Why The Mississippi River Bridge Collapsed
HTML-код
- Опубликовано: 12 апр 2024
- The I-35W Mississippi River Bridge collapse, a tragic event in American infrastructure history, occurred on August 1, 2007, in Minneapolis, Minnesota. The bridge, a vital artery connecting the northern and southern parts of the city, failed during evening rush hour, sending vehicles and their occupants plummeting into the river below. Thirteen people lost their lives, with many more injured. The collapse brought attention to the state of aging infrastructure across the United States, prompting discussions on the importance of regular maintenance and investment in updating bridges and roads. Investigations revealed design flaws and structural deficiencies in the bridge, highlighting the need for stringent inspection protocols and infrastructure renewal efforts nationwide. The disaster spurred significant changes in infrastructure policy and funding, emphasizing the imperative of ensuring public safety and the resilience of critical transportation networks.

Clarification ⚠️ August 1, 2007 was a Wednesday 0:06
FYI, August 1st, 2007 was a Wednesday, not Saturday. It was during rush hour, when the tragedy occurred.
Yes, big mistake in this video. I had just left the twin cities and was delivering a load of tires to the Sears store in Duluth, MN when the news broke that the bridge had collapsed. I did the same run every week so I know for a fact it was on a Wednesday.
Yes RUSH HOUR on a weekday crucial detail!!! Our cell phones wouldn't work because the networks were overloaded.
was just thinking that. pretty sure it was a weekday. my father had been on the bridge 5 minutes before it collapsed. realistically, he was probably one of that last people across the bridge
Friend called family to say that he just got off the bridge.
Thank you very much for this important clarification 🙏
Not only did the state have to rapidly replace that bridge, they also had to replace an identical bridge in St. Cloud on MN 23, crossing the Mississippi River. The same undersized gusset plates and corrosion were found. The bridge in St. Cloud is also a major artery for the region. That bridge collapse was tragic, but at least the state didn't let another collapse just over an hour's drive north.
As a University of Minnesota student, I would bicycle across the bridge before it was opened to work at the Pillsbury R&D lab on University Avenue.
In the early 70's I became a journeyman ironworker, Local 512, Mpls.-St. Paul. We once worked welding the deck of the Hennepin Avenue bridge (one of the oldest and main bridges downtown).
It was built on giant limestone blocks, about 14' cubes. The top was all shale broken pieces. Guy pushed a rebar down into the shale and the 8' rod totally sank !!
Called city engineers and bridge was IMMEDIATELY shut down, about 3 PM on a summer Friday.
I crossed that bridge 6 times that week, the construction made it so you had to sit on it for long periods of time. I had 3 babies in the back seat! I still can't believe that we got so lucky not to be involved in the collapse
I live in Winnipeg, about 450 miles from Minneapolis. I remember police divers taking leave, throwing their tanks in the car, and heading south.
Seems to me it was a Wednesday evening rush hour when that bridged collasped, I should remember, I damn near died that day.
My parents called me at 5 PM to ask if I was on the bridge. I was confused because my evening commute didn't go anywhere NEAR the bridge.
Thank God You made it That's good Have blessed evening
Just to be clear… the weight of the construction materials 578,000 lbs that was spread over the bridge is only the equivalent of just over 7 standard loaded semi trucks! US highway standards allow each truck to weigh 80,000 lbs. Only half the lanes on the bridge were open so this load was taking the place of what could have been 4 lanes full of traffic which could have easily included 8 or more trucks which would have been much greater. Additionally, Metro buses could weight up to 48,000 lbs loaded. The bridge actually had less weight on it than it usually carried and most of the construction load was dead load as opposed to truck traffic which would have been a live load. The only reason this diversionary cause persists is to deflect from putting 100% of the blame where it belongs - squarely on MNDoT and the MN state bureaucrats who repeatedly ignored the safety reports and state and local politicians who delayed funding a replacement in favor of new Light Rail construction.

I have a cousin that went to the University of Minnesota campus in the Cities, at the time. He had classes that day, but he ended up being sick. If he had went, he would've drove on 35W
I remember this day well my teacher's husband most likely would have been on the bridge when it went down. However his boss kept him late that day. I was nervous going over older Bridges after it happened.
Thank you "It's History" for your dedication to history!
Thank you too!
RIP to the lives lost.......
Must say the new bridge looks so much better, hope is has a long life.

I've always been afraid of crossing bridges, but people keep trying to convince me that they won't collapse because they're built with redundancy. Apparently, not so. If that bridge in Baltimore is anything to go by, building bridges with redundancy is not the norm. Or at least, it wasn't when most of our bridges were built.
A friend used to travel that bridge alot,would tell us about the bridge would shake ,and move when setting in heavy traffic.
This was one of those moments in time where you forever remember exactly where you were and what you were doing the moment you heard news of the disaster...
The people trying to stop a new bridge for I-75/71 from being built over the Ohio River in Cincinnati need to watch this. The Brent Spence has been functionally obsolete for 30 years.
They don't care. Same type that cost taxpayers 100s of millions while endangering their lives fighting the replacement to the Herbert C Bonnet bridge that was decades past due and had already partially collapsed from a barge.
This bridge collapse was the catalyst to all bridge replacements across the nation. No more kicking the can down the road.
Really love your channel and the content. Lots of great info and stories. Thank you!
Thanks for watching!
I remember this well. I had completed a bunch of bridge inspections and later submitted the annual report the day before the Minneapolis bridge collapsed. I thought I was done, but we had to revisit all the bridge information and ratings, just to be sure we didn't miss anything that could have also become catastrophic.
Not an Engineer here even if I was a Combat Engineer once Upon a Time. I was just one of the guys building and doing rehabs on bridges for a living. Seemed most of the bridges suffered from one particular problem. Lack of proper drainage. After they are built that isn't maintained. Scuppers and piping plugged forever, expansion joints draining on top of what they shouldn't be. The freeze thaw wrecked havoc in those areas. Steel would rust, concrete erode you know all about it. Some designs drain them differently these days. Don't have wide open expansion joints draining on the piers either.
Reminds me of the Skyway collapsing back in the 1990's. Except that was caused by a perfect storm of conditions, it was a particularly foggy morning, a cargo ship had very poor visibility and thus collided with one of the bridge's supports columns, which subsequently caused the bridge to collapse... The current Skyway was built with this hazard in mind.
Went over the new bridge today
So they rushed and were careless to make the first one. And they rushed to build this one. I guess people never learn.
I’m looking forward to this channel’s video on the Francis Scott Key bridge! It probably won’t be made until the new bridge is built of course.
He could always do the building of the bridge.
Probably won't be done until at least the NTSB report and subsequent lawsuits.
@classic.cameras yess! Including any previous studies on the bridge ending it there fornow
There were three other identical bridges that were closed and replaced not too long after this. The most identical being the Hwy 23 bridge over the Mississippi River in St. Cloud, MN.
Winona bridge also was replaced around the same time
@@commentor3485 Winona bridge is still there. They built a new bridge next to it and now use both of them.
@@randyjohnson2794 they did a good job with the new one :)
cant wait for the episode on surfside condos
I'm from Ohio, but was living in south Florida at the time and had worked on a nearby hotel a few years before the collapse. Someone ignored the inspection reports showing how the concrete deck and columns had water saturation from the planters, which caused rusty rebar. Unfortunately negligence seems to be a common theme when a structure fails. Why even do inspections if they're just going to be dismissed?
Yay some Minneapolis love! Woiuld love to see more Minneapolis things!
It was a Wednesday.
I was on the hennipen bridge on my bicycle. After work.
I didn't work weekends.
@@diegomontoya796 It was my commute route, and that day traffic was backed up at the tunnel, so I diverted to Broadway Ave. - which was nothing new. I got home and boss called on the Nextel, asking, "Are you home?" I said yes and he replied, "turn on your TV."
Thanks for the video!
Why is the Golden Gate Bridge still standing after all these years?? I was a small child when I went over on this bridge. Now in my late seventies I’ve seen too many tragic stories of bridges failing. Some contractors just don’t care! The “it won’t happen to me” thinking?
Love the content. I always look forward for a new uploaded video!! Great stuff! I hope you are working on a future video consisting of the now semi abandoned Letchworth Village in Rockland County, New York.
I worked less than a mile away from there when it happened. I heard a loud noise, but thought it was the trains right behind my office. When I left the office and crossed over 35W, I noticed there were no cars heading North, and only saw emergency vehicles heading toward the bridge. I turned on the radio and heard what happened. Amazing that there wasn’t more injuries given how many cars go over that bridge during rush hour.
Thank you Ryan for sharing yet another interesting topic! I truly appreciate all that you bring us! Your dedication is very well noticed here!
Got bless! ~ Scott 💙🙏🏼
I appreciate that!
another great vid !!
I live close to the Mississippi River Delta. I would hate to see something like that happen down here. If people managed to survive the fall, and get out of car before it sunk. Swimming in that river is super dangerous.
And then there was the Francis Scott Key Bridge collapse in Baltimore on March 26, 2024, that happened when a pier was strike by a freighter.
I got a call from my Mom's cousin in Nashville about the bridge. My youngest sister passed over it about 10 min before it went down. She didnt hear about it until later on Social Media.
It was social media in 07?
@@m.e.5482 Yes.
Prayers. For. The. Family
Absolutely avoidable. People who are supposed to have people best interest in mind, failed here. Idk I don’t feel great about them rushing the construction of another bridge.
Why don’t you do a segment on the Francis Scott Key bridge 🌁 😮 21:35
We're still learning about the FSK Bridge collapse.
My daughter was on a Church Choir trip in MN. They had been on the bridge that morning and under it on a boat tour prior to that day. It changed their route home to Memphis.
Great job Brian! Now how about a video about the raising of the RR rights-of-way in city of Chicago which began in (I think) the late 19th century and continued for about 20 years until nearly all at grade RR crossings were eliminated in the city? Or how about a video on the reversal of the Chicago River with the Sanitary & Ship Canal, one of the greatest engineering feats of the 20th century? I know you can do it, kid!
Its surreal to see a major piece of metal bent like that.
Please review Silver Bridge story, will be on final exam.
This didn't happen on Saturday...I was on it 2 hours before it went down 😂
Yep it was a workday I remember that...
Maintenance ever done on that bridge by the NTSB. All bridges should be inspected every two yrs. X-Ray joints, including decks, Laser all beams for any structural deflection, X-ray bearing joint to concrete, X-ray concrete pillars every two yrs. If passed inspection then document all records. primed and painted.
Poor Minneapolis seems cursed.
The video would be improved if the background music was removed.
it was a weekday though Wednesday to be exact
Given the immense amount of research that had to go into this video, I'm guessing it's a coincidence that it came out just after the latest bridge collapse. Good work in any case.
Alas, he couldn't even get the day of the week right.
The following inspection of all bridges found that sea creatures that once threatened wooden ships adapted to fresh water and were eating the pylons. The bridge was deemed to be in eminent threat of collapse. Being a primary route to 95 north of NYC, the death toll and resulting repercussions of the loss of that route would be catastrophic. The new bridge took about 5 years from start to open. But, then it is over 3 miles long and like 4 times as high as the 35W bridge.
Good video as always but it was during wednesday rush hour, not Saturday.
This was the Twins game before which there was going to be the ceremonial ground-breaking for the stadium that was to become Target Field at the beginning of the 2010 season.
The Ohio bridge collapse was the Silver Bridge, not the Silver City Bridge.
Wow sorry for those lost their life's at first thought they were talking new Orleans.
How about the bridges in downtown Milwaukee, Wisconsin all being built at a slant.
The government needs to put more emphasis on inter structure of Bridges, highways and overpasses periodically inspected for inter structure corrosion and support on a regular basis to catch any deficiencies in each structure because it’s an necessity
That bridge was garbage the day it opened.
@@thomasdahlquist7119 really
My cousins wife went over that bridge, before it collapsed.
Is that why it collapsed
@@Mcmerc01 C'mon man! 😅
I had driven over that bridge the day before it collapsed.
why are you speaking in metric terms ?
For the same reason he called the truck a lorry... He ain't from 'round here...
Amen
14:40 "305 m of deck truss collapsed, 140 m of main span fell into Mississippi, which was flowing ... 4.5 m below ... " 15 feet ?? Or is it 45 m = 147 feet ?
🙏🏾
Inused to look up the ratings on bridges i would travel....because of the ratings i stopped traveling. I have been to about 40-43 states so I just stay in a relative small area of Missouri. A new bridge is in the process of being built... I will travel on it soon. :)
I. Like. This
If we had more public transportation and light rail systems like other countries, we'd probably have less of these issues. Although, the way politicians missappropriate funds, we'd just have other issues ...
“Economic development for the city”. Not really… look at how all the space was used prior to 35W and look at it after. 35W blighted the area
Railroad freight wagons????? Where are you from?
all our bridges are not in good Shape at all
I was booked into the Hennepin County jail that day for beating on my old lady and saw the bridge collapse on the news.
that is what Happens when you Park 400 tons on the Bridge or the weight of 2 Diesel Locomotives. road bridges were never design for trains
Happy BB62 is in better shape.
I am like number 916
See how they slid right past the demolition of some city blocks. What city blocks exactly?😂
I had just got off work a couple hrs before this happened my girlfriend woke me up kissing me saying I'm glad u didn't work late the bridge collapsed.
That Highway goes out to where poor and colored people live
Why don't we hear of 100 year old railroad bridges collapsing? Why is it just highway bridges?
Railroad bridges typically aren't salted the way road bridges are. Especially bridges as that's where ice forms first.
Road salt. Ocean salt.
It destroys cars, it absolutely destroys bridges.
Wish I could easily buy cars from southern climates!
@@volvo09 Although cars in the south don't experience road salt like those in the north, they do experience a lot of sun damage. I'm from Ohio, but had lived in Florida for a while. I'd never in my life seen so many faded red, blue and green cars. Also the interior dashboards and paneling tended to crack and crumble. That's partly why most vehicles have tinted windows in the south.
@@Josh-yr7gd The SW will trash the synthetic components as well. Phoenix is really hard on fan belts, coolant lines and batteries. The hot, dry air is incredibly hard on cars.
Because freight is expensive so they repair the bridges.
Des ingénieurs mickey mouse.
Because of Joey, the puppet and the puppeteers decided to spend the money on other things, but called it build back better
The colonial days are over! Modernize like in the Western States and Singapore!
Collapse caused by gravity. Video over. 😅
First?! 35 seconds thought it said 35 min
Me too! I just freaked out!
800 views 😂😂
That's because it's Minneapolis time 😂
Congratulations on your victory! Here's your participation trophy!!
🏆😂
I seem to remember reference to erosion caused by acid of pigeon droppings on the metal contributing to the weakness of the bridge.....
