Partial Bridge Collapse in Tennessee

Infrastructures are failing, one piece at a time.

This story, Concrete bridge railing collapses onto Tennessee interstate, injuring one person, is unfortunate for the person injured, but instructive for the rest of us. There is a quote in the above article that says "once in a lifetime" event, which is categorically not true. These types of incidents are happening all the time, just not in as dramatic a manner. Hopefully, the bridges are being closed and traffic prohibited before there is a calamity. In my town of Puyallup, Wash., there is an old iron bridge over the Puyallup River. It should have been replaced or closed years ago, but traffic keeps passing over it, and when sitting on the bridge in your car, you can feel the bridge flex when trucks go across it. Maybe it will be replaced, but I do believe we have a "fix on failure" mentality. 

Someone once told me that "Infrastructure is failing, one piece at a time." Like the frog in the pot of warm water, we are not noticing the impacts since the failures are happening across a wide swath of America.
