Recently, the right-side 9# pier side span of the main bridge continuous rigid-frame structure of the Nanpanjiang Grand Bridge on the Provincial Highway S11 Shizong–Qiubei Expressway, invested and constructed by Yunnan Communications Investment Group, was successfully closed.

The Nanpanjiang Grand Bridge is a continuous rigid-frame bridge with a length of 948.04 meters and a main pier height of 160 meters. It is a key control project of the Shiqiu Expressway. The right-side 9# pier side-span closure segment is 2 meters long, with a girder height of 3.8 meters. It was constructed using the form traveler bottom form bracket, with the side form using the form traveler side form, and a total of 24.8 cubic meters of concrete was poured. During construction, all participating units exercised strict control over the bridge's geometric accuracy, ambient temperature, closure locking, counterweight balance, concrete quality, monitoring and measurement, and construction technology, forming closed-loop management to ensure the successful closure.
