The New Yalu River Bridge is an important transportation hub connecting China and North Korea, located between Yanbian Korean Autonomous Prefecture in Jilin Province of China and Rason City in the Democratic People's **** and State of Korea. The bridge is a symbol of friendship and cooperation between China and the DPRK and an important link for exchanges and cooperation between the two peoples.

1.Background of Construction

With the continuous development of the relations between China and North Korea, it has become imperative to strengthen the transportation links between the two countries. As early as 2010, the two governments began to discuss the plan to build the new Yalu River Bridge, and the construction of the project was officially launched in 2013.

The construction of the new Yalu River Bridge is of great significance in promoting the economic development of China and the Democratic People's Republic of Korea (DPRK) and strengthening humanistic exchanges between the two countries. The completion of the bridge will shorten the distance between China and the DPRK, facilitate exchanges between the people of the two countries, and promote trade cooperation and tourism between the two countries.

2. Project Planning

The total length of the new Yalu River Bridge is about 5.2 kilometers, of which the main bridge is about 3.1 kilometers long and the auxiliary bridge is about 2.1 kilometers long. The main bridge adopts a suspension bridge structure, while the auxiliary bridge adopts a cable-stayed bridge structure. The whole bridge is a strategically important cooperative project invested by both China and North Korea.

To ensure the safety and reliability of the bridge, the engineering team adopted advanced design and construction techniques. First, they conducted detailed geological surveys and engineering investigations to ensure the stability of the bridge. Second, they selected high-strength construction materials to enhance the bridge's load-bearing capacity. Finally, they supervised and managed the construction process in strict accordance with the design requirements to ensure the quality of the project.

3. Construction process

The construction process of the new Yalu River Bridge can be divided into three main phases: foundation construction of the piers, construction of the main and auxiliary bridges, and decking and opening to traffic.

First, the pier foundation construction is the foundation of the whole project. The engineering team constructed pier foundations on both sides of the bridge to support the girders of the main and auxiliary bridges. In order to ensure the stability of the piers, the construction crews used advanced technologies such as deep pit excavation and grouting piles.

Next came the construction of the main and auxiliary bridges. The engineering team built the towers and piers of the main bridge, and then utilized large cranes to lift the main girders of the main bridge into place. The construction process for the auxiliary bridge was similar to the main bridge, but on a smaller scale. Throughout the construction process, the engineering team worked in strict accordance with the design requirements to ensure quality and safety at every step.

Finally, there is the bridge deck laying and opening phase. Once the construction of the girders for the main and auxiliary bridges was completed, the engineering team started the decking work. They chose high-strength reinforced concrete materials to ensure the bearing capacity of the bridge deck. Finally, when the bridge deck was paved and passed safety tests, the new Yalu River Bridge was officially opened to traffic.

4. Transportation benefits

The completion of the new Yalu River Bridge will bring great transportation benefits. First of all, it will shorten the distance between China and North Korea and facilitate people's transportation. Both business trips and sightseeing will be more convenient. Secondly, the completion of the bridge will promote trade cooperation between the two countries. Commodities and goods from China and North Korea will be more conveniently transported to each other's countries, promoting economic development. At the same time, the bridge will also promote exchanges and cooperation between the people of the two countries and deepen their friendship.

5. Conclusion

The completion of the new Yalu River Bridge marks a new milestone in the friendship and cooperation between China and North Korea. The bridge is not only a transportation hub, but also a symbol of friendship between the two peoples. It will provide important support for the economic development, humanistic exchanges and friendly cooperation between the two countries. It is believed that under the connection of the new Yalu River Bridge, the cooperation between China and the Democratic People's Republic of Korea will usher in a brighter future.
