A traffic officer in Hangzhou, China, knows his road. A slight depression developed in an intersection, and he noticed right off. He diverted traffic around the crack, even standing on top of it, to prevent cars from passing over it, until traffic cones were brought in. Motorists were not pleased at having to divert.
It only took a few moments for a giant sinkhole to appear and swallow the pavement! If it weren’t for that one diligent cop, there might be someone at the bottom of the hole. -via Arbroath
