I-5 bridge collapse: reflecting on our crumbling infrastructure
The I-5 bridge has collapsed in Washington and there are “vehicles and people [in] the water.” No word yet on casualties, and here’s hoping there are none.
Meanwhile, as bad as I hate to say we told you so, we told you so. Various S&R writers have written about various infrastructure issues in the past, and as the story in Washington unfolds, perhaps there’s some value in pointing our readers to some of the more relevant links.
Dr. Denny from July 2010: Drive with care over those 151,394 obsolete, unsafe bridges
Dr. Denny from August 2010: The nation’s 120,000 dams: Much more inspection, repair needed
Wufnik from last November, post-Sandy: Getting ready for the next disaster
If you’re in the mood read more, sift through our Infrastructure category.

Human error, not crumbling infrastructure. Over-sized load clipped the top of the bridge.
I’m wrestling with this. Yeah, I get that if you hit something hard enough it’s going to fall down. But have you ever heard of a truck knocking down a sound bridge before? It may have happened, but I’m not aware of it. I’m going to be interested in whether or not further investigation finds structural issues. Maybe it won’t. But a bridge that old in a nation where we have severe infrastructure issues – you can understand my curiosity.
The last three Bridge issues, well, only three since the referenced articles, were all human error related. One had a ship driven into it, one was repaired badly then failed a short time after, and in this case you had an oversize load hit it at 55+mph. It wasn’t just a truck, there was plenty of mass on that oversize load and if you hit a truss bridge at a pivotal point it’s like a house of cards.
And I sure do understand. There could well have been structural issues with the bridge preceding the event, but that will be in the records. Whilst repairs and maintenance are being carried out slowly, you can be sure every bridge has been checked by engineers for those faults. Would be interesting to see what comes out in the wash.
Just glad no one was seriously hurt.
No one hurt – that’s the best news in all of this.
And a ship hitting a bridge, yeah, that one I get. As I say, I’m not arguing that it isn’t possible.
But do give that link about the bridges a look, if you haven’t already. In an age of deregulation and a refusal to fund infrastructure, we’re probably well advised to be extra diligent about what we’re being told. Being a bridge inspector has to be a terrible job because there’s not much way of correcting what you know is wrong.
As I recall, btw, one of the bridges on the danger list is here in Denver. You know the Evans bridge across Santa Fe? Yep. I get nervous every time I go under that thing…..
You know me, mate, I checked out every link!
IF you’re right, I must be thinking of the wrong bridge. Next time I’m down that way I’ll double check and I’ll also see if I can find the list I was looking at.
This isn’t what I was looking for, but yow. http://www.forbes.com/pictures/efee45gkfd/denver-aurora-co/
It looks like you’re right, Frank. I can’t find that bridge on any structurally deficient lists. There are a number of such bridges about town, but evidently not that one. So now I’m wondering which one I’m confusing it with.
I found a kml file with all the deficient bridges in town here.
In the Art of War Sun says that if you try to defend all places all will be weak. This is what’s happened with the US Government. You can’t be everything to all people and have it all work.
So Sun Tzu believed a stable infrastructure is a sign of weakness?
No, one of strength.
Okay, I have no idea what point you’re trying to make.
The Government needs to be more decerning in what it try’s to fix. It can’t fix everything and it shouldn’t try. Taxes will always be a limited resource and infrastructure should be a priority above many other things the Govt spends money on.
Like, perhaps, spending as much on military as the rest of the world combined?
I’d be good with that.
Me to, and I’m prior service SF. And I don’t see any wisdom in spending billions on new roads when bridges are failing and hundreds of others have been noted as in filing condition. Same for tons of programs that serve narrow interest.
