The $5BN Gigantic Tunnel Under London
Why would one of the world's most iconic cities need a secret $5 billion tunnel buried deep beneath its streets? Sounds nuts, right? But hear me out. This video is all about London's brand new underground superhighway called the Thames Tideway Tunnel. It's a ginormous 25 kilometer long tunnel that's going to stop millions of tons of gross sewage from polluting the River Thames every year. But get this - building a monster tunnel that goes under one of the busiest cities on the planet is no joke. How the heck do they dig that thing without crashing into all the pipes, tunnels? Who knows what else is already down there?
