On March 14, with the order of the on-site commander, a 32-meter-long, 900-ton simple support box girder slowly landed on the designated bridge pier of the multi-line bridge at Nanning North Station of the Guinan High-speed Railway, marking the successful completion of the longest multi-line bridge in the entire line of the Guinan high-speed railway, laying the foundation for the full completion of the bridge project in the first half of this year.
