On March 9th, the 28th Bridge of the 10th Highway Reconstruction Project, the "first high bridge" in Cambodia constructed by China Road and Bridge Corporation, was successfully closed, marking a major milestone victory for the project and laying a solid foundation for its subsequent operation. The first high bridge in Cambodia, Helong. The China Road and Bridge No. 28 Bridge, with a total length of 530 meters and a height of 80 meters, spans the valley of the Elesai River. After completion, it will become the highest pier bridge and the first elevated bridge across a mountain ridge in Cambodia. The bridge is adjacent to a national nature reserve and a first-class water source protection area, making construction difficult and posing high safety risks. The project team has overcome difficulties such as deep foundation pit excavation and river construction, and developed more than 10 new technologies such as automatic walking of hanging baskets and wireless temperature monitoring, which have improved construction safety and engineering quality. The main span closure is the most technically difficult, safety risky, and quality controlled key process in bridge construction, which directly affects the stress condition and alignment control of the entire bridge Liu Zhaowei, the project leader of China Road and Bridge Corporation Cambodia Office 1551, introduced that the project team relies on digital technology to monitor the bridge structure alignment in real time, and ensures the smoothness of the alignment through theoretical analysis and verification, ultimately achieving "millimeter level" error control. It is reported that the reconstruction project of Highway 10 has a total length of 197.363 kilometers, with double layered asphalt pavement for general sections and reinforced concrete pavement for bends. At present, the overall project has been completed by 96.16%. Highway 10 is an important national road connecting Battambang Province, Bodhisattva Province, and Guogong Province, and is crucial for the transportation and export of grain in Battambang Province, the "granary" of Cambodia. The first high bridge in Cambodia, Helong. China Road and Bridge Corporation's Minister of Public Works and Transport of Cambodia, Bin Pony, stated that after the completion of the project, it will further improve the road network in western Cambodia, enhance road standards and overall service levels, and greatly drive economic development in the western region.
