Why America Freezing the Hudson's Riverbed to Dig a $16B Tunnel?

🎬 FULL NAME : Why America Freezing the Hudson's Riverbed to Dig a $16B Tunnel? 👍 Subscribe for deep dives into the world's biggest megaprojects — and what happens when they fail. New investigations every week. Every train into Penn Station from the west runs through two tubes opened in nineteen ten. In twenty twelve, Superstorm Sandy flooded both of them with salt water. The water was pumped out within days. The salt stayed, and it has been attacking the steel and concrete inside the structure ever since. The old tubes cannot simply be closed for repair: taking one out of service cuts capacity by up to seventy-five percent. So America is building a new crossing first. Two new tubes through the ancient rock of the Palisades, under the streets of North Bergen and Union City, beneath the soft bed of the Hudson River and into the buried waterfront of Manhattan's west side. ⏱️ TIMECODES : 0:00 A machine built in a pit 2:24 Inside the launch box 3:35 How a boring machine really works 5:40 Cutting through the Palisades 9:01 The 1910 tunnels and the salt 11:48 Under the Hudson: frozen ground and buried ships 15:51 A tunnel box built with no money 16:52 When the money stopped 18:32 Four tracks and a race against salt #HudsonTunnel #Megaprojects #Engineering #GatewayProject #NewYork #TunnelBoringMachine #Infrastructure #Documentary
