2025年12月18日，128辆满载重卡列队从50.5米宽、双向8车道的桥面驶过，长江上最宽 钢箱梁悬索桥——武汉双柳长江大桥进行荷载试验，历时3年建设的湖北省第40座、武汉市 第12座长江大桥即将通车。 桥上车轮滚滚，桥下一侧的"江豚湾"水域，几头长江江豚逐浪嬉戏，成群候鸟觅食栖 息。 2025年12月18日，武汉双柳长江大桥进行主跨斜拉桥荷载试验现场。 双柳长江大桥是国家高速公路网武汉都市圈环线重要组成部分，建成后，武汉新洲区到 鄂州市行车时间大幅缩短，两地居民过江更便捷，武汉都市圈环线将受益。 这里是交通要道，也是生态福地。立项之初，大桥建设环评报告记载着沿线各项生态数 据，一张特意附上的江豚母子图提醒施工要高度重视生态环保。 "大桥选用一跨过江悬索桥方案。"全国工程设计大师、大桥总设计师徐恭义介绍，主桥 桥墩和锚碇均设在两岸无水区，1430米主跨一跨过江。南北引桥和两岸立交接线也充分考虑 防洪环保要求，为避让北岸涨渡湖湿地自然保护区，桥位线路专程绕道近1公里。 2025年12月14日，高空俯瞰双柳长江大桥，一跨过江，"江豚湾"尽收眼底。 中国科学院水生生物研究所科考人员在江豚湾附近展开监测，结果显示， ...

Core Points - The successful installation of the first steel box girder marks a new phase in the construction of the Wuhan Shuangliu Yangtze River Bridge, which is a significant project for the national highway network [1] - The bridge will significantly reduce travel time from Xinzhou to Ezhou from one and a half hours to five minutes, facilitating the integration of the Wuhan metropolitan area [2] Summary by Sections Project Overview - The Wuhan Shuangliu Yangtze River Bridge, part of the G9906 Wuhan metropolitan ring line, spans 35.04 kilometers with a main span of 1430 meters and a width of 50.5 meters, designed for a speed of 120 km/h [1] - It features a dual eight-lane standard and is currently the widest steel box girder suspension bridge on the Yangtze River, referred to as the "first bridge" of Wuhan's "East Gate" [1] Construction Details - The main span consists of 90 girder segments, with the first segment being 13 meters long, 4 meters high, and weighing approximately 298.6 tons [1] - A digital twin system is employed to monitor the stress, deformation, and lifting posture of the cable crane in real-time, ensuring precision control within millimeter levels [1] Economic Impact - The bridge will enhance logistics capabilities by connecting Yangluo International Port to Huahu Airport and the Wuhan National Aerospace Industry Base with Optics Valley, promoting integrated development [2]

Core Viewpoint - The successful installation of the first steel box girder for the Wuhan Shuangliu Yangtze River Bridge marks a significant advancement in the construction of this major infrastructure project, which is part of the national expressway network and aims to enhance regional connectivity and logistics efficiency [1][4][10]. Group 1: Project Overview - The New Port Expressway Wuhan Shuangliu Yangtze River Bridge is a crucial component of the G9906 Wuhan Metropolitan Circle Ring Road, with a total length of 35.04 kilometers [4]. - The main span of the bridge measures 1430 meters and is 50.5 meters wide, designed for a speed of 120 km/h, featuring an eight-lane dual carriageway, making it the widest steel box girder suspension bridge on the Yangtze River [4]. - The main span consists of 90 girder segments, with the first installed segment measuring 13.0 meters in length, 50.5 meters in width, 4 meters in height, and weighing approximately 298.6 tons [4][7]. Group 2: Construction Techniques - The installation process utilized a digital twin system to monitor the stress, deformation, and positioning of the lifting equipment in real-time, ensuring precision control within millimeter levels [7]. - Environmental factors such as wind speed and direction were also monitored during the lifting process to enhance safety and accuracy [7]. Group 3: Economic and Regional Impact - Upon completion, the bridge will significantly reduce travel time from Xinzhou to Ezhou from one and a half hours to just five minutes, facilitating the integration of the Wuhan metropolitan area [10]. - The project will create a fast transport corridor connecting Yangluo International Port to Ezhou Huahu Airport and the Wuhan National Aerospace Industry Base, thereby improving logistics hub functionality and promoting the integrated development of "Optics Valley" and "Star Valley" [10].
