The construction of the Huangjuetuo Yangtze River Bridge, a high-profile world-class bridge, has recently made a key breakthrough. After careful planning and execution, the main towers on the north and south banks of the bridge successfully realized the cross-river docking of the pilot cable, which marked the construction of the bridge officially entered a new stage of superstructure construction.

As an important part of the Chongqing-Changzhou high-speed double-track connecting road, the Huangjuetuo Yangtze River Bridge adopts a unique single-span suspension double-tower three-span continuous steel truss suspension bridge design, with a total length of an astonishing 765 meters, and the main span is even more than 0 meters, setting a record for the world's largest dual-purpose suspension bridge.

During the construction of the pilot cable across the river, the project team faced multiple challenges, such as the busy shipping of the Yangtze River waterway and the huge river span. In order to overcome these difficulties, the project team innovatively adopted the "traffic boat surface towing method" and chose a 900-meter-long Dyneema rope as the pilot cable. This high-strength special rope not only has buoyancy characteristics and can withstand huge traction tensions, but also effectively prevents sinking and entanglement of underwater obstacles, thus minimizing the impact of construction on the golden waterway.

On the day of construction, under strict navigation control, the traffic boat on the south bank smoothly towed the pilot cable across the river. When the pilot cable is successfully connected to the north bank, the winches on both sides of the river work together to accurately lift the rope to a design height of 55 meters above the river surface. During the whole process, the project team worked closely with the maritime department, equipped with a number of emergency vessels, and ensured the safety of the operation through tension monitoring throughout the process.

The successful crossing of the pilot cable is a key step in the construction of the suspension bridge. From this point in point, the construction party will gradually replace it with a larger diameter transition cable, build a single-line reciprocating traction system, and finally erect a catwalk platform across the river. The successful completion of this milestone node has laid a solid foundation for the subsequent core processes such as the erection of the main cable and the hoisting of the steel truss girder.

The construction of the Huangjuetuo Yangtze River Bridge is not only a technical challenge, but also a great test of the team's wisdom and collaboration ability. From the crossing of the pilot cable to the subsequent construction process, each step requires careful planning and execution. It is believed that with the joint efforts of all the project team, this world-class bridge will be completed and opened to traffic as soon as possible, making an important contribution to the convenience and development of regional transportation.

With the continuous deepening of the construction of the bridge, we also look forward to the Huangjuetuo Yangtze River Bridge to show its magnificent posture as soon as possible, become an important channel connecting the two sides of the strait, and bring a more convenient and comfortable experience to people's travel.

At the same time, we should also praise the hard work and selfless dedication of the project team. It is their hard work and perseverance that give us the opportunity to witness the birth and growth of this world-class bridge.
