Mega Tunnel Disasters: True Horror Beneath the Earth | Engineering by Catastrophe S1

Video Description

"Tunnels can save money, time and the environment. They provide a short cut through landscapes that are difficult to navigate. But tunnels themselves can be dangerous. In the worst-case scenario, a tunnel can turn into a tomb - and today’s tunnels are longer, deeper and more daring than ever before. Into the Depths examines two European mega projects – the longest underground rail excavation – the Brenner Bass Tunnel - and the world’s longest immersed tunnel - the Fehmarnbelt link. As they break records and push boundaries, how can engineers use past disasters to make their tunnels safer for construction workers and motorists?"
