How is a tunnel underwater built?
To use this method, builders dig a trench in the riverbed or ocean floor. They then sink pre-made steel or concrete tubes in the trench. After the tubes are covered with a thick layer of rock, workers connect the sections of tubes and pump out any remaining water.
Are underwater tunnels safe?
Tunnels are far safer. Most tunnels which go under a body of water are so far below the bed of the body of water that little short of a nuclear blast could cause them to flood catastrophically. Even an earthquake is unlikely to cause catastrophic flooding of a well constructed tunnel. Tunnels are far safer.
