On November 25th, the Huangmaohai Sea-Crossing Passage successfully passed its acceptance inspection, signaling the imminent opening of this key national project in December. Following 18 months of preparation and four years of intensive construction, the passage will become another vital maritime route in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), after the Shenzhen-Zhongshan Link.

The Huangmaohai Sea-Crossing Passage is the first sea-crossing project launched after the release of the Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area and a major project under China's 13th Five-Year Plan. Spanning approximately 31 kilometers, it connects the Hezhou–Gaolan Port Expressway in the east to the Xinhui-Taishan Expressway in the west, where it also intersects with the West Coastal Expressway. The project includes two main bridges: Gaolan Port Bridge and Huangmaohai Bridge. The latter, featuring a triple-tower cable-stayed design, will become the largest triple-tower cable-stayed bridge for road traffic in the world upon completion.

According to Zhu Chao, Director of the Management Center of Huangmaohai Passage, the project achieved multiple technological innovations during its construction. These include the "slim-waist" concrete cable tower design, TY-shaped pier structure, and an integrated vibration and energy dissipation system for the triple-tower cable-stayed bridge. These advancements enhance wind resistance and durability while contributing valuable expertise to the high-quality development of large-scale bridges in Guangdong.

Following inspection, the passage requires final approval from the relevant authorities before opening. Once operational, it will address the limited transportation options between the western coastal areas of Guangdong and the GBA's core regions. The project is expected to extend the GBA's economic influence westward and along coastal regions, driving coordinated development of the regional economy.

大湾区再添“黄金通道”！黄茅海跨海通道通过交工验收

11月25日，黄茅海跨海通道顺利通过交工验收，这标志着这一国家级重点跨海通道工程即将于12月正式通车。历经一年半前期筹备、四年艰苦建设，这条跨海通道将继深中通道之后，成为粤港澳大湾区又一条重要的黄金海上通道。

黄茅海跨海通道是《粤港澳大湾区发展规划纲要》发布后首个开工的跨海通道项目，也是国家“十三五”重大工程。通道全长约31公里，东接鹤港高速，西连新台高速并与西部沿海高速相交，包含高栏港大桥和黄茅海大桥两座主桥。其中，黄茅海大桥采用三塔斜拉桥设计，建成后将成为全球跨径最大的三塔公路斜拉桥。

据黄茅海跨海通道管理中心主任朱超介绍，项目建设中取得了多项技术创新，包括“小蛮腰”造型混凝土索塔、TY型引桥墩身设计，以及三塔斜拉桥综合减振耗能体系。这些突破不仅提升了桥梁的抗风性能和耐久性，也为广东长大桥梁高质量发展积累了宝贵经验。

交工验收通过后，通道仍需行业主管部门核备，待完成后方可通车。届时，这一通道将改变粤西沿海地区与粤港澳大湾区核心区域交通单一的现状，促进大湾区经济向粤西和沿海地区辐射，为区域经济协同发展注入新动力。
