It revolutionized European transportation by providing a faster and more efficient link between northern and southern Europe.
2. Seikan Tunnel
Located in Japan, the Seikan Tunnel holds the title of the world’s longest tunnel for a single-track railway. This undersea marvel connects the islands of Honshu and Hokkaido, stretching approximately 53.85 kilometers (33.49 miles) beneath the Tsugaru Strait. The Seikan Tunnel is a testament to Japanese engineering excellence and withstands the challenges of earthquakes and typhoons.
3. Channel Tunnel
The Channel Tunnel, also known as the Eurotunnel, links the United Kingdom and France beneath the English Channel. With a total length of about 50.45 kilometers (31.35 miles), it connects Folkestone in England and Coquelles near Calais in France. This remarkable tunnel allows for high-speed train travel, creating a vital transportation link between the two countries.
4. New Guanjiao Tunnel
In China, we find the New Guanjiao Tunnel, an integral part of the Lanzhou-Xinjiang High-Speed Railway. Extending approximately 32.645 kilometers (20.3 miles), this tunnel is located in the Qilian Mountains. It plays a crucial role in connecting the cities of Lanzhou and Urumqi, significantly reducing travel time and enhancing transportation efficiency.
5. Guadarrama Tunnel
Situated in Spain, the Guadarrama Tunnel forms a crucial section of the high-speed rail line connecting Madrid and Valladolid. This tunnel spans approximately 28.4 kilometers (17.6 miles) beneath the Guadarrama mountain range. It showcases Spain’s commitment to modern transportation infrastructure and allows for faster and more convenient travel between the two cities.
6. Laerdal Tunnel
Venturing to Norway, we encounter the mesmerizing Laerdal Tunnel, the longest road tunnel in the world. Stretching approximately 24.5 kilometers (15.23 miles), this tunnel is part of the European Route E16 and runs between Laerdal and Aurland. Its innovative lighting design creates an otherworldly experience for drivers passing through this subterranean marvel.
7. SMART Tunnel
Malaysia’s SMART Tunnel, an acronym for Stormwater Management and Road Tunnel, serves a dual purpose. This tunnel spans approximately 9.7 kilometers (6 miles) beneath Kuala Lumpur, providing a vital traffic link and serving as a stormwater reservoir during heavy rains. The SMART Tunnel showcases Malaysia’s innovative approach to urban infrastructure and flood management.
8. Anton Anderson Memorial Tunnel
In Alaska, the Anton Anderson Memorial Tunnel, often referred to as the Whittier Tunnel, is a remarkable transportation route. Spanning approximately 4.5 kilometers (2.88 miles), this tunnel provides access to the isolated town of Whittier. It accommodates both railway and vehicle traffic, and its unique operational schedule ensures efficient transportation in this remote region.
9. Eisenhower Tunnel
The Eisenhower Tunnel, situated in the Rocky Mountains of Colorado, is a vital passage along Interstate 70. With a length of approximately 3.2 kilometers (1.99 miles), it cuts through the Continental Divide and allows for safe and convenient travel between eastern and western Colorado. This tunnel is a testament to human engineering in challenging mountainous terrains.
10. Zion-Mount Carmel Tunnel
Our final tunnel takes us to Utah’s Zion National Park, where the Zion-Mount Carmel Tunnel offers a breathtaking passage through the sandstone cliffs. With a length of approximately 1.9 kilometers (1.1 miles), this tunnel is an engineering marvel that allows visitors to explore the wonders of the park. Its construction involved carving through solid rock, showcasing human ingenuity in harmony with nature.
