The construction process of the Libu Yangtze River Highway and Railway Bridge in Jingzhou, Hubei Province, as the world's largest double decker cable-stayed suspension system bridge, has always been highly anticipated. Recently, this magnificent bridge has officially entered the main tower construction phase, marking another solid step in the project's construction.

The Libu Yangtze River Railway Bridge is located in Jingzhou City, Hubei Province, with Libu Town on the north bank and Mishi Town on the south bank. The total length of the bridge is about 7.9 kilometers, of which the main bridge across the river is 1723 meters long. Its design not only reflects the progressiveness technology, but also fully considers the needs of environmental protection. To avoid the impact of bridge piers entering the river on the ecological environment and protect the biodiversity of the Yangtze River Basin, the bridge adopts a construction plan that spans the river, which is also rare in the world.

During the construction phase of the main tower, the construction of the north main tower of the bridge has been completed, and comprehensive tower body construction has begun. The north main tower reaches a height of 215.5 meters and is based on drilled cast-in-place piles with a diameter of 2.5 meters. There are a total of 90 piles arranged in a row. At present, the top surface of the tower has exceeded the average water level of the Yangtze River, indicating that the construction of the tower body will proceed smoothly, and it is expected to achieve topping out next year.

In addition to the construction of the main tower, other parts of the bridge are also in full swing. The construction of the main tower pier on the south bank has been completed, and the first concrete pouring construction of the south bank anchor shaft has also been completed. In addition, significant progress has been made in the pile foundation construction of the bridge, with the project completing 51% of the total pile foundation construction, laying a solid foundation for subsequent construction.

The construction of the Libu Yangtze River Bridge is not only a transportation project, but also an important measure to promote local economic and social development. As the southern extension of the Jingmen Jingzhou Railway, the realignment of the Erenhot Guangzhou Expressway in Jingzhou urban area, and the control project of the Jingzhou urban road network, the completion of the bridge will greatly improve the backbone road network structure of the Yangtze River Economic Belt, enhance the flood control and rescue capabilities of the Jingjiang flood diversion and storage area, promote the integrated development of Jingzhou across the river, and promote Jingzhou to build a regional central city in central Hubei Province.
