[POPULAR MECHANICS] How Fragile are Americas Bridges? - Page 2

post #11 of 89
Not too surprising, there was a documentary about our bridges a while back. Most of them are past their original life expectancy and have been poor patched together over the years and not properly maintained. As well they weren't built with the population of today in mind, so already being old and improperly patched, the load is only increasing.

Been quite a few stories on this over the years. Our whole infrastructure ( bridges, electrical, etc ) is at a point where it needs a huge overhaul.

And as with everything, we're failing.

See back in the day they made things to last and they did. Now its about selling products and product life cycles. I know that the TV manufactures build TVs so they last 4 years. They believe every 4 years we will buy a new one.
Obviously Buildings and Structures like bridges are different but I'm guessing they have a town plan that has suggested that a bridge like the one that fell are only got to last x years because the population well be x by then and we will need a new one anyway.

I think you're very confused and over generalizing infrastructure with consumer electronics. Don't know where you get "4 years" from. At this point it sounds more like a personal rant than fact.

It's not whether things lasted longer "back in the day" vs now. It's a matter of how much you're willing to pay. People with your mentality expect to pay little and want things to last forever. You get what you pay for.

Last time I checked cars are still made to last. Passenger aircraft are made to last. Houses are built to last. Heck, my MacBook from 9 years ago is still going strong.

Not to get into politics too much, but WA cut back on road maintenance funding a LOT in the past years. I think all 5 of the bridges around where I live are listed as structurally deficient with no funding to replace or properly fix them.

Its scary stuff, and sadly it will probably require a bigger disaster before any action is done. We've got 60 year old bridges carrying 10x, if not more traffic flow than they were originally designed for.

With everything made today (cars, boats, tvs, computer parts, vibrators) they set out to achieve it and for it to last for a reasonably practicable time. nothing more nothing less. Same with buildings and structures. they could design and build a building that would last 2000 years but they dont. Why because they dont see that as being reasonably practicable. Life expectancy is one of the first things they look at and determine when designing because it under pins the materials, designs and costs.

Everything today is commercial and meant to last a short time so that businesses can do business.

Well i was over in Italy and not the nice parts and their starting to let the place go. I know its an old beautiful cultural country with thousands of years of history but basic things are getting neglected. I feared for my life on the roads.

The irony of a brief power outage happening while cleaning a thread about infrastructure... though it's of a different sort. That said, please stay on topic.
