en.Wedoany.com Reported - Recently, the pedestrian bridge projects over the north and south canals at Longhu Financial Island in Zhengdong New District, Zhengzhou City, Henan Province, undertaken by China Railway First Group Co., Ltd., successfully passed completion acceptance and are now officially ready for use. The south bridge has a total length of 122 meters, and the north bridge has a total length of 85 meters. Both are designed as single-span shallow arch bridges with variable cross-section steel box girders, featuring a remarkably low rise-to-span ratio of 1/32.
The project commenced on March 1, 2025, with the construction site located over the north and south canals of Longhu Financial Island in Zhengzhou. Facing multiple challenges such as the narrow site in the core area, restricted machinery access, high-altitude hoisting across the canal, and construction during the flood season, the project team from China Railway First Group established a construction plan of "segmented prefabrication in the factory + on-site assembly using a floating crane." The steel box girders were erected using a method of "transverse block division and longitudinal segmentation," with beam segments hoisted onto temporary supports by a floating crane vessel. Multiple rounds of plan simulations and trial hoisting drills were conducted before each high-altitude lift.
Upon completion of the two bridges, pedestrian flow in the north-south direction of the Financial Island no longer needs to detour, significantly reducing the time required to cross the canal on foot and correspondingly improving the operational efficiency of the municipal system. These pedestrian bridges are an important part of the slow-traffic network of Longhu Financial Island, which is another national-level financial center area following Beijing Financial Street, Shanghai Lujiazui, and Shenzhen Qianhai.
