The key section (from Shengli Third Road to Gangyao Road) of the Yichang Yiling Yangtze River Bridge extension, built by China First Metallurgical Group, officially opened to traffic

Facing the complex challenge of simultaneously demolishing an existing bridge and constructing a new viaduct in the urban core, the project team independently developed and applied patented technologies such as the "bridge deck main structure demolition device" and the "cut box girder positioning and transfer device," optimizing the demolition sequence and transfer process to achieve seamless integration between old bridge demolition and new structure construction. By deeply utilizing BIM and laser point cloud technology for virtual assembly and intelligent monitoring of steel box girders, the steel material waste rate was reduced from 6% to 4.3%, effectively solving the precision and safety challenges during the simultaneous demolition of the existing bridge and construction of the new one in the urban core area.
