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].
