S1 E2 | Construction Disasters

Bridges and tunnels revolutionized transportation-but when they fail, tragedy follows. This episode explores the world's worst collapses and fires, including a tunnel blaze in the Alps so intense it fused 20 cars together. While bridge failures send vehicles plummeting into water or ground below, tunnel fires turn confined spaces into infernos. Why do these disasters happen, and what can be done to stop them? As we build bigger and faster, we also raise the stakes.
