A comment made in an a recent NYT article on these new Chinese bridges: https://mobile.nytimes.com/2017/06/10/world/asia/china-bridg...
> "If you don’t build roads, there can’t be prosperity,” said Huang Sanliang, a 56-year-old farmer who lives under the bridge. “But this is an expressway, not a second- or third-grade road. One of those might be better for us here.”
Expressways are sexy and useful if you are driving thru. But...I have the feeling they are overbuilding it in many places while not caring much about the less sexy roads that might improve local lives more. But then, such roads would never be talked about abroad and wouldn't do much for China's prestige (and therefore the official's in charge promotion).
The cars on the expressway have little bearing on the farmers below it. A rice farmer isn't going to be driving a new Audi or even a Toyota, even in rich Zhejiang, but definitely not in guizhou or Hunan.
