It’s a story that drives tour guides and historians of engineering crazy. A worker falls into a pool of wet concrete that’s being poured as part of a major construction project. Before he can be saved, his body slips beneath the surface and he drowns in the thick soup of the concrete. It’s too difficult to extract the body and the construction bosses don’t want to stop the “concrete pour,” so he gets entombed in the concrete pillars of the bridge, or the concrete walls of the dam, or whatever it is they’re building. Were bosses that cold? Was the march of progress so heartless? Find out, Buzzkillers.
