中新社江苏常州9月9日电 (记者 朱晓颖)世界最大跨度斜拉桥、最大跨度公铁两用钢桁梁拱桥——常泰长江大桥9日通车。“钢铁巨龙”横跨长江南北，连接起江苏省常州市、泰州市。
江苏省交通工程建设局常泰长江大桥建设指挥部现场常务副指挥长夏鹏飞介绍，大桥跨江段全长10.03公里，南北高速公路接线全长31.972公里；由一座跨主航道的主跨1208米钢桁梁斜拉桥、两座跨专用航道的主跨388米钢桁梁拱桥、一座3×124米的非通航孔钢桁梁桥组成；建设过程中实现了减冲刷减自重台阶型沉井基础、“钢—混”混合结构空间钻石型桥塔、钢箱—核芯混凝土组合索塔锚固结构、温度自适应塔梁纵向约束体系4项世界首创设计。
作为公铁合建双层复合型过江通道，常泰长江大桥的公路部分是如常高速公路(S30)的过江段，上层为双向六车道，向北经泰兴东枢纽连接沪陕高速公路(G40)，向南经常州高新区枢纽连接江宜高速公路(S39)；下层为双向四车道，北接泰州泰兴市六圩港大道，南接常州新北区港区大道。
据悉，大桥通车后，常州市、泰州市两地通行时间将从1小时20分钟缩短至20分钟左右。(完)
