  • Narrows Bridge II: Electric Bugaloo?

    From the sounds of the article, this one may just fall the fark over. Probably won't even get a show out of it.
  • Sounds like this one will sink more than it will fall over. Does that place freeze? Poor steel and poor concrete make for a great place for water to hide. If it freezes then it will pop off big chunks of concrete and weaken the whole structure.

    I move for news to go back to having riveting background music in it.

    it's a floating bridge, if the allegations are true most likely you would have a pontoon breach and start taking on water. probably not severe enough to cause structural failure - but it would need immediate attention - pump out the pontoon (i think they have pumps with auto triggers) and patching.

    It'll burn down, fall over, and then sink into the swamp.

    But the third one will stay up!
  • Look, pal, we can't compete in the marketplace with Chinese competitors, so some things gotta slide.
  • But don't worry, the deep bore tunnel through three types of rock, running right next to Puget Sound and over a known fault line will totally be safe.

    /and on time
    /hardly any cost overruns too

    IIRC Tacoma Narrows was kind of a freak thing.

    Othmar Ammann, a leading bridge designer and member of the Federal Works Agency Commission investigating the collapse of the Tacoma Narrows Bridge, wrote:

    The Tacoma Narrows bridge failure has given us invaluable information...It has shown [that] every new structure [that] projects into new fields of magnitude involves new problems for the solution of which neither theory nor practical experience furnish an adequate guide. It is then that we must rely largely on judgement and if, as a result, errors, or failures occur, we must accept them as a price for human progress.[26]

    This one sounds like they just said "f--k it" to things we've learned from freaking failures. Very different. Sigh.

    I live in a terribly dry state, but I have relatives in Seattle and Port Angeles, and I love the area. So just curious, what are you referring to?

    I don't think we want to compete with China. It would require a significant drop in standards. For now anyway.

    The Tacoma Narrows Bridge was a freak thing, but IIRC, they were warned that the bridge would fail. It also suffered from budgetary issues and the pilons were only 8ft as opposed to 20ft, or some such. Obviously you need to do your own research if you want more information, but it was also the torsion vibration that doomed it. So cheaply built, as quickly as possible, with the engineering reduced to fit the budget and you get...

    The air will be cold enough to freeze exposed parts of the bridge, but I think it's been a while since Puget sound froze. The water temp stays about 50.

    He's referring to the Alaskan Way Viaduct replacement project, which will be the world's largest diameter tunnel, IIRC. http://www.wsdot.wa.gov/projects/Viad uct/

    Why compete? Here in San Francisco, our new bridge is being built in China.

    FTFY

    Gee, what's the worst that could happen to a floating bridge over Lake Washington?

    /Shouldn't have had it built in Aberdeen. That place sucks.

    Let's do it again!

    It's the replacement tunnel for our Hwy 99 viaduct, which is 1) not up to current earthquake code (true) and 2) too much of an eyesore to replace, according to all the developers who will throw up 20 story condos the second they can in the new area.

    /of course a simple replacement on the exiting footprint was the most cost effective solution

  • But the important thing is that no unions were involved, amirite?

    /could be wrong.
