广东虎门二桥是世界最宽的钢箱梁悬索桥,中交二公局承建虎门二桥S1标、S2标两个标段,其中S2标大沙水道桥为主跨径1200米的钢箱梁悬索桥,S1标东涌互通施工需跨越高铁、地铁、高速公路、油气管线等,施工难度极大。

The Second Humen Bridge in Guangdong Province is the widest steel box girder suspension bridge in the world. Two sections of the Second Humen Bridge, S1 and S2, were contracted by CCCC Second Highway Engineering. Among them, S2 of Dasha Aqueduct is a steel box girder suspension bridge with the main span of 1200m, and S1 of Dongyong Interchange spans high-speed railway, subway, expressway and oil and gas pipelines. It is very difficult to construct.
