近日，狮子洋通道主桥桥塔高度成功突破300米大关，标志着这一粤港澳大湾区重点跨海工程取得关键性进展。狮子洋通道连接广州市南沙区与东莞市虎门镇，是继港珠澳大桥、深中通道之后又一重大跨海交通基础设施项目。主桥采用双塔单跨悬索桥设计，两座主塔高度均超过300米，建成后将成为世界最高悬索桥桥塔之一。此次桥塔封顶不仅体现了我国在超高层桥梁结构建造领域的技术实力，也为后续主缆架设和钢箱梁吊装奠定了坚实基础。项目预计于2028年建成通车，届时将显著缓解虎门大桥交通压力，提升珠江口东西两岸互联互通水平，进一步推动粤港澳大湾区一体化发展。
Recently, the main tower of the Shiziyang Link has surpassed the 300-meter mark, marking a critical milestone in this major cross-sea infrastructure project in the Guangdong-Hong Kong-Macao Greater Bay Area. The Shiziyang Link connects Nansha District in Guangzhou with Humen Town in Dongguan and represents another significant cross-sea transportation corridor following the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Link. The main bridge features a two-tower, single-span suspension design, with both towers exceeding 300 meters in height—making them among the tallest suspension bridge towers in the world upon completion. This achievement not only demonstrates China’s advanced engineering capabilities in constructing ultra-high bridge structures but also lays a solid foundation for subsequent cable installation and steel box girder erection. The project is expected to open to traffic in 2028, significantly alleviating congestion on the Humen Bridge and enhancing connectivity between the eastern and western shores of the Pearl River Estuary, further accelerating integrated development in the Greater Bay Area.
