- The Baltimore bridge collapse has many in the Philadelphia region wondering: could something similar happen to any of the major spans in our area? Read more: 6abc.com/baltimore-bridge-col...
The reason...money. The bridge was neglected for years due to a lack of funding and attention from the USDOT who actually owned the bridge. The bridge was actually supposed to have been replaced in the early 2000s when it was realized it was in critically bad shape, nor could it handle the traffic that headed over the bridge every year, but they opted to only rebuild the bridge with no upgrades including pier protection. In fact, that work just finished about 5-10 years ago. It's just another victim of decades of infrastructure neglect in this country.
@jhmcd2 Bridge authorities stated that the bridge was conforming to safety standards. It is very confusing.
Fenders to protect the main pylons would have been a very small fraction of the total cost.
@jhmcd2 But some authority (I heard it on the radio) stated that the bridge was
up to standards.
Of course, standards change with time and as new knowledge is gained. And nobody bothered to say to what standards codes or rules the bridge was conforming to.
Bottom line: People talk lightly about serious subjects and that is not doing any good.
We also need to know how the ship lost power. This ship has a history of mishaps.
Fake news. It was all fixed on Infrastructure week. Need to MAGA HARD in 2024. Dictators get things done!
This warning was brought up for years after the Sunshine bridge disaster.
hence the need to be reminded by that dude with the speech impediment on national TV
So I was in the Navy for 11 years and what strikes me the most from this tragedy is the absence of tugboats guiding this massive ship out to sea. Where are they? Where's the Pilot? Tugboats are there for this exact scenario. This is a fail at the very miniscule foundation of navigation, and maybe even engineering. RiP.
Two harbour pilots on board.
Official officals:" The bridge was in satisfactory condition. " A.K.A. it was still up, the design was flawed, the steel was cheap steel from overseas and the ships crew was diversified.
Or was it on purpose???
Totally agree, I too have piloted a U.S. Destroyer, one thing that seems weird is watching the video, how it looks like it just makes a hard turn into the bridge. It almost looks like in the videos I seen it appears to speed up and turn. They would most likely have a specialized harbor master from that port to take it in & out to begin with. And I gotta imagine there would be several redundant systems in place for a ship this size.
Anchor was dropped on the starboard side of the ship, that's why you see the hard turn into the bridge. @@restoreamerica1558
What protection system on the Key Bridge ? Hello !
Those were precisely some of my first thoughts on watching the incident unfold - that surely there should be some form of structural redundancy whereby the collapse of one span doesn't transfer to the others.
I see what you're doing dude. You're trying to get us to forget about the boeing whistleblower murder
You're just deflecting from the attack of 6-14-17.
ok.. did anyone notice the little flashes on the other pier to the right? the top frramework and at the point it parts out and the bottom where the road kinks,, if you look carefully there's puffs of smoke too. this was no accident
I was amazed when the entire bridge collapsed ... and also noticed the lack of protection around the supports. Food for thought for when rebuilding ...
The fact that the entire bridge collapsed is no big surprise given its construction. It's a Truss bridge, meaning the tension is holding it up just as much as the supports. If the middle collapses, there's no tension holding the other parts up.
Also the ships going under the bridge in Baltimore are HUGE. I'm not sure there is any concrete work that would have stopped such a ship. It would certainly have to be way bigger and stronger than what they showed on that other bridge. That stuff would not have stopped this huge cargo ship.
Somebody thought it was a good idea to save a bag of nickels and provide no safety for the bridge.
I’m glad they are asking this question because that was the first thing I noticed when watching this video….because every bridge I’ve been around has some type of barrier in place and something is very wrong that this bridge did not.
Over 100,000 tons moving at 8 knots. Really? Where is Michio or Neil when you need an intelligent assessment.
I was on a U.S. destroyer for years who’s top speed was just over 30 knots, which is a lot smaller and a lot more maneuverable, 8 knots is a pretty good clip for a huge ship in a crowded harbor and a real impressive for a ship that of that size that lost power. I would suspect they would have many redundant systems too. And that size ship would take forever to make a turn that’s why you typically have tugs when docking. A lot a unanswered questions including that billowing large plume of smoke from the stacks just prior, that doesn’t look to be just a backup power generator to me? That’s a lot of smoke for a power generator of any size.
@@restoreamerica1558 Huge diesel engines like those on the Dali use a huge amount of compressed air to get them started. That volume of air blowing through the pistons and stacks dislodges tremendous amounts of accumulated soot when the engine is started. ;-)
Follow the money... 1/2 to 1 million per bridge pier was saved by surrounding them with concrete islands to stop something with the massive weight of a ship. The standoff on the bridge protection was about 6 feet on this pier. Other piers have NO standoff or protection at all. The protection on adjacent power pylons is about 1000% better, perhaps even enough to have been effective. Seen this before, same problem, no pier protection. fyi the bridge in Philly noted, had protection, guess what, the next one, a rail road bridge, did not have anything to fend off more than a medium sized barge.
This bridge was built in the 1970s, but you’re right that people don’t wanna spend money on something. Spending money to reinforce a bridge does not get you applause from voters.
@russell7489 Transmission line towers do not have any protection except in extremely unusual circumstances and in those cases the protections are designed for those particular locations. The concrete islands are of a typical design and are supposed to fit most cases like steel bollards on sidewalks.
The major thing is 1977 the bridge was built and the Tampa Bay Bridge collapse in 1980 made clear what was important so why the heck was that not applied nation wide ??? Government is here to blame ...... 2 disasters of which the 2nd could have been avoided .......
Or is it people not wanting to pay taxes to maintain and improve infrastructure! But your point is taken!
@@waynehanley72not a single dime of tax money is used for infrastructure. Governments in the USA steeling your money of it's citizen's with bond's instead.
Baltimore, 18th busiest port in America. The bridge didn’t seem to have strong enough,stout support piers and no additional supports, an accident waiting to happen. Is this type of bridge design could affect other ports within the United States
You got to be kidding me about those little round cement circle are going to stop a 90,000 ton ship.
"little"? Look into how some of that stuff is made.
So you’re an engineer?
this commenter graduated from Walmart lol
@@gavinrolls1054 awe come on, you know he didn’t graduate. 🤔🫢🤦♂️
I can not imagine what the guys working on thr bridge endured
it is continuous system but when the impact is so strong, maybe a strong vibration is transmitted in whole system? I mean any lateral displacement of the system may cause a rupture in other parts?
It is a cantilever bridge. That clown has no idea what he is talking about.
This video gets right to the main point. Bridges spanning ship channels must be protected against allision from ships.
Who's Allison?
In case ship hits the fan
Don't you mean when the ship hits the span?!!
All this time I thought the lack of product would be when the shit hit the fan? They were wrong, it’s when the ships hit the dams, damn auto correct. 🤦♂️🤔🫢
Why was the ship so close to the pylon? It was deliberate. Seems they would be extra cautious, especially in the dark.
🎯
Those little concrete barriers won’t stop a freighter coming in at an angle. False sense of security.
How do you know?
@@Fredrick-jj9ok ahh, a ship just knocked down a bridge…
@@zeke5491 ahh, did that bridge in Baltimore have concrete barriers? 🤦🏻
@@Fredrick-jj9ok watch the videos - very small on both sides of the pilings
@@zeke5491 which for all intents and purposes may as well have not existed. Relatively tiny and insufficient wood and collar barriers - especially the distance they were from the piers made them useless
Another " Monday morning quarterback"? Now all the Experts speak out! This term originated in American football and refers to someone who criticizes or gives advice about a game after it has been played. In the News world, a Monday morning quarterback could be someone who provides commentary or critisism after the fact.
I doubt The protection that was shown on the other bridge would stop a mountain of a ship from destroying that bridge or even the GW if it hit the piers.
This shows exactly how much the US Govment really cares for it's citizens
If the underwater part of these concrete structures is comparable to the surface part, then in Baltimore they would not have helped since the impact was at an angle.
I think the bow on that ship would have crushed the dolphins if not simply span over top them anyway striking the bridge, that's one big heavy ship but anything is better then nothing I guess.
The protection system must be sized for the situation.
What would happen in this case is that the steel reinforcements on the bow would have bent and broken, and the ship would ground itself on the concrete. At that point the dolphins become structurally integral to the ship, keeping it mostly afloat for a while, but the kinetic energy of the ship is dispersed into the ship's superstructure.
The dolphin turns the ship's own superstructure into a massive crumple zone. Even a really massive ship will struggle to do more than lovetap the bridge support behind it.
That is the reason why the supports are much lower than the bridge. If they were the size of the bridge, it is more likely the ship would crack the pillar in two and cause the pillar to fall onto the bridge.
My work here is finished! Captain Hindsight away!
Tired of all these “experts”… do they not realize how LARGE this ship is. That many tons moving at 9 knots, that close…nothings stopping it. Worse than hitting the bridge with missiles.
This shouldn't surprise anyone. With cargo container ships doubling and tripling in size over the course of just a decade, bridge and infrastructure safety should be scaling to match that. And it hasn't been. That's because these shipping companies are always more concerned with money rather than the impact an accident like one of these ships could cause. Were looking at numerous peoples livelihoods taking a hit because of this and the bill being footed towards the citizens for repairs.
everyone should read the Sara Logan REPORT OR DOCUMENTARY ABOUT WHAT REALLY HAPPENED TO THAT BRIDGE
Before anyone gets their panties in a knot please consider what the largest size ships that were coming and going from the port back when the bridge was designed over 50 years ago.
Excuse me? They easily could have installed the barriers long after that bridge was built. Baltimore Neglect, plain & simple.
I'd love to see your engineering degree! Easily huh? Lets see, can you tell me just how easy it is to build a barricade that can withstand being hit by a vessel that's 948 feet long and 157 feet wide weighing 95,000 gross tonnes or 190,000,000 pounds traveling at 7.4 knots at impact? I'll wait! Meanwhile once I have a better idea of the actual surface area of the impact site I can give you some accurate data as to how many pounds per square inch you plain and simple barricade will have to absorb. ;-) @@LadieKadie
Oh! I forgot to mention you have to build it in 50 feet of frigid water without interrupting one of the busiest shipping lanes on the East coast. Easy! 🙂
Consider, for comparison, the Columbia River Bridge at Astoria. It is a little older than the FSK Bridge and it has always had fenders to protect the main pylons. It's crazy that this bridge has nothing beyond the caissons that form the footing of the pylons.
Official officals:" The bridge was in satisfactory condition. " A.K.A. it was still up, the design was flawed, the steel was cheap steel from overseas and the ships crew was diversified.
Nobody could of forseen a ship 🚢 hitting something in the water.😮
Took NYS 7 looooong years to rebuild the tappan zee bridge (or former NYS governor bridge), wonder how long gonna take them to rebuild this bridge...
So these concrete dolphins are capable of stopping a 30M pound force? I find that very difficult to believe. That ship would roll right through that concrete, because the steel of the ship itself couldn't take that impact. So the ship would keep going and the upper structure would have struck the Philly bridge and knock it over anyway.
With all the ship traffic under the Frances Scott Key bridge, why were the supports left wide open to a collision? Who bought off on the design? HUGE error!
Error?
The bridge was installed to the standards at time. It is of adequate structural design for conveying the intended traffic. It was not unsafe, and in fact was safe for over fifty years.
With 100,000 ton ships going the normal travel speed of 6-10 knots, will it really stop them on a dime? I rather doubt it. A better solution would be for tugs to escort these humongous ships past the delicate bridges. The bridges were engineered for extreme vehicle support, but very little from a sideways collision.
In San Francisco Bay we have Escort Tugs- they accompany big vessels past the two big bridges to get out of the Bay.
Their safety tugs.
The tragedy is serious, but its outright laughable how everybody in the comment section is an expert on bridge construction as well as foundations and supports systems....its mind boggling
I'm not sure I'd be so confident about those dolphins given current container ship size. (It's pretty amazing that the Key Bridge had no such protection, though).
Official officals:" The bridge was in satisfactory condition. " A.K.A. it was still up, the design was flawed, the steel was cheap steel from overseas and the ships crew was diversified.
186,000 tons in motion is a lot to stop and these Bridges weren't designed for impact like this. Everyone sees better in hindsight.
Why are we asking this question now?
I'm not sure, but we appreciate your question.
To mislead the public away from this black swan event.
This was literally my first thought
Leave it to the news to create unnecessary fear...
Any word on the ship being sabotaged??
Abieyuwa looks like the guy who went to school in the shortbus but hes on nationnal TV lecturing you on basic bridge security mesures with a speech impediment at 40+ years old.
The professor should have been studying bridges specifically this one so he would not be surprised by something he is a professor OF.
DEI ?
You don’t think those behind this attack didn’t look to find this specific unprotected bridge? Many prophets said to watch for a black swan event soon with all the heavenly signs. Just wait until April 8th solar eclipse sign. this was after March 25 lunar eclipse
you forget the sun and it's sunstorms... could have caused the outage that occurred on the ship... and there was a sunstorm... hence some northern lights exactly around this time in Iceland when the volcano erupted, which was around the time of the collapse... just saying.
@@manuela9671 great point, forgot to mention that, but that Carrington effect will do a lot more damage than when it was just telegraph lines.
Big ship. Flimsy bridge. No surprise
This is stupid. It fell because a ship hit it. It don’t take an expert. Bridges are in danger from ships, not just collapsing for nothing.
Look up Red Heifer israel. We're being distracted.
Hows that build back better workin out for ya?
Country going to hell with democrats driving the bus
WAKE UP! This happened because the Ship lost power. We need to know what caused this ship to malfunction. This ship has a history of mishaps.
@@seveglider8406 Nope, it happened because biden sucks

It wasn't.
@@ICU-mw7su When did You conduct a comprehensive investigation of this disaster?
All those billions of tax dollars collected over the lifespan of this bridge was wasted on more important stuff instead of infrastructure.

It was built in 1977. So stop showing your lack of “capacity“, I will called it that to be polite.
Thankfully the bridge wasn’t new or you would blame DEI. But who know, maybe you still will.

*ALL AMERICAN 1977 STEEL!*
Very simple this bridge is very light and weak that's why collapsed
