Exploring the World’s Longest and Most Expensive Tunnel: A 35-Mile Journey costing £9.6bn – World News

The Gotthard Base Tunnel in Switzerland, known for being the world’s deepest and longest tunnel, faced a major setback in 2023 when a train derailed inside, causing it to be closed. This remarkable tunnel, stretching 57 kilometers and costing a staggering £9.6 billion to build, was a monumental engineering feat that opened to much fanfare in 2016.

Burrowing 2,300 meters below the surface in the Swiss Alps, the tunnel was a game-changer in reducing travel times between Zurich and Milan to just two hours and 40 minutes. Constructed with the goal of boosting the Swiss economy by connecting regions more efficiently, the tunnel accommodated approximately 260 freight trains daily, contributing significantly to the national economy and the environment.

However, disaster struck in 2023 when a train derailment caused severe damage, leading to the closure of the tunnel. Only one tube of the tunnel has been reopened, prioritizing freight trains, with full restoration not expected until September. This incident highlighted the challenges and risks associated with operating such a massive infrastructure project.

Despite the setback, the Gotthard Base Tunnel remains a testament to human ingenuity and strategic planning, showcasing the remarkable capabilities of modern engineering. The tunnel’s closure serves as a reminder of the importance of safety and maintenance in ensuring the smooth operation of critical transportation infrastructure.
