On June 6, the arch bridge of the world's largest span arch bridge - Nandan-Tian'e Xia Lao Expressway Tian'e Longtan Super Bridge's main bridge arch truss achieved high-precision closure. The lateral deviation of the axis is less than 10 mm, and the deviation between the arc line shape and the target line shape is less than 30 mm.
According to reports, the Tian'e Longtan Bridge is located 6 kilometers upstream of the Longtan Dam in Tian'e County, Hechi City, Guangxi, spanning the Hongshui River, with a total length of 2488.55 meters. The concrete arch bridge is the largest span arch bridge in the world under construction. The construction of the bridge has greatly promoted the leap-forward development of the design and construction technology of long-span arch bridges.
