en.Wedoany.com Reported - Recently, the highway project from Lajiu Township through Zhongwa Village to Sama Village in Luolong County, Tibet, constructed by China Railway's subsidiary China Railway First Group, passed acceptance, solving the travel difficulties for two remote villages in eastern Tibet.

This project is a key node of Changdu City's "14th Five-Year Plan" village connectivity project. The original road was merely a simple gravel path, serving as the only route connecting Zhongwa Village and Sama Village to Lajiu Township, and also the optimal route for villagers to reach Luolong County. The renovation project spans 37.365 kilometers with a road width of 3.5 meters, designed to highway secondary load standards, covering multiple works including road intersections, bridges and culverts, subgrade, pavement, and traffic safety facilities. The route traverses high mountains and deep valleys with steep terrain and complex geological conditions, at an average altitude of 4,300 meters, with thin air, extreme temperature differences, and frequent snowstorms posing significant challenges to construction.

During construction, the project team of China Railway First Group innovatively adopted high-altitude adaptive construction techniques, optimized subgrade filling processes, enhanced frost-resistant design of bridge and culvert structures, and minimized the impact on the ecological environment. This project was the first among 23 rural road construction projects in Changdu City to complete completion acceptance, and as a representative project, it earned China Railway First Group an AA rating in the 2025 credit evaluation of key highway construction enterprises in the Tibet Autonomous Region.
