On October 9, in Qingjiao Village, Zhongzhai Township, Liuzhi Special District, Liupanshui City, Guizhou Province, the Liuzhi Bridge on the Nayong-Qinglong Expressway has entered the most complex construction stage of the entire bridge—the upper and lower chords of the open-web section. The bridge builders are carrying out construction in an orderly manner on the 196-meter-high pier main girder. As of now, overall construction progress has reached 70%, and the main structure of the bridge is expected to be completed by the end of 2024.

According to reports, the Liuzhi Bridge is a controlling project of the Nayong-Qinglong Expressway. The bridge has a total length of 2,023.5 meters, a clearance of 315 meters from the bridge deck to the water surface at the valley bottom, a maximum single span of 320 meters, and a maximum pier height of 196 meters. Its main pier height, single span, and bridge length rank first in the world among open-web continuous rigid-frame bridges of the same type, and the five-span prestressed concrete open-web continuous rigid-frame girder structure adopted by the main bridge is the first of its kind at home and abroad.
