They are actually moving ahead on replacing that rusty old bridge that collapsed in the US. Newer bridge designs like to put a lot of weight on narrower supports, so it is important to see how much the rock can take. And the rock there appears to be pretty bad.
This bridge appears to be having the usual problems getting any money, which was the reason the old one collapsed in the first place. I was quite interested in the concept that they hit high-pressure water in one shaft, so they made the next one shallower. Wouldn't you hate having a shaft end right on top of a water pocket?
The general collapse of US infrastructure offers some excitement for us geotechnical engineers, as they have to replace things when they fall. The cities and states just run up more debt to do it!
