashed into one of the bridge’s support columns shortly after leaving Baltimore. Since then, the ship has been stuck amidst the wreckage and Baltimore’s busy port has been closed to most maritime traffic.
Maryland Gov. Wes Moore and other leaders including U.S. Speaker Emerita Nancy Pelosi, and Baltimore Mayor Brandon Scott held a press conference Monday saying work to get the port back open is on track.
"We are now very close to fully clearing the channel. And we are already getting large ships in and out of the Port of Baltimore. Over the next week we are expecting about 30 vessels and barges at the Port’s public and private terminals."
Six members of a roadwork crew plunged to their deaths in the March 26 collapse. The last of their bodies was recovered from the underwater wreckage last week. All the victims were Latino immigrants who came to the U.S. for job opportunities. They were filling potholes on an overnight shift when the bridge was destroyed.
The controlled demolition will allow the Dali to be refloated and guided back into the Port of Baltimore. Once the ship is removed, maritime traffic can begin returning to normal, which will provide relief for thousands of longshoremen, truckers and small business owners who have seen their jobs impacted by the closure.

How long will the United States of IIssrraaeell build a new bridge?
The fact that the actual demolition looked so close to the renderings is a testament to the engineers and to the experts who placed those explosives and did those cuts.
Yeaaaa, science bxtchhh
It wasn't explosives, it was a controlled thermite burning. The charges only started the thermite burn
9/11 flashbacks? 🧐
You have to thank the crane drivers, the divers, the engineers & everyone connected to bridge who have been working very hard for this to happen. CONGRATULATIONS TO EVERYONE FROM NEW 🇳🇿 ZEALAND
Lol
And congratulations also to the specialists, I guess they must have been employing the same experts who organized the bringing down of the Twin Towers !
My prayers are with the families who have lost loved ones, and my heart goes out to those who are trying to get to work.
I've watched all the video of the blast presented, you are the only one that made a presention that was knowledgeable of what was going on and why. Extremely professional, thank you for your good work Mr. Scott Broom.
I thought the cutting wood analogy was excellent, very insightful!
@markholtdorf56 My Amazon Shipment is LATE!
Reporters are so stupid. Its best they don’t say anything.
Isnt he reading a teleprompter? Lol 😅
Outstanding Coverage! Made it about the demolition and the Dali crew not the media reporting the facts!
I work in film special effects. An average director might have asked for a big fireball too, but this was not lacking anything on the visual side.
Yes, I'd say the guys did a perfect job, my highest respect, but let's not fool ourselves...these professionals love a great visual kaboom as much as anybody else.
Yeah, cause the average director doesn't know any better.
I thin hollywood needs to up its game now regarding explosions. Ukraine and Gaza have taught them some lessons. You don't get fireballs, you get black smoke.
@@donepearce tbf they had plenty of examples for decades, it's just the culture of big gasoline vapor explosion is too prevalent in the industry.
The demolition charges used are Linear Shape Charge (LSC). These types of charges cut the steel like a knife with a directed concentrated force of a high-speed jet.
Yes cumulative jets move at like 12km/s depending on explosives used. Armor in warfare has never been safe since.
Thermite clown, thermite
They didn’t give their lives… their lives were taken from them.
Ehh
Who's them?
@@InsoSan The people that died.
@@bogey19018 It wasn't taken they lost it
@@bloopgoesdonald6045 Due to what? Hacking the GPS maybe? But it's all been brushed under the rug, spotlight must remain no DJT AKA orangemanbad.
That ship crashed into the bridge on March 26th - and it is still there. That's a pretty good indication of how catastrophic a situation it was.
that ship is also owned by Singapore , in case you don't know . United States is milking this for all it's worth . Another way to make United States stay United . It's alllllll politics from here on in
and the crew is still there - they have not been allowed off! They had to stay on the ship during the demolition!
I'm an I.L.A. member. Tell me about it, lol.
The bridge decking and pavement probably weigh more than the superstructure that was just blasted off the ship.
Yep. Way heavier.
Yes, the ship didn't even move or rise after the explosion. It's still planted on the bottom until they get the roadway off of it, which I'm sure will be a technical challenge.
Yes, but they are in piece, relatively easy to scoop up, I'd think. That metal structure was one whole piece
They probably need to dredge underneath the ship to break it free. I would imagine the ground stopped the momentum of the ship
@@brianb4501 It may float up on its own once they remove the rest of the pavement and parts of the concrete tower that is on it. I'd bet there is probably a lot of heavy debris down inside of it too since the deck is cut open. Then again, it may be suctioned into the mud.
To those that had stuff in those shipping containers...your shipment has been "delayed".
there goes my trump sneakers and bible ! dadgum it !
Or possibly ruined. I'm not certain any of the refrigerated containers were kept cold enough for the contents to survive. And a few containers were destroyed.
Well, a whole bridge fell on top of it.
Most was going to Sri Lanka. This disaster might cause some inflation.
The journalist covering this demolition did a masterful job of explaining important aspects of the event and some of the background considerations going into it. A refreshing change from what is often presented in these types of coverages.
my heart still goes out too familys that lost thier love ones and my blessings for the ones try go to work
Mine too. They never mention the men who died, only how important it is to “ get those shipping lanes open !” God forbid that good old capitalism be slowed down any.
I was pleasantly surprised when the on-scene reporter said he was standing away from the camera so as to not block the view. Not only that, but you back at the station didn't do what seems to be a perpetual news station thing and that is having the opaque text box telling us what is happening. Of course doing so then blocks whatever the videographer is trying to show us all. So thank you for the old-time news broadcast.
Except talking over the shrunken main shot, which was on a split screen whilst the detonation was starting to happen was kinda sucky...
What are you talking about? They missed the big screen shot. The on scene guy messed up the cue, and they only got a split shot. You must work for the station.
@@Caractacus969 To answer your last statement of your reply, I do not work for the station. I do not work for any tv station. I am not even in Baltimore. You want to bust their chops for the split screen, go ahead, I am with you on it. My point was that unlike virtually every other piece of news, stations put on-screen text blocks up and as a result block the image. I am sure that this station does it too with their other news segments. I don't even like seeing the logos on the channels, since those blocks the screen too, especially when the aren't so translucent.
Had a Chicago News station muff a controlled demolition doing EXACTLY that,switched away and obscured shot when it occured and missed it completely. They're still getting laughed at.
Lmfao and yet they still failed by not having a full screen shot with a 10th of the video covered up.
The reason why they said don’t expect a Hollywood explosion is because no Hollywood explosion is an accurate representation of what explosions actually look like, there’s no big fireball in real life as Hollywood actually uses a really small amount of explosives and many jugs of gasoline to create those big theatrical effects that the public has become accustomed to seeing from watching movies
Never say never. From watching the unprecedentedly ample footage of the war in Ukraine there are plenty of situations where it really do be like that. From tanks exploding, to fuel caches going up, to a recent vid of a soldier carrying gasoline...
You're right that most explosions aren't fiery, but there are plenty of situations where the target has lots of fuel or the weapon itself is designed that way like with thermobarics and incendiaries.
@@sntslilhlpr6601 dude your own comment exactly proved what I was saying because those examples you mentioned have secondary fuel sources to combust. Tanks burn and “Cook Off” like that in those videos because there’s a fuel tank and there’s munitions that burn and explode. Then there’s other vehicles that have fuel tanks or the soldier carrying gas, all secondary fuel sources not to mention possibly secondary explosions from munitions that the vehicle might be carrying or even grenades hanging from the soldiers vest, especially smoke grenades as phosphorus burns incredibly fast and hot in those situations. I’m aware of what it looks like because I’ve seen that kind of stuff in person, I’m a Veteran. Explosions are a chemical reaction that creates a massive pressure expansion and there’s very little fire and flash with Medium or High Velocity Explosives and anything that you see in those videos with a big fire or flash almost certainly has a secondary fuel or munitions source like gasoline diesel propane natural gas to create the fireball and secondary explosions are confirmation of ordinance on target and and you destroyed it. That’s why some of those Ukrainian videos of them hitting barns with small charges and then you see a much larger secondary explosion, they are targeting suspected supplies/ munitions dumps.
*It really depends on, what exactly is "being blown up"!*
After 10 years as a Artillery Chief there are munitions used that do create huge fires. Namely White/Red Phosphorus and White Phosphorus "smoke" that burn white hot and not the Hollywood red/orange. 60#+ of TNT/Comp B does create a small flash when detonated especially when on a timed/proximity fuse and not so much on contact,it helps FO's spot and call adjustment of fire
@@ronv6637 yes phosphorus actually has its own fuel source for that burning which is something I already pointed out previously in an earlier comment. However my point is correct that explosives on their own do not create a big fireball like most people think an explosion should look like because that’s what they see in movies and television. Now in this exact situation of demolition of the bridge, what was almost certainly used in this demolition was C4 or something similar to that because it’s a high velocity explosive used to cut where something like ANFO is a Medium Velocity explosive and is used to move something or crack something
Thanks for the coverage!

A gigantic and equally dangerous task executed with surgical precision and perfection. Kudos to all those dynamic intelligentia and geniuses that planned, designed and accomolished with aolomb.
Too bad your overly wordy attempt has so many mistakes in it.
Not aplomb, a bomb
Pretty standard demo work,no where near level of a controlled structure demo
2 months later and this is where we are, not impressed really. We live in a country packed with resources and skills, not sure why they are dragging their feet.
This was the best coverage and reporting on this that I have seen so far. I just wish you had been a bit better prepared for the exact moment the charges went off...not on a split screen at...
5, 4, 3, 2, 1. Thank you for you respect for the workers who lost not given their lives on this bridge. Great comments on the thread as well! 😎
Another reason for crew on the ship as least some times is under maritime law, Ship abandonment is defined as an event where the ship owner has ceased communicating with their ship for more than eight weeks. So as long as it sits in the water and can communicate from time to time with the owners, the ship and all the cargo (to be delivered if possible) is theirs. Leaving under orders from the Coast Guard or in other situations can complicate it. But in general, their presence ensure no one can try to file a salvage claim ever on the ship or cargo (though I suspect any such claim would fail).
I believe That is the reason for the tradition that the captain is the last to abandon ship
Basic leadership,never ask anyone to do anything you would not do yourself
Appreciated.
Great skills to the Engineers involved in the demolition and professional reporting by all at WUSA 9. Thank you John, Auckland, New Zealand.
Good coverage, video, and narration.
I can't stand that phrase "the six workers GAVE their lives in service [for all of us]" ... Actually, their lives were unexpectedly taken from them.
I'd been looking forward to seeing this and I wasn't disappointed. Every aspect of the channel clearing so far has apparently been done with a great deal of skill and some real courage on the part of some of the people that have accomplished this. I expected that there would be some serious injuries or deaths of the workers directly involved. Maybe the most skillful part of all this has it has been accomplished so far safely.
Excellent Reporting! Not the media presenting the facts, but rather the demolition and the Dali crew!
Very good at explaining everything! Now when will they be building a new bridge and how long will it take. People really need that bridge. Thank you for your excellent reporting!!❤
These victims, GOD Bless their souls, did not "give" their lives. They "lost" their lives. These victims did not go onto the bridge knowing that they would lose their lives.
I wanna show this to all the geniuses that think the bridge was initially brought down with explosives
Agree, tho I drove over that bridge 2-3 times a year (fastest route from NYC to DC) and it was a flimsy narrow thing that should have been hardened or replaced.
Hello Dali, it's so nice to have you back where you belong.
When it literally is "breaking" news.
It was an Explosion of Directed shape charges . It produces force in a narrow shape that shears the metal. The Military has used them forever .
And those workers didnt "GIVE" their lives it was taken from them. Give Means willingly .
Thank you.
Glad to see this get cleaned up and hopefully a new bridge and better bridge is built.
Kinda looks very suspicious ships hitting bridges, barge hits bridge dumping iolite, and planes crashing and having accidents on runways.
Whoever put an ad in the middle of the detonation, you are the reason people use adblockers, and you deserve a permanent check engine light on every car you drive
Not one word about the mysterious CARGO!
1. Not an implosion. 2. Nice camera angle, and decent audio. Thanks.
Think of it this way your news agency could’ve been on that bridge interviewing the construction crew when the disaster hit.
The USA should be very proud of the Army Corp of Engineers. They do incredible work for the country.
ohhhh stop lady. " They gave their lives "in service" to us." Really... They were road workers. Yes RIP but stop the antics
Being theatrical and ignorant is part of her job.
No disrespect, but they were 6 guys sitting in trucks, not storming the beach at Normandy..
Their lives were taken by an incompetent, careless, and criminal likely, shipping company.
Gotta finish clearing the evidence of the preveous demolition...
That must have been very loud for the crew that is living on the ship.
Michael Bay disapproves.😅
Bay would've sank the ship too
gotta redo it cameras weren't ready
The Party. Peter Sellers. Classic!
nooo nono NOOO !
LETS SEEE...
TAKE TWO !
Amazing the crew have not been allowed to leave ship yet and were still on board during demolition. Two months stuck on board!
Watching from Australia 🇦🇺
It looks like a half of a successful demolition.
I hadn't considered how much the bridge portion in the water would sink.
do they have all the other debris off of the riverbed other than this?
Apparently, they added a lot of ballast to the ship at some point earlier in order to rest the bottom of the ship onto the channel floor. This was to stabilize the entire thing while working in and around it. Now they can pump the water out and hopefully it will rise enough to back it up.
any info on the crew?
Any thoughts or plans for the new bridge?
Almost home.
Cool Thumbnail!
Great show I’m following from Malta Europe
Tony
It will be interesting to see how they remove that payment off the ship.
The road deck is on the ship deck! Maybe they'll try to pick it up by the remaining bridge trusses. Otherwise, I'd think they'll have to jack hammer up the road.
They're going to back up the ship real quick and leave the roadway there.
Kinda like the old tablecloth trick.
I'm just speculating here, but I'll bet they will "secure it" and remove it with cranes once the ship is in dry dock. I don't expect them to mess with it out there in the middle of the river.
@@seeharvester Heh!
@@NorthernChev That's basically what was stated by the guy representing the coast guard in an interview (abc 7 news).
Although difference being removing it after going to pier along with removing some containers(but leaving some for stability), then after doing some amount of repair work(that can be done there) the ship will go away for full repairs and such.
I think the blast went on and the bridge fragment fell off, not the blast went off and the bridge fragment fell off.
perfect example of hourly job vs. contracted job
They won't be able to float that ship unless the concrete lanes are removed..
Explosion - takes a tenth of a second. RUclips - I'm gonna put an ad right in the middle of that.
use a blocker
@@gorak9000 I do, was watching on my TV though. Can't there.
Right when the explosion started too...atleast for me. Literally you see 1 second of the blast then commercial
Hey hey hey, engineer here. We don't expect things to happen, we calculate what's going to happen and then we KNOW what's going to happen.
On plan A anyway...
so... what about the towers?
Hey hey, experienced engineer here, we never know what is going to happen because Murphy is always on the payroll...
Couldn't the containers have been offloaded and reloaded onto another vessel? Were there any perishables? Or just hard goods?
Yes, but the plan was to close down the port. The boat clearly crashed into the bridge on purpose. Mission accomplished!
Please there is no place for common sense when dealing with Government.
Some containers have been (near the bow), but it's hazardous work, and also probably the cranes that would do it are busy doing bridge-clearing. There may indeed be some perishables; if so, the ship should be still providing power to the refrigeration units on the refrigerated containers.
There were refer boxes on the ship. But it’s unclear if the electrical system has been functional. So I don’t want to be near any of these refer boxes when opened. It’s going to be gross!
@@rickdeckardbladerunner2049 no
Leslie, it hasn't been that long. "...it's been such a long time."
Bridge Fabricated in Pittsburgh PA. , a lot of structural steel from Historic USS Homestead Works, bought and. now in India same as crew ???Structural mill in India.
Dobra robota.
damn, it's still there?
just flew over this a couple weeks ago what a mess
It's an explosion, not an implosion.
What about the crew still imprisoned on the ship ???
Thermite in a sand mold will hit 2000 degrees in a nano second you heat the sections to that degrees and the steel is white hot and the bridge falls apart
does it an important bridge?
because i think construction for new bridge should have start now
It's not the beam structure that's the issue , though it had to be cleared first. It's the road bed and its structure that will take time to clear.
When lived in reno ,nev an old casino 20 stories was demolished..blast didn't go well fell on side.
Finally my replica Nike Air Force 1’s will eventually get delivered soon. Thank you demolition team!
The ship was leaving port
Where were the supervisors of the crew that was working on nnounced the bridge? They shut down the bridge but why were the workers not evacuated by their supervisor?
There wasn't time. They had something like 90 seconds between when they got the message to the police who were already at the ends of the bridge to shut down the traffic, and when the bridge fell.
They did try to evacuate. Sadly, it is the workers driving in the trucks while trying to get off the bridge that died. The ones not in vehicles actually survived IIRC.
The selective demolition was a complete success. Now once the small.pieces of steel are lifted off the bow, the water ballast will be partially pumped out to reflect the Dali, which will be maneuvered back to the pier, where it will eventually have all the containers unloaded.
High tide wednesday if it isnt stuck.
It was tragic that six people lost their lives at work. The news anchor didn't give them any respect. She said they gave their lives serving for us. No, they died in an accident at work, no fault of their own. They did not give-their-lives-serving-us, like as if they were first responders or soldiers. What a misleading mockery.
Mockery of who? It was a fine report.
What way to go you were talking over and had 2 screens going and we did not get to see the actual explosion
I worked in both construction and film work explosive moments, they are completely different from one another. In construction we only use a strict amount of explosive to get the job done, in tunnel construction the amount used is calculated by the hardness of the rock and the size of the blasted material that has to be loaded away. Use less gelignite and the lumps are bigger and then prove difficult to load, get stuck on conveyors etc. Cutting steel we use an explosive cord to split the steel along a defined path.
Film work we used a bracket with a wooden dished out cup to puncture tyres in Citroen adds, no flash to give the game away. In Bond films etc. a flash gel adds the flames and a small amount of explosive throws debris in the air.
It seams that every TV news team won't action with each news item they have. But this takes a lot of planning, dry rehearsals and cost's a lot, something TV crews hate spending.
I also had the job of showing reporters around large tunnel projects and would first give them an induction, a project description and then a tour. On one metro project I took the team down in a construction lift, much the same as passengers would use when using the completed tube line. The reporter though added his part. " As we descend into the bowels of the earth" It took me ages of walking into meeting rooms bars etc. Of hearing that phrase.
This news guy just said the Crew is on board cause would know what to do in case of emergency 🤦♂️🤦♂️🤦♂️🤦♂️
Picture in picture fail. you guys had ONE job. XD
Looks like a bit of the trusses didn’t blow. Still on the foredeck.
Yeah I noticed that to I heard the big boom from my house I'm about 15 minutes away
The crew also maintain the containers...for example, many of the containers are running refrigerator units with food in them, etc.
That bridge shouldn’t have been there.
Any word on the stolen cars on that ship?
How about the " crew" still on ship detained, cellphones confiscated for over 6 weeks!?
they're being treated with less care than the cargo. it's so unfair
It’s always better to be safe then sorry let these guys do there job and appreciate that the task at hand isn’t easy. Having had experience working with crane operators I commend the work they do day in and day out. May God watch over you and everyone involved with this operation.
That was actually a textbook demolition
How about you guys doing an investigation into why they were stolen cars in containers on that ship
Sadly not able to see it live, in person.
I do live a little under three miles as the crow flies from the bridge.
I watched local news and it took about 4 or 5 seconds for the boom to reach my house.
Imagine those standing just over 2,000 yards away.
it seems America has forgotten how to innovate and do real important things quickly and right
Sad to see construction demolished this. But it has to be done.
nice videos
1:51 This is from the Demolition Puzzle game, Teardown; as in Löckelle Teardown Services and the actual #KABOOM 2:10
Ship didn't move. Appears to have the same draft as before the blast that removed the bridge.
Ballast was deliberately weighing it down.
I saw that too! No movement whatsoever of the ship after the trusses fell into the water. Don’t know what to make of that, but something is screwy. I don’t think they could have put enough ballast on that ship to have zero movement after the trusses fell.
This whole incident screams of something we’ll-planned and executed.
Anyone with 2 brain cells to rub together can see that the ship turned directly for that concrete support.
We will never know the full extent of this “operation.”
So the establishment officially blew up the bridge now ?
Well that was a little bit of a dud.
One of the trusses stayed wedged into the deck of the Dali, it was supposed to slide off with the rest of the steel posts.
😂😂
@WildWildWeasel 'Well that was a little bit of a dud.'
Is that what your mom said when you were born too?
@@Hundr_ Hey dude, I've seen you around projecting your fears and insecurities on everyone in the comments, you should go get help instead before you get the cops called on you. Just saying 😉
I'd say not actually a failure in this case. those pieces can safely be removed now, without having to worry about the rest of it collapsing onto the deck, and that was the point of this operation.
@@SiblingCreature What keeps me thinking though, is removing that piece that got wedged into the deck, without causing damage that, for example, could cause another compartment at the bow to flood, thus making it harder to refloat the ship and pull it away from the canal. I had seen simulations where that piece would effectively fall with the others, but it did not go down entirely as I expected it to.
Great joy! Guys. Keep safe.
