The first bridge over Wanli Yangtze River with cars at top and trains at bottom, China's first dual-use road-rail bridge.

Some people say that if you consider life as a kind of statistic, then there are a number of bridges that a person must cross in his life. If you prematurely finish bridge you want to cross in this life, then your life will come to an end, and you will step on last bridge of your life.

This is a superstitious view, but it is enough to understand importance of bridges. We also cannot ignore bridges, there are various bridges in our country now, some of which are connected to two very important places.

Some of them have an original design and structure, and some are important cultural heritage from ancient times. But have you ever seen such a bridge?

This bridge can carry both cars and trains. They go hand in hand and ships can pass under train. What is this bridge? Is it just a playhouse in imagination of children?

(1) Wuhan

This place should be familiar to everyone, it's a well-developed big city. Even many stars gave concerts here. But what everyone doesn't know is that Yangtze River flows through this area and divides it into two parts, and connecting two parts is not an easy task.

In early days of founding of New China, Wuhan was not very developed. But region has important geographical advantages. Because we are talking about economic development between south and north of China.

If you want to achieve a smooth development of country's economy, you must solve problem of traffic between these two regions so that goods can move more smoothly.

Therefore, before founding of country, unique geographic location of this region due to north and south has always been a more important issue. Many researchers also hatched idea of ​​building a bridge here, but in fact they decided to start building it after formation of People's Republic of China.

(2) Bridge over Yangtze River in Wuhan

After formation of People's Republic of China, problem of Wuhan's development is inevitable and must be resolved. Therefore, country also made a decision and decided to improve communication difficulties between two areas here, and decided to build a bridge across Yangtze River between these two areas.

However, development of domestic science and technology has just begun, no significant improvements are observed, despite fact that many specialists have returned from abroad, they lack practical experience. At that time, relations between China and Soviet Union were still in a friendly stage, so other side sent many specialists to help our country's scientific researchers to conduct field research.

After field research, it turned out that building a bridge in this area is not difficult. But difficulty is that if bridge meets only current needs, it is easy to build. But if you want to meet needs of future development, you need to think long term.

Firstly, there are two very important railways running on both sides of Yangtze River. If bridge can pass railway through it, it will be more beneficial for development of region. It can ensure smooth transportation of goods, make communication between two regions more frequent, and also radiate to most of China's inland regions.

Therefore, at suggestion of Soviet specialists, our country began to consider this problem. The Soviet specialists gave a plan, which is to use upper tier of bridge to open cars along upper and lower structure, and build railways at lower level so that railway can pass on lower level.

The bottommost layer is hollowed out and spans both sides of Yangtze River in form of an arch bridge, without affecting passage of large cargo ships below, so that three modes of transport can be realized on one river and one bridge on at same time.

(3) Construction challenges

Soviet specialists at that time really thought about China, but then relations between two countries deteriorated, they were forced to return home.

As a result, Chinese specialists officially took over reconstruction of this project. At that time, China had a lot of waste waiting to be completed, and what was considered technically achievable was full of difficulties in implementation phase.

So after construction began, Mao Yisheng, a Chinese expert, led team and devoted himself to construction day and night. It took two years to repair bridge over Yangtze River.

So while we have many bridges that could cross Yangtze River today, decades later, none of them can replace joy and joy this bridge brought us at time.

(4) Shui Tiao Ge Tou

When our great leader Chairman Mao learned of this incident, he was very grateful for difficulties in building this bridge. Thus, this place has a special relationship with Chairman Mao, and people can still see scenes of Chairman Mao bathing in Yangtze River in many documentaries.

The place where its chairman swims is current bridge over Yangtze River in Wuhan. After Chairman Mao saw that Yangtze River Bridge in Wuhan was about to be successful, he thought that convenience this bridge would bring to people of Future was truly a creation that crossed ages.

That's why I came here specifically to cross Yangtze River, and created song-melody of water that we know now. In following decades, many tourists still come here to see place where chairman swam to commemorate chairman.

Decades later, bridge is still as strong as ever, and according to field studies by experts, bridge can still serve people for hundreds of years.
