The first solutions for getting across a river were stepping stones and timber logs. The first homes were caves.
But caves exist only in certain areas. And big regions of Earth are not near rivers or lakes. That’s where civil engineering comes in. Civil engineers are people who design and build housing, bridges, roads, dams, airports, tunnels, and more. They work on all the building projects we think of as infrastructure.
