We can build bridges and “install” them faster, cheaper, and with less disruption than in the past.

Also, the headline for this article is wrong: our infrastructure is not crumbling. At least, not systematically.

Finally, and perhaps most importantly (at least, the main non-bridge-y reason why I read and then posted this article): what does this mean vis a vis the concept of “sustainability“? As I have written in the past, one of the biggest problems with the concept of sustainability is that we should not project into the future behaviors, technologies, products, and the attitudes of today (which is, in reference to my calling this a problem, what pretty much everybody who talks about sustainability actually does). We can build and install bridges cheaper now than yesterday. So, whatever yesterday’s budget (in terms of dollars, time, waste, whatever) for fixing bridges was, it’s no longer a good budget for today. The world of 2100 is going to be much different than the world of 2013 so why in the world do we care if anything that we do today is “sustainable”? Even if it is “sustainable”, the fact is it won’t be sustained in 100 years.
