It also has to be remembered that it was designed and built almost 50 years ago, when container ships did not exist yet, and the cargo ships around were only 1/3 or less the size that they are today. Definitely a larger bumper area around each pier will be built around the replacement bridge.
The 2 Largest cargo ships in the world when the Key Bridge was built would have been only slightly larger and heavier than the Dali. these days, the Dali is almost boring by comparison in how average it is.
@@thecactusman17 Relax. It doesn't have to be 1000 years ago. Just in the last 20 years cargo ships have taken massive leaps in size. The Panama Canal built an entire new, wider and deeper lock system and ship builders designed cargo ships to come within inches of tolerance.
It's not the type of bridge. It's the protection for the piers. That's why bridges should be adequately protected with dolphins or similar structural protection.
Oh look, someone who knows what they’re talking about. Here I thought all the comments would be “it’s impossible to withstand a hit like that!”🤦♂️ they’re not completely wrong, but that’s why we build precautions to keep that impact from occurring in the first place…
Newsflash, if a ship that big EVER hits the foundation of your bridge head on - that bridge is collapsing. Check the stats on the cargo that hit them, it’s half as big as the fucking bridge itself. No bridge is built for that type of impact
This. These cargo ships are massive and weight hundreds of tons. The ship was only traveling 9 MPH when it hit the Key Bridge and it came down like it was made of tin fol. No bridge in the world can withstand getting hit by a ship like that unforutnately.
They had dolphins, but not in the right places. As far as bumpers directly surrounding the structure, they probably wouldn’t have helped much even if they’d been built.
I miss the days where my parents could hold me in their lap as they drive. Sometimes I carry my 6 month year old as a drive (safely of course), but it's a shame that California keeps changing and taking away things we love.
I'm also a civil engineer. I think the Key Bridge tragedy was preventable. The MV Dali was not under power when it hit the bridge pier. A bridge bumper or, if the pier was built into a relatively shallow part of the harbor, even an artificial island should have been present to protect the piers. The piers Coronado Bridge are vulnerable to ship strike the Key Bridge, except that San Diego does not have a large container ship terminal. The largest ships going under the Coronado Bridge are U.S. Navy vessels, including USS Carl Vinson (CVN-70), one of the warships homeported in San Diego.
Coronado Bridge is not high enough for a Nimitz class carrier. But even so I do not believe the bridge towers could survive a hit from one any of the Navies larger vessels going 7 kts., as the M/V Dali was doing when she struck the Francis Scott Key Bridge. Even with the bridge tower protections at water level, one of the smaller amphibious carriers (LHA or LHD) would still contact the tower with the overhanging flight deck, most likely causing the tower to fail.
@@captglenn100 - I was just pointing out that big ships only go under the Coronado Bridge occasionally. Compare to the Port of Long Beach/Los Angeles, where we are fortunate that the piers of all the high bridges over the navigation channels are on dry land, safe from ships.
If you look at Google Maps, you'll see that the in-service aircraft carriers and other truly gigantic ships don't pass under the bridge, unless they are reserve fleet and aren't expected to be deployed on short notice. The larger cargo ships in the port are all under 300m. Compare to the massive 400m+ container ships up in Long Beach, or what you'd find at the Marine Terminal in Baltimore, the Coronado Bridge doesn't have any truly large vessels passing under it under normal circumstances, mostly just reserve ships like retired aircraft carriers and a few oil transporters. Also, they can't get up to full speed in harbor before the bridge since they have to make that gigantic U-turn around North Island to get in or out. So if something did go wrong they'd be at a lower speed and would have tug assistance to help navigate.
An interesting thing no one seems to be talking about, is that the SD bay bridge's center blue section is designed to float, so that in case of an attack, the US Navy can just Ram it out of the way.
Correct!! If, God forbid, the harbor were ever attacked, the center section is blown and moved away. There's also plans to blow the area that's thinnest of the strand for travel. PLUS we have several LCAC up north just south of Pendleton for transportation of troups, gear, and equipment for fast transport to the well decks of the (LSD or LHD) off the coast. Sorry, I get them confused.
@@brettgoldsmith9971 Not really the case... en.wikipedia.org/wiki/San_Diego%E2%80%93Coronado_Bridge#Description Urban legend A decades-old local urban legend claims the center span of the bridge was engineered to float in the event of collapse, allowing Naval ships to push the debris and clear the bay. The myth may have developed as a result of the hollow box design of the 1,880-foot center span, combined with the low-profile barges that made it appear to float on its own during construction. However, Caltrans and the bridge's principal architect, Robert Mosher, maintain that the legend is false.[34
The bay bridges in San Francisco Bay all have protective 'dolphins' or concrete fenders constructed around the supporting piers to protect the piers from being struck. The Key bridge had no such protection.
Those fenders are meant to redirect a glancing blow from a larger ship and stay intact during a large earthquake. No bridge is designed to have a skyscraper run into it.
@@bryfunkenstein the F. S, Key Bridgeis about the same size as most of the bridges in the Bay. The much bigger difference is how tight the dredged shipping channels under the bridges in the Bay are. A ship that came so close to hitting one of the bridge supports in San Francisco would be more likely to run aground before it hit the pylons with enough force to knock them over.
So does Baltimore, the difference is that in SF Bay the shipping channels are so narrow that the ships can't get up to full speed while in the Bay, so they needs tugs at all times. Once the ship is moving at full speed, the tugs are useless. So once the Dali had been turned around and pointed down the shipping channel to go under the Key bridge, the tugs disconnected because only something truly catastrophic like a full-ship power outage with the rudder then turning hard starboard would prevent that ship from going anywhere except directly under the bridge.
Not only does San Diego use tugs we don't have those ships here The port of San Diego won't allow those ships to come our port and our city are weake as heck and fear maritime they fear world trade they fear making real money
These two young engineers only repeated the requirements, like slogans. In 1:21 photo the Key bridge has pier foundations cross way to the shipping lanes where the large ship bow can easily reach the columns of the bridge then damage it. In photo 0: 54 it shows the Coronado bridge pier foundation has extended long buttress against the shipping lanes, thus protect the columns from any ship's bow to impact. The Coronado bridge was built to prevent ship collisions. 🤔🤨😃😎

Planners know full well a ship could go out of control and hit the support tower base. The engineers cannot design for this if it is not a requirement. In other words, it has to be agreed upon and paid for. The golden gate bridge, for example, does have such a protective structure at the base of the south tower that is standing in open water. When the Golden Gate bridge was proposed, the US Navy was VERY concerned about the bridge collapsing and blocking access to San Francisco Bay. Not all bridges then or now have such ship collision protections required. Add to that the super large container ships are far larger than those of 50 years ago. All bridges should be evaluated for the worst collision.
The Golden Gate and Coronado Bay bridges are constantly under monitor and care. The US Navy and other feds have plans needed to handle should an event ever occur such as earthquakes or other.
It doesn't matter what stupid bridge you have there is no bridge in the world designed to survive a collision with a cargo ship. It's physics the bridges were designed to handle wind and large loads of traffic but not something dramatically heavy hitting one of the most critical parts of the bridge.
These container ships weigh on the order of 200,000+ tons (400,000,000 lbs) at 8 knots that's a LOT OF FORCE, like 800 lbs of TNT force! There is very little that could withstand that.
But in San Diego we don't have those you have to go up to Los Angeles our port is too weak to have these kind of ships our port is too useless to have these ships our port is non-compliant to have these ships it's weak we have a weak port commission that caters to hotels not world trade That's why you'll never see San Diego as a real port
What are you talking about San Diego isn't even on a scale to Baltimore when it comes to massive car dealerships San Diego is so weak and pathetic it's not a big port Don't worry for the size of its bay it's a very very small port with very little industry in it so don't worry San Diego will never ever be on a scale of Baltimore or Los Angeles or New York or San Francisco or Seattle or Houston or Miami San Diego is a little dinky place with little maritime
My question is if they were able to stop the traffic before the ship hitting the bridge then why were the bridge worker not notified about the potential diasaster coming their way?
If demolition crews didn't care about safely knocking down a massive million ton load-bearing structure or cleaning up the aftermath and could safely do so by driving a skyscraper into it, they probably would. But since they can't and don't want to do any of those things, they take the time and do it safely instead.
A cargo ship, 1,000ft. long, can weigh 100,000 tons or more, traveling at just few knots of speed it can take a ship a mile or so to come to a complete stop, reversing engines would help, but it's still going to travel quite a ways, that's one heck of a force of impact, if it hits a main support beam, it's all over.
@@jwC-zk3vd Excuse me, you're slightly incorrect: a 1000 foot ship carries over 100,000 tons of _cargo._ The ship itself then weighs several tens of thousands of additional tons. Assuming a full load, the Dali probably weighed close to 200,000 tons when it left port. That would be roughly 2/3rds the weight of the whole Empire State Building in NYC running into the bridge.
When the World Trade Center was designed in the late 1960s, the architects took aircraft strikes into account for safety. Unfortunately, the heaviest jet aircraft of that time was the Boeing 707.
You cant antiseptics a ship hitting the bridge?? If a shippi can sail directly into it....design for that....or design to put barriers in to prevent it
They absolutely anticipated a ship hitting the bridge. There were tons of reinforced pillars holding the deck up. A nearly 1000 foot gap underneath it gave plenty of room so that ships which momentarily lost control could safely manuever themselves to avoid the pylons so long as they still had rudder. The ship lost rudder at exactly the worst possible moment, while at full speed charging for open water just on the other side of the bridge. It was a 1 in a million chance that shouldn't have been able to happen. A butterfly wing causing a hurricane. _NOTHING_ can withstand a fully loaded cargo ship hitting it at full speed. The bridge was essentially hit full-on by a moving skyscraper. And not just any moving skyscraper - a ship that weighed more than 3 times the weight of the heaviest ship in the world back when the bridge was opened in the 1970s.
There is no comparison, Coronado ,Bridge is Top 5 bridge through out the Entire World .. I kmow i painted the bridge. Gor many years a 25 :cent tow charge was collected coming onto the Coronado Island.m . That 25 cents over a period of many years fundedd every year repairs. No ship or any boat can say this..
As far as bumpers around the bridge supports, if you have a big enough boat, they'll just be plowed over with the bridge hit next. Maybe if these bumpers were 500+ feet in diameter, they may work, but then they're blocking the area where ships can pass through.
@@Adeon55 So disgusting that you're correct. American taxpayers will have to pay for it since Dementia Joe said "the federal government" will pay for everything. Since the federal government doesn't actually create or produce anything, the only money they have is what they steal from American taxpayers. Just think about what we could have done with the 200 Billion American taxpayer dollars that these as*holes sent to a totally corrupt government in Ukraine. We could have built ALL of POTUS Trump's border wall for 1/10 that amount which would have stopped the current invasion by millions of illegal criminal aliens. Then we could have fed, clothed and housed our homeless Veterans, etc, etc, etc.
There was nothing wrong withe the general design of the Key bridge the problem was protecting the bridge from being hit as any bridge that is hit from a ship is most likely to fail beam bridge is not suitable for the port of Baltimore as the shipping handles 20 times the cargo as San Diego (after all San Diego is just a comfortable place for the rich to live) and the ship had been in the channel as all large ships passing under a bridge the ship didn’t suddenly decide to travel outside of the channel it lost power. So it looks as if it wasn’t possible to build a protective barrier a tug should have been required to escort the ship in case of a problem
The only time I drove over the Coronado bridge was in Drivers Training everyday for the duration of the class in high school. Never had to drive over it again. LedHed Pb 207.20 🎶 🎸 🎹
I crossed this bridge from 1984-2004 while serving in military. It still makes me nervous sometimes. When I heard about the bridge incident on CNN my first thought was the Coronado bridge. Nice views though.
As a Registered P.E. in both Mechanical and Structural engineering, and with over 30 years of experience, I can state with confidence that they're obviously diversity hires. Both of them are idiots.
The Baltimore bridge is named after the man that wrote the Star Spangled Banner. It was a Terrorist Act. So no, absolutely NOT was the Baltimore bridge just a bridge to be compared to others.

The same people who built it in the 1970s: the government, with tax dollars.
Joe Biden: "It's my intention that the federal government will pay for the entire cost of reconstructing that bridge."
So, we all are.
@@Adeon55 So disgusting that you're correct. American taxpayers will have to pay for it since Dementia Joe said "the federal government" will pay for everything. Since the federal government doesn't actually create or produce anything, the only money they have is what they steal from American taxpayers. Just think about what we could have done with the 200 Billion American taxpayer dollars that these as*holes sent to a totally corrupt government in Ukraine. We could have built ALL of POTUS Trump's border wall for 1/10 that amount which would have stopped the current invasion by millions of illegal criminal aliens. Then we could have fed, clothed and housed our homeless Veterans, etc, etc, etc.
That bridge collapsed like house of cards.
There was nothing wrong withe the general design of the Key bridge the problem was protecting the bridge from being hit as any bridge that is hit from a ship is most likely to fail beam bridge is not suitable for the port of Baltimore as the shipping handles 20 times the cargo as San Diego (after all San Diego is just a comfortable place for the rich to live) and the ship had been in the channel as all large ships passing under a bridge the ship didn’t suddenly decide to travel outside of the channel it lost power. So it looks as if it wasn’t possible to build a protective barrier a tug should have been required to escort the ship in case of a problem
Silver strand 😅 road works too but we love Coronado bridge
My fear of crossing large bridge has increased!
At the moment the Coronado Bridge is shut down in all directions
Was that bridge demo'd?
Thank goodness the Coronado Bridge was built 60 years ago and not under California's current government.
Ah, the good old days when we exported and didn’t import EVERYTHING. All the way back in the 70s …
One speed boat away
Thank you you’re beste always
'No one can anticipate such things happening..' Really?!
Yeah no one can anticipate such things happening. So I wonder why many bridges around the country have been upgraded with pile protection?
Betsy Ross Bridge has barriers to protect the uprights, most don't
Makes me wonder if underground tunnels are better
The Coronado Bridge is Nothing like the Baltamore Bridge,
Buttigieg should be in prison.
Now Everybody wanna know if their bridge is safe
Put a sky hook on it
How does it compare!! It’s still standing ffs 😂
It still exists
The only time I drove over the Coronado bridge was in Drivers Training everyday for the duration of the class in high school. Never had to drive over it again.

They’ll use this as a poor infrastructure excuse.
I crossed this bridge from 1984-2004 while serving in military. It still makes me nervous sometimes. When I heard about the bridge incident on CNN my first thought was the Coronado bridge. Nice views though.
All you need is a Ukrainian captain and a cargo ship to find out.
Put back the Light Houses
The captain of the ship must be a wreck right now
No, he is sleeping fine. “electrical interference” kept him and his crew out of prison.
BABYLON IS FALLING
Looks modular enough to maybe not all fall down when one section breaks.
Well I guess it depends how many military bases are around it.
What has happened to our country? We don't pay attention to our bridges until one collapses and people are killed?
Its called an accident.
Nothing else.
@HossEehoss Yes, it was as far as know it was an accident? That doesn't excuse incompetence
@@williamdavis9943
"what has happened to our country?"
That's a tad bit extreme considering that was a huge ship that made contact.
@HossEehoss It takes extreme measures to prevent such a tragedy. There should be a bridge shield wall built to prevent a collision with the bridge.
That goes for everything, not just bridges.
So blame the bridge not the ship. It reminds me of another pattern going around. 🧐
Just waiting for that Longbeachgriffy video 😂
Tugboat?
Are any of the "experts" a DEI hire?
As a Registered P.E. in both Mechanical and Structural engineering, and with over 30 years of experience, I can state with confidence that they're obviously diversity hires. Both of them are idiots.
The issue is not the bridge. The issue is why the boat hit the bridge. Ffs
Well most bridges have safety blocks to stop this. there was none. This is what happens with a DIE transportation secretary who's only focus is DIE
Cargo ships cant even fit in the channel. The water is way too shallow. The ship would ground itself before getting to the bridge
@gonefishing11 these super cargo ships like the one in the video you cant even compare.
The Baltimore bridge is named after the man that wrote the Star Spangled Banner.
It was a Terrorist Act.
So no, absolutely NOT was the Baltimore bridge just a bridge to be compared to others.
Ever see the size of these container ships, they are obscene and immoral
Coronation vs. Marry Land
Not even close
course is going to fall if it gets crashed into what did they expect. Don't crash into it is the best option
They are of the same quality.
Yeah don’t drive a cargo ship into it
I was stationed in SD.... could feel the blood draining out of my face every time I went across that damn bridge.....😱
That bridge came down like a flimsy house of cards.
