Sutong Changjiang Highway Bridge
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. 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.
蘇通長江公路大橋（簡稱蘇通大橋）位於中國江蘇省，該橋跨越長江，連接蘇州（常熟）和南通兩座城市。公路總里程32.4千米（含南北端引道），實際跨江的橋樑部分約8200米，總投資約64.5億元。蘇通大橋將由跨江大橋工程和南、北岸接線工程三部分組成，建成後將創造四項世界紀錄：世界跨度最大的斜拉橋，斜拉橋主孔跨度1088米，比日本多多羅大橋還長200米；世界最高橋塔，塔高300.4米，相當於100層樓房的高度；最深基礎，蘇通大橋主墩基礎由131根長約120米、直徑2.5米至2.8米的羣樁組成，在40米水深以下厚達300米的軟土地基上建起來的，是世界上規模最大、人土最深的羣樁基礎；最長拉索，蘇通大橋最長拉索長達580米，爲世界上最長的斜拉索。2003年6月開工，於2007年6月18日提前合龍，2008年5月25日蘇通大橋投入試運行，6月30日正式通車，南通進入上海的一小時都市圈之內，成爲長江三角洲區域經濟的重要組成部分。蘇州大橋的建設，對於完善國家公路網，打通我國東部沿海大通道，促進長江三角洲區域經濟社會的協調發展具有戰略意義。
