What goes into the building of a concrete bridge? Chad is an engineer in the concrete industry and shows us the process. From assembling a reinforcing cage to discussing the science behind mixing and pouring concrete. In Chad's words, "Concrete is a pretty remarkable material. Stone, sand, water and cement have been used since the Romans were building the Coliseum!"
