Longest Tunnels in the World

BUSINESS - EDITORIAL

Tunnels sometimes go under the sea and reach the opposite shore, and sometimes pass through the magnificent mountains and keep the road going. Some are shorter than ten meters, while others continue for kilometers. Some are built exclusively for rail transport systems, while others ensure the flow of vehicle traffic. In fact, most of the longest tunnels in the world were built for water distribution. Metro systems are another long tunnel system. There are many different types, sizes, and lengths of tunnels, but the common feature of all is that they are the result of the use of human intelligence and engineering to overcome difficult natural conditions.

Whether it is rail, road, metro, or water supply tunnel, building a tunnel is a very difficult and demanding process. However, the advantages it brings are so great that building a tunnel is very efficient, albeit difficult. The operational management required for both the building process and keeping the tunnel safe and functional is very difficult. And in the longest tunnels in the world, this difficulty manifests itself in a completely different dimension. Gas accumulation, the risk of natural disasters, reaching the scene in possible accidents, lighting, and many more challenges that we never think of all occur even more prominently when it comes to the world's longest tunnels.

Whether they are built for vehicles, subways, trains or high-speed trains, tunnels are the construction wonders we always look forward to getting out of. We have put together the longest tunnels in the world and listed them for you. Although they are not among the longest tunnels in the world, we use many tunnels while driving in our daily lives. As we enter the tunnels, let's turn on your car headlights, check the speed and follow the speed rules, and be prepared for the sudden light intensity at the tunnel exit.
