Chinese builders

 Over the years, China has built numerous roads, underpasses and overpasses.  And one such mission is called Huangjiuan Interchange.  But clearly, this overpass they built in Chongqing is something else.  No wonder it is now known as the world's most complicated overpass.

  Apparently, it is designed in this way in response to the complex transportation needs within the region

  While the Chinese government says it's designed to help drivers not lose their way, I assume otherwise.  It's so complicated that a little carelessness on the part of the driver can send him into the wrong direction and he can spin around cursing himself and the engineers like crazy.
