The 5 Longest tunnels in the world

Published

on

The first milestone in the construction of the tunnels was the completion of the first modern tunnel in London under the River Thames in 1843. With its opening, World Engineering took a major step toward modern systems of transportation. Being able to build roads under geographic barriers such as rivers and mountains, without the need to move around them, opened the door for human transportation systems to go (almost) anywhere.

Since then, tunnels have become one of the most useful infrastructures when planning highways and railroads. They make it possible not only to defeat mountain-shaped obstacles (literally) but also to hide urban traffic underground, thus significantly reducing the length of roadways. Because in 2022, as it was in 1843, the shortest distance between two points is still a straight line.

The tunnel under the Thames was a great advance in transport planning but was by no means the culmination of digging into the earth’s surface to move things. In the nearly 200 years since then, tunneling has continued, making it possible to achieve some impressive works of engineering. The 5 longest tunnels ever built (to date) are as follows.

1.-Leardle Tunnel

With its 24.5 kilometers, the Laerdal Tunnel is the longest in the world, crossing several mountain formations between Laerdal and land in western Norway. Construction work began in 1995 and ended in late 2000. Due to its length, which takes 20 minutes to cover, the lighting system is designed to remove any tension between drivers. The resulting light gives the impression of daylight and is so spectacular that it has inspired some people to hold their weddings inside the tunnel.

Along with the tunnel, the separate caverns make it possible to reverse direction as well as rest so that the route is not too difficult. Even if there is no safety exit, telephones or firefighters along the way may activate some flashing signs warning other drivers that they should proceed to the nearest exit.

2.-Yamate Tunnel

At 30 meters below ground, Yamet in Japan has a total distance of 18.2 kilometers. Construction began in 1992 and the first section was opened in 2007, with the entire length being opened in 2015. The Yamate Tunnel comprises the central circular route of the Tokyo Toll Road, most of which is under the city’s Yamate Street.

In addition to being the second longest tunnel in the world, Yamate also has the honor of being the longest urban tunnel on the planet.

3.- Zhongnanshan Tunnel

The Zhongnanshan Tunnel crosses the Qinling mountain range between Bataur and Beihai in southern China for a distance of 18 kilometers. It was the longest tunnel in Asia until seven years after it opened in 2007. It is part of the Xi’an Ankang Highway, which connects the counties of Chang’an and Zhashui. Due to its location under the Qinling Range, it is 1,640 m below ground at some points.

Parts of the tunnel have artificial plants and colored lights to prevent drivers from falling asleep at the wheel, having traveled such a long distance below the ground.

4.- Jinpingshan Tunnel (China)

The Jinpingshan Tunnel in China has a total length of 17.5 kilometers and is located in Sichuan Province. The tunnel leads to Jinping Dam (the highest in the world) and is not open to general traffic: it is only crossed by authorized vehicles. For this reason, relatively little is known about the tunnel.

Part of it is at a depth of 2,375 meters because it is just below the Jinpingshan Mountains, making it the second deepest tunnel in the world.

5.-San Gottardo Tunnel

Switzerland’s San Gottardo Tunnel is part of the A2 motorway between Basel and Chiasso. When construction was completed, it was the longest tunnel in the world at 16.9 kilometers. It was built from the 1970s to the 1980s and finally opened in September of 1980.

Between its opening and the end of 2005, there were approximately 900 traffic accidents. The most serious incident occurred in 2001, resulting in a fire that necessitated a redesign of the system to prevent a similar accident. From late 2001 until 2002’s reopening, there is only one-way driving (alternating every two hours in each direction).

On the other hand, a modification to the cylinder head frequently affects the gasket’s ability to provide a reliable seal. The deterioration of the gaskets is also significantly influenced by age. After some time, they start to lose capacity and quality.

Keeping the importance of engine process in mind, a gasket is not something that you should neglect. A deteriorated gasket cannot maintain the pressure that is probably highlighted in lack of engine power.

Additionally, oil and coolant passageways might start to leak in unintended places. Engine overheating may result from coolant entering the combustion chambers, which mixes and dilutes the engine oil and reduces the cooling capacity of the cooling system.
