The $9 Billion Lyon Turin Base Tunnel Explained

Europe is building one of the most ambitious engineering projects in modern history, a 57.5 km railway tunnel carved deep beneath the Alps. The Lyon Turin Base Tunnel will become the longest rail tunnel on Earth, connecting France and Italy while transforming freight and passenger travel across Europe. This documentary explores how engineers are drilling through one of the most difficult geological environments on the planet, why the project costs billions, how massive tunnel boring machines operate underground, and why this single tunnel could reshape Europe’s transportation network. From 500 meters below the surface to a 2033 completion target, discover the technology, challenges, costs, and future impact behind Europe’s hidden mega project. 00:00 Europe’s Hidden Mega Tunnel Under The Alps 00:38 Why Europe Needed A New Alpine Railway 01:20 How The Base Tunnel Changes Transportation 02:06 The Full Lyon Turin Railway Project Explained 02:50 Engineering Design Behind The 57.5 KM Tunnel 03:25 The Extreme Geology Engineers Face 04:04 The Giant Tunnel Boring Machines 04:47 How The Tunnel Is Built Underground 05:37 Construction Progress And Current Status 06:52 The Real Cost Of Europe’s Mega Project 07:31 Opposition And Controversy Around The Tunnel 08:41 Why The New Tunnel Is Necessary 09:12 Recycling Millions Of Tons Of Excavated Rock 10:05 Safety Systems Inside The Tunnel 10:40 How It Connects Europe’s Transport Network 11:30 Why This Tunnel Matters For The Future 12:12 Jobs And Economic Impact 12:40 The Future Of Europe’s Longest Rail Tunnel ✨ 𝐉𝐨𝐢𝐧 𝐆𝐢𝐠𝐚 𝐁𝐮𝐢𝐥𝐝𝐬✨ https://www.youtube.com/@UCkWQEhTxV2lg_YM31qnk-IQ 🍁 𝐀𝐛𝐨𝐮𝐭 𝐆𝐢𝐠𝐚 𝐁𝐮𝐢𝐥𝐝𝐬🍁 Welcome to Giga Builds, where we explore the world’s most incredible construction projects, mega structures, and engineering achievements.
