Amid resounding cheers, the final tunnel along the Xi'an-Ankang High-Speed Railway (XKA HSR)—the Qinling Jiutianshan Tunnel—was successfully holed through on May 13. This milestone marks the complete breakthrough of all 20 tunnels along the route.

Currently, construction is in full swing across the project, with progress rapidly advancing on its 33 bridges, 10 subgrade sections, and six newly built station buildings. The XKA HSR is now proceeding at full throttle toward its targeted completion date. (Photo by Yang Qiyue, Wang Shaohua/China Youth Daily)
