We'll watch the action of the five superstar tools of tunnel construction--the rock drill, explosives, the tunnel boring machine, the gas detector, and the shotcrete gun.



In this episode, we dig deep into the workings, history, and technology of the superstar tools that enable us to burrow beneath the earth. Tunnels--underground, through mountains, beneath oceans and rivers--are among engineering's great achievements. Workers must create a seamless and waterproof space where only unforgiving rock existed before. We'll visit one of America's biggest tunnel projects, Atlanta's CSO (Combined Sewage Overflow). To help manage waste water during torrential rains, two four and a half mile long tunnels are being constructed under the city to channel storm water overflow to a pumping station. What began as backbreaking labor with a simple hammer and chisel is today a state-of-the-art hi-tech industry thanks to the ever-improving technology of these five essential tools.
