本文摘要：Sutong Changjiang Highway Bridge苏通长江公路大桥The Sutong Changjiang Highway Bridge ( Sutong Bridge) is a cablestayed bridge that spans the Yangtze River in the Peoples Republic of China between Nantong and Changshu, a satellite city of Suzhou, in Jiangsu Province. the highway is 32.4 kilometers long. Overall the bridge length is 8,206 metres (26,923 ft) and construction has been estimated to cost about 6. 45 billion yuan RMB. Sutong Bridge can claim four worlds records. The largest main span (1088m) : as far as main span is concerned, Sutong Bridge is 200m longer than that of Tatara Bridge m Japan; the highest pylon ( over 300m) ; the deepest foundation (steel casing depth: 120m) and the longest stayed cable (580m). Construction began in June, 2003 and the bridge was linked up on June 18, 2007, one year ahead of schedule. The bridge was opened to traffic on May 25, 2008 and was officially opened on June 30, 2008. The completion of the bridge makes the commute between Shanghai and Nantong, originally completed through ferry route, shorten to about an hour. It brings Nantong one step closer to becoming an important part of the Yangtze River Delta economic zone, and has further attracted foreign investors into the city. The bridge is also pivotal in the development of poorer northern Jiangsu regions.苏通长江公路大桥（全称苏通大桥）坐落于中国江苏省，该桥横跨长江，相连苏州（苏州）和南通两座城市。

苏通大桥将由横跨江大桥工程和南、北岸接线工程三部分构成，竣工后将建构四项世界纪录：世界跨度仅次于的斜拉桥，斜拉桥主孔跨度1088米，比日本多多罗大桥还宽200米；世界最低桥塔，塔高300.4米，相等于100层楼房的高度；深达基础，苏通大桥主墩基础由131根长大约120米、直径2.5米至2.8米的群桩构成，在40米水深以下厚达300米的软土地基上辟一起的，是世界上规模仅次于、人土深达的群桩基础；最久拉索，苏通大桥最久拉索长达580米，为世界上最久的斜拉索。2003年6月动工，于2007年6月18日提早合龙，2008年5月25日苏通大桥投放试运营，6月30日月通车，南通转入上海的一小时都市圈之内，沦为长江三角洲区域经济的最重要组成部分。

苏州大桥的建设，对于完备国家公路网，切断我国东部沿海大通道，增进长江三角洲区域经济社会的协调发展具备战略意义。
