Posted on 08/01/2007 4:28:27 PM PDT by ButThreeLeftsDo
Just turned on the news. 35W bridge collapsed in the Mississippi River. Cars, trucks, semis.....
Fires burning, tanker trucks, at least one school bus, more than ten cars......
Just now breaking.......
You will also see stuff getting airborne when a concrete road deck shatters because the supports underneath it have given way.
We are a country at war, they admit there are currently Al Quaeda cells operating in the U.S., so what are they doing, watching American Idol and going to baseball games? Oh I'm sorry that's what we're doing.
Don’t know about last week, but this one was closed down to one lane tonight.
I pray this isn’t terror as I jusy posted a couple of hours ago, how it felt like the summer before 9/11.
There were apparently 30 construction workers on the deck when this happened. IT would have been really tough to place and ignit shape charges.
i don’t remember.. was the bridge in the movie in the same area? same bridge??
There is an engineer on this thread right now. If you see this post would it be unusual for object to blow up when this bridge collapsed??
Oh man BTLD! Just came in from a peaceful evening outdoors.
Prayers all the way around. I used to cross that bridge a couple of times a day. Can’t imagine being on there when it colapsed.
Do you have a link?
I hope it was only infrastructure, but beware of other “incidents” during the next few hours to be sure....
Please tell me you are being sarcastic. Please.
I’m new to this thread. I just tuned into MSNBC (can’t stant Shep) and they said the construction was resurfacing. Were they doing major construction on the road, or was it just resurfacing? Thanks for any info.
If we see something, Homeland Security says something before we can. Wonder the Chertoff Feeling Meter is registering.
I’m pretty sure it’s the same one. When you’re on this one can you see the cedar ave bridge? I don’t remember being able to see it (in fact never knew it was there).
Oddly enough, this was the type of structural failure that ultimately caused the collapse of one of the two WTC towers on 9/11.
Years ago it was reported that the Chinese were mislabeling lower quality steel as higher grades so it would sell better. They didn’t care what might be effected by this. I wouldn’t doubt when the investigation is complete that they used substandard rivets or other steel in that work on the girders last week.
The Bay Bridge didn't collapse in '89, only a single section on the top level came partially loose.
A section of elevated freeway in Oakland, however, did collapse.
I was there...(in the Bay Area)
Released on The Blotter an hour ago:
A new al Qaeda propaganda ad, headlined “Wait for the Big Surprise” and featuring a digitally altered photograph of President George Bush and Pakistan’s President Pervez Musharraf standing in front of a burning White House, was posted on the Internet today.
The brief clip from al Qaeda’s “as Sahab” propaganda arm juxtaposes the doctored photo of Bush and Musharraf along with previously seen images of al Qaeda’s top leadership — Osama bin Laden, Ayman al Zawahri and Adam Gadahn — as well as a photo of an SUV in a motorcade.
There is no additional information provided in the ad, and it closes with the words, “Soon — God willing,” written across the screen and repeated several times.
Easy... Step away from the keyboard... And the crack pipe...
I agree, but it looks like the middle one has disappeared entirely.
Compare it to its twin span running parallel.
Even if the terrorists didn't do it, they'll be tripping all over each other to claim credit for it. Getting credit for something you had to spend no time, money or effort on suits them even better.
You know, I was wondering about those trucks sitting on the ice or if they let them pass carefully, stopping trucks that were not on the ice. They made a very big point in the beginning about trucks not being able to sit on the ice for any length of time or it could cause the ice to collapse.
Thunderstorms moving in
Just south of there,
The bridge that collapsed apparently was not constructed with piers like the one next to it. Nearly a suspension bridge with one large span.
eyewitness on the news said the river span failed first, pulled down the rest
“A steel member in a structure is typically designed to accommodate 40% more than its anticipated “dead” load and 70% more than its anticipated “live” load”
That may be what you require as an engineer, but as a steel detailer, I always design each end connections for 75% of the total uniform load. we always go further than what the engineer calls for. You are right this probably wasn’t terrorism, I just didn’t want people to think that traffic isn’t taken into consideration when designing a bridge. Or that crappy material would be used without many levels of checking. The engineers of this country and the AISC using ASD are the best in the world. I just don’t want people loosing faith in engineers.
Is it just me or do the bus and burning truck seem to be at a sharper angle every time they show them?
They are doing a good job with this disaster yes, but they keep wanting a body count ---- kinda like the body counter they had going with the soldiers in Iraq awhile back.
Normally I don't watch channel 5 and let's see how many more times they can ask how many deaths.
The good news is that there are two or three hospitals within walking distance of this disaster. The Red Cross has a building that actually is within direct view of the disaster.
Shep said about 20 mins ago or more that Homeland Security said they believe it was NOT terror related.
The connection points to the pylons look awfully small. (See the lower right corner.)
A jackhammer in the wrong place at the wrong time *can* bring down a structure. Resonance *can* destroy a structure - see the Tacoma Narrows disaster.
Witness on Fox says that it wasn’t an explosion that he heard/saw, he saw the long span bend and shatter in the center and give way - the actual support pylons were not involved.
I live near Pittsburgh. It has more bridges across the three rivers there than anywhere else in the world. They’ve never collapsed and many are probably a lot older. They are in a cold, snowy area with a lot of freeze-thaw cycles in the winter. This just looks funny to me.
I am shocked the Twins are playing baseball during this.
Is there a strong curent there? Looks a little like whitewater, that can’t be helpful.
I’ve been on that bridge recently.
It was surface construction. I’m not aware of any structural work going on.
Ordinary people doing extra-ordinary things in order to save and help people. Right now.
Jeez- all these conspiracy theorists. Get a grip... get a life, all of you. You’re making FR a laughing stock to the rest of the world
The cynic in me, remembers all the people in Oklahoma City who saw a "middle-eastern" looking man running from the Alfred P. Murrah building too, but that angle was soon discarded. :o(
That article was from 2005.
Stop spreading it.
“sorry, dead weight is much different than live weight. the bridge would have been designed to hold that much dead weight. ROP and if Im wrong...”
Sure it was. Forty years ago. I said weight plus accumulated metal fatigue and corrosion.
Thanks, I looked it up too. So they have about an hour of light left. What they call civil twilight ends at 9:14.
Not only that, they would need to know where and how to place them which isn’t as easy as it sounds. If terrorists had the means and ability to do this, they would have been able to take down a far more spectacular target.
Me too - where were you??
Lousy politics, but great health care.
OK, witness is clarifying their statement - witness is describing items in freefall as the bridge collapsed, not explosions.
“Highway 35W North was closed for resurfacing at the time and it was quite hot here today so, it’s entirely likely that those were factors and not terrorism.”
Does steel melt at 90 degrees?
This is the lady in the red car.
If you mean "explode," I'd say that's unusual (except for the fact that you have one or more fuel trucks involved here).
If you mean "lifted vertically in a sudden manner," I'd say it would not be all that unusual. It looks like one or more sections toppled instead of just collapsing, so the rotation of the slab (toppling motion) could easily lift cars, people, etc. up in the air.
I think it was decking rehab, taking the old concrete out.
