一座长江大桥 绿色故事动人（美丽中国）

Core Viewpoint - The Shuangliu Yangtze River Bridge in Wuhan, Hubei, has successfully passed acceptance inspection, emphasizing ecological protection and biodiversity during its construction [4][9]. Group 1: Bridge Design and Construction - The bridge spans 35.043 kilometers and connects Wuhan and Ezhou, crossing the Changdu Lake Wetland Nature Reserve [4]. - The design team modified the bridge plans multiple times to minimize ecological impact, including adding a bend to the bridge alignment, which increased construction costs [5]. - A full-enclosed sound barrier, measuring 400 meters long, 6.38 meters high, and 34 meters wide, was constructed to protect migratory birds, marking a first in Yangtze River bridge construction [5][6]. Group 2: Environmental Protection Measures - The bridge's design avoids underwater construction to protect the habitat of the Yangtze River dolphin, using a single-span steel box girder suspension bridge design [6]. - Construction activities were timed to avoid peak periods of dolphin activity, and all steel box girders were prefabricated and assembled on-site to minimize disruption [6][7]. - A closed environmental concrete mixing station was established to reduce noise and dust during construction, and measures were taken to prevent oil spills from contaminating the river [7][8]. Group 3: Pollution Control Systems - The bridge features drainage systems that automatically identify and manage pollutants, with 25 such systems installed in sensitive areas [9]. - The bridge's completion will significantly reduce travel time between Wuhan and Ezhou from 90 minutes to 5 minutes, supporting regional integration and high-quality development [9].
