Why is the only bridge in China that can't be photographed always on alert, and all passing cars will whistle?

With the development of industrialization and modernization, mobile phone has become an indispensable tool for people, and it has also changed from the initial pension machine to the current smart machine. Smart phones have many uses, such as taking photos and videos online. , and has various functions. Because when traveling, people love to take pictures, not only of themselves, but also of scenic spots. But some places are not allowed to take photos, such as museums, because taking photos will damage the cultural relics inside, which have existed for a long time, and taking photos is likely to inadvertently damage this cultural relic. Mobile phones have advantages and disadvantages. Advantages can help us record all kinds of things, but they can also make us addicted and disturb our work efficiency.

Because the camera is huge, most people choose to take their smart phones when traveling, because it is not only easy to carry, but also can take beautiful photos. But there is such a scenic spot that no photos are allowed. It's just a bridge. Vehicles and tourists passing through this bridge should be inspected one by one, and photos are not allowed to flow out. This bridge is the Nujiang Bridge. Not only is it forbidden to take pictures here, but the army also takes turns to help. All passing cars need to honk. Why is this bridge not allowed to take pictures? What's the story behind this? What happened to him? What is the function of this bridge? Isn't it just for the convenience of people?

Nujiang Bridge, located in Nujiang, China, started construction on 1988 and was officially put into use on 199 1. At that time, construction was extremely difficult. The whole bridge is 678m long and15.8m wide, which is the lifeline of local traffic. Flow alone cannot explain its function. It is also an important military passage, because Yunnan borders some countries in Southeast Asia. If there is some emergency, it can arrive quickly and find out the reason. The most important thing is to avoid revealing military secrets and bring some losses to the country. People passing by here are not allowed to take pictures. In addition, the topography of Yunnan-Guizhou Plateau is relatively complex and there are many karst landforms. The Nujiang Bridge has been built for 28 years, and all kinds of vehicles pass through it all the year round. The task is arduous, so it has also caused losses to varying degrees.

20 10 Nujiang bridge has also been strengthened and maintained. During the construction period, traffic control was implemented on the bridge, and vehicles were forbidden to pass, just to ensure the safety of local vehicles, because the Nujiang River is fast-flowing, and once it falls, it is likely to end up in a bad end. Due to the local topography and rugged surface, it was extremely difficult to build the Nujiang Bridge at the beginning. Although China has rich experience in bridge construction, before the completion of the Nujiang Bridge, he made various investigations on the Nujiang River and did a lot of preliminary work. In order to prevent the quality problems of Nujiang Bridge, tanks were dispatched to test the quality of the whole bridge. But why do passing cars honk their horns? It is because a soldier was sacrificed when the Nujiang Bridge was built, and this soldier was also buried here. The car honked its horn to pay tribute to the soldier.

Going out to travel and take photos is because everyone wants to record this unusual beauty and want to leave their memories here. But because different places have different requirements, some places are not allowed to take pictures, such as some Buddhist temples or ancestral temples. Nujiang Bridge is the only bridge in China that is not allowed to take photos, not only because it is an important transportation hub in southwest China, but also because it is a famous military passage. In order to prevent the unpredictable consequences of military leaks, people in the past were not allowed to take pictures. Even people passing by here will be checked by the armed police to ensure that nothing is lost. It is precisely because of this serious and responsible spirit that we can better protect our military secrets and protect local people. Perhaps the Nujiang Bridge is not very famous, but it is because of its existence that the exchanges between the East and the West are more frequent and close.

The armed police stationed in the frontier are conscientious. These soldiers stood silently under such harsh conditions. Although the living conditions are much better now than in the past, there are still many unpredictable things, such as altitude sickness. Everyone's physique is different, and so is his endurance. So in the face of altitude sickness, some people are likely to die without treatment. For these armed police officers and soldiers stationed in the plateau, the most important thing is to protect themselves. For the construction of Nujiang Bridge, these officers and men have also made a lot of efforts. Because of its extremely important strategic position and complex terrain, during the construction process, the military and civilians cooperated with each other to build the Nujiang Bridge. China's bridge-building technology has always been at the advanced level in the world. Now in China, all kinds of bridges have been built in many places, which can connect the north and the south and connect things.

However, the once Nujiang Bridge, under the erosion of years, has already taken on a new look. Tourists who walked along this road in earlier years said that the Nujiang Bridge is not magnificent, and its length is only tens of meters. As the main road connecting Sichuan and Tibet, it is steep and desolate, and is called "the most inhospitable environment". But it is here that a group of officers and men are stationed all the year round. Waiting in the endless barren hills, keeping company with the scorching sun.

At that time, as the throat of National Highway 3 18, Nujiang Bridge was extremely important, so the section near Nujiang Bridge belonged to the military control zone. When the armed police are on duty, they can't take pictures when crossing the Nujiang Bridge, and the speed can't be too fast. The road surface of Nujiang Bridge is not good, so people who pass through Nujiang Bridge are generally frightened. At least 300 cars cross the Nujiang Bridge every day, which makes the Nujiang Bridge even more important.

The Nujiang Bridge is broken in this way, and the only line between Sichuan and Tibet is broken. Therefore, you can't get off and park here. You can only drive a few hundred meters away from the Nujiang Bridge to stop. Even so, after the Nujiang Bridge was opened to traffic with high intensity all the year round, cracks and layout peeling still appeared. In order to prolong the service life of Nujiang Bridge, the 20 10 Nujiang Bridge was completely closed for three times. During the closure period, vehicles have to bypass the Mabu River, which originally took only one minute, and it has become 15 minutes. This shows that the Nujiang Bridge is still very important.

In many remote areas of China and areas with very complicated terrain, there will still be many bridges instead of many roads, because roads in these areas are not convenient to build roads, such as the karst landform in Yunnan-Guizhou Plateau. However, if roads are built in Tibet and other areas, it is necessary to get through the mountains, which will easily lead to mountain collapse, which is extremely troublesome and consumes more manpower and financial resources. If you build a bridge, you don't have to worry so much. You just need to investigate the terrain and study the characteristics of the soil. The completed bridge can better serve local people, promote local economic development, and open up closed and backward small mountain villages, which China has been doing in recent years, and has greatly improved the level of bridge construction in China.

Although the photos taken can be a permanent memorial, sometimes they are far better than those seen with eyes. After all, some photos can't be taken by every mobile phone and camera, and only the naked eye can appreciate the beauty and feelings more deeply. Just like the Nujiang Bridge, people are not allowed to take photos, but the scenery near this bridge is extremely beautiful and surrounded by mountains, but here we can feel the smallness of human beings and the greatness of nature, and we can have a deep awe of nature, and at the same time we can feel the strength of the motherland and the strength of military power.
