On October 31, the final pile foundation of the second China-Mongolia cross-border railway bridge (section within China) was completed at the Ganqimaodu Port in Inner Mongolia. With this, all 340 pile foundations for the section have been successfully finished, laying a solid foundation for the subsequent construction of the bridge’s main structure.
The China-Mongolia cross-border railway is the second railway linking the two countries, following the Erenhot–Zamyn-Uud line that opened in 1956, nearly 70 years ago. The groundbreaking ceremony for the new railway was held at the border port on May 14 this year, and on June 15, drilling began for the first pile foundation, marking the project’s transition into the construction phase.
During construction, CHN Energy Baoshen Railway Group optimized the construction plan and adopted a 24-hour rotating shift system with full-time technical supervision to strengthen coordination and process control, ensuring the quality of pile foundation work. The section of the project within China is invested and constructed by CHN Energy, while the section within Mongolia is invested and constructed by Tavantolgoi Railway LLC. Both sides adhere to the principle of unified design, respective construction and simultaneous connection.
Once completed, the China-Mongolia cross-border railway will connect the Ganquan Railway with Mongolia’s southbound railway network, further enhancing infrastructure connectivity and economic and trade exchanges between the two countries.
