The First Steel Box Girder of the Huangmao Sea Channel Was Erected!

#TheGreatBeautyofGuangdong The construction of the Huangmao Sea Channel, a key project in the Guangdong-Hong Kong-Macao Greater Bay area, has touched another milestone. On June 19, after nearly 4 hours of positioning and connection, the first steel box girder of the Gaolan Port Bridge, a part of the project, was successfully erected, marking the transition of the project to the upper structure construction.

The Gaolan Port Bridge is a cable-stayed bridge with a main span of 700 meters and a total length of 1416 meters. Its main girder consists of two steel box girders. The total weight of the steel structure is approximately 38,000 tons, equivalent to about 90% weight of the Bird's Nest, The Beijing National Stadium. The weight of the first erected steel box girder is about 245 tons, which is in a section without cables on the support tower of the Gaolan Port Bridge.
