The largest tunnel in the world: costing 47.25 billion yuan, the highest point is 2,300 meters, running through the lifeblood of the two countries

People always long for freedom in their hearts, want to travel to unfamiliar environments, and let go of themselves. In the 120 countries I traveled to, I have met many tourists, some of whom travel with the same purpose as me, and can work at work. In the spare time, you can also see different local folk customs, and then pick up the camera to record these wonderful events.

But when we go out to play, most of us are inseparable from transportation. Nowadays, transportation is more convenient, but I think our country is more convenient in terms of transportation. In many European countries, they travel When it comes to long distances, we can only rely on trains, but their trains are different from those in our country.

When I traveled in Switzerland, I took a train like this. The top of the train is transparent, allowing us to enjoy the scenery outside. Some people deliberately travel by train to see the Alps, but the train walks, It is inseparable from the construction work. When I took this train to enjoy the Alps, I was shocked by a tunnel called the Gotthard Tunnel. Why should I focus on this tunnel instead of the scenery? Because as far as I know, this is the second tunnel in the world. It runs through the two countries and took 17 years to build at an altitude of more than 1,100 meters. It plays a major role in international traffic.

At that time, on the Swiss side, about 1.2 million heavy-duty trucks passed through the Swiss countryside every year. The exhaust gas not only harmed local rare animals, but also seriously eroded the Alps. Therefore, Switzerland voted to build this tunnel. After the completion of this train tunnel, the number of heavy trucks passing through the Alps will be limited to 650,000!

The construction started in 1999, and it was completed in 2016. Many difficulties were overcome in the middle. When it was completed, the total cost was 47.25 billion yuan. What is even more incredible is that the top of this tunnel also carries more than 2,300 meters of mountains. But it can still bear it, which shows how ingeniously the designer designed this load-bearing structure at that time.

Since the completion of this tunnel, Italy and Switzerland have been shortened by an entire hour. Many travel enthusiasts will come here to check in, because when you enter the darkness from the light and open the light again, you have already crossed the border, and After the completion, the pressure of road freight in Switzerland has been improved, so this railway has received a lot of enthusiasm.

But when you come here to ride, you must experience the train, because the train here is the same as the one at the top of the picture, you can enjoy the unique scenery of the Alps, let you sigh the magic of nature, what do you do about it? What about this tunnel that traverses the two countries?
