赞桥梁
你用坚强的脊梁，
迎送着飞驰的车辆。
纵然有巨大冲击，
也总能稳稳地担当。
当狂风呼啸吹来，
你用身躯把它阻挡。
海浪无休止的冲撞，
你付出了多少耐心和体谅。
冬日的严寒，
夏天的骄阳，
你会从容应变，
协调有方。
当地震摇晃大地，
你化成无畏的勇士，
纵然伤痕累累
也能把桥面护卫的安然无恙。
你把根基深深的植入大地，
身驱更加稳固刚強。
你象彩虹一样，
跨过了滚滚大江，
携美丽的身影，
给江河添彩，
为大地增光。
当微风轻轻吹过，
你会兴奋地颤抖
內心里充满欢畅。
我知道你最大的愿望,
不是多少赞扬，
而是要让人们不用摸着石头过河，
也不用船行波浪之上，
用你自己的身驱，
就能把他们平安地送往四面八方。
