220/G3

在安徽省铜陵市， G3铜陵长江公铁大桥的施工正在全速推进。这是世界首座千米级双层斜拉—悬索协作体系大桥。这条在高空中搭建起的“空中走廊”横跨长江两岸，工人在这条高空“猫道”上穿梭作业、运送物资。记者登上220米高的塔顶施工层，跟随工人一同行走在江面上的高空镂空网道，俯瞰江面，同施工人员、技术专家一起，了解中国公铁大桥的施工工艺。 In Tongling City, Anhui Province, the construction of the G3 Tongling Yangtze River Highway-Rail Bridge is progressing at full speed. This is the world's first kilometer-level double-layer cable-stayed-suspension cooperative system bridge. This “air corridor“ built in the sky spans both sides of the Yangtze River. Workers shuttle and transport supplies on this high-altitude “catwalk“. The reporter climbed to the construction level on the top of the 220-meter-high tower, followed the workers on the high-altitude hollow network on the river, overlooked the river, and learned about the construction technology of China's highway-rail bridge with construction workers and technical experts. 登上220米高空中走廊，探访世界首座双层斜拉—悬索协作体系大桥/中国安徽G3铜陵长江公铁大桥施工现场
