For Xi’an’s Belt and Road intermodal hub, a Chinese youth team (avg. 30) mastered the nation’s first ultra-wide asymmetric double swivel bridge. Braving tight rail-side spaces, they innovated technologies, balanced 10,000-ton beams, and completed the swivel in 68 mins—a record. With 4 patents, the project opened ahead of schedule.
