#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 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.
