Gotthard Base Tunnel: How Switzerland Built the World’s Longest Railway Tunnel

The Gotthard Base Tunnel is the longest railway tunnel in the world, stretching 57.1 km (35.5 miles) beneath the Swiss Alps. Built over 17 years and costing more than $12 billion, it is one of the most ambitious engineering projects ever completed in Europe. In this video, we explore how Switzerland drilled through the Alps to build the Gotthard Base Tunnel and transform transportation across the continent. Engineers had to overcome extreme underground heat, unpredictable geology, and immense water pressure while drilling more than two kilometers beneath towering mountain peaks. You’ll discover: • Why Switzerland decided to build a tunnel through the Alps • The political decision that launched the project • The giant tunnel boring machines used during construction • The geological challenges engineers faced underground • How the Gotthard Base Tunnel changed European freight and passenger travel The tunnel connects Erstfeld in northern Switzerland to Bodio in southern Switzerland, creating a high-speed rail corridor between Germany, Switzerland, and Italy. Trains that once took hours to cross the mountains can now travel beneath the Alps in about 20 minutes, dramatically improving rail efficiency across Europe. Today, the Gotthard Base Tunnel is not just a transportation route — it’s a landmark achievement in modern engineering, infrastructure, and sustainable transport, helping reduce truck traffic and CO₂ emissions in the sensitive Alpine region. FAQ How long is the Gotthard Base Tunnel? The Gotthard Base Tunnel is 57.1 km (35.5 miles) long, making it the longest railway tunnel in the world. Where is the Gotthard Base Tunnel located? It runs beneath the Swiss Alps in Switzerland, connecting Erstfeld in the north to Bodio in the south. When was the Gotthard Base Tunnel built? Construction began in 1999, and the tunnel officially opened in 2016 after 17 years of construction. #Megaprojects #Infrastructure #GotthardBaseTunnel
