What are the 10 longest tunnels in the world?
Tunnels are some of the most amazing marvels of engineering. But the world's longest tunnels are definitely not the place for a car to break down. The great breakthrough in engineering and construction has ensured infrastructure today with a high level.
The tunnels on this list are the longest ones in the world. Some of them go through mountains and even water to meet the needs of highways and roads. But all of them handle traffic in efficient ways. Tunnels are real architectural wonders that are likely to originate from the caves that the ancient people used as their homes. Then tunnels were used as secret passages, usually underground, as well as a shelter from the enemies. In our days, the tunnels are built for other purposes: they allow people to move in the most inaccessible places. Some of them have overcome technological challenges and numerous geographical and morphological difficulties.
