Concrete chicane keeps drivers on the curvy and narrow in China

We don't have much information on this, but apparently this theme-park looking concrete chicane is in use on a roadway in China to keep speeds down. The Not So Great Wall of China is about two-feet high and one-hundred serpentine feet long.

We can't imagine what people were doing on this road to necessitate one-way traffic slowed to a crawl. Or maybe the authorities are just trying to protect the trees and fields from pilots like the amphibious Audi R8 driver, since there doesn't seem to be a mammal anywhere in the area. Or perhaps a new Olympic sport? If you have any better (more educated) ideas, please feel free to fill us in in the comments...
