The Sutong Changjiang Highway Bridge ( Sutong Bridge) is a cablestayed bridge that spans the Yangtze River in the People's 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.

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（简称苏通大桥）位于中国江苏省，该桥跨越长江，连接苏州（常熟）和南通两座城市。公路总里程32.4千米（含南北端引道），实际跨江的桥梁部分约8200米，总投资约64.5亿元。苏通大桥将由跨江大桥工程和南、北岸接线工程三部分组成，建成后将创造四项世界纪录：世界跨度最大的斜拉桥，斜拉桥主孔跨度1088米，比日本多多罗大桥还长200米；世界最高桥塔，塔高300.4米，相当于100层楼房的高度；最深基础，苏通大桥主墩基础由131根长约120米、直径2.5米至2.8米的群桩组成，在40米水深以下厚达300米的软土地基上建起来的，是世界上规模最大、人土最深的群桩基础；最长拉索，苏通大桥最长拉索长达580米，为世界上最长的斜拉索。2003年6月开工，于2007年6月18日提前合龙，2008年5月25日苏通大桥投入试运行，6月30日正式通车，南通进入上海的一小时都市圈之内，成为长江三角洲区域经济的重要组成部分。苏州大桥的建设，对于完善国家公路网，打通我国东部沿海大通道，促进长江三角洲区域经济社会的协调发展具有战略意义。
