1. Which country has the longest tunnel in the world ?
- A
Switzerland
The world's longest tunnel through the Alps has been completed in Switzerland.
The Alps are one of the most beautiful and poetic mountain ranges in the world today. However, this mountain range also faces major obstacles in terms of limited traffic conditions, preventing the development of many economic centers such as Zurich, Turin and Milan. For that reason, the Swiss government decided to spend about 10.3 billion USD in nearly 2 decades to complete the Gotthard Base tunnel, the longest in the world, through the Alps. Previously, the record for the longest tunnel in the world belonged to the Seikan Tunnel in Japan with a total length of more than 26km. - B
