Less known is the awesome 2 floor museum near the south approach with more models, drawings and photos then you will ever see on the construction of one bridge. The two towers of Sutong are 306 meters high while the total bridge length is 8,206 meters. Construction began in June 2003 and the bridge opened in June 2008. The cost was $1.7 billion dollars.The bridge’s two towers are inverted Y-shaped reinforced concrete structures. Each tower has one connecting girder between its legs. The deck of the bridge is a steel box girder with internal transverse and longitudinal diaphragms, with fairing noses at both sides of the bridge deck. The total width of the deck is approximately 45 yards (41 meters), including the fairing noses.Among other notable achievements, the bridge’s two pylon foundations, each founded on 131 piles, are the largest ever attempted, and the 328-yard (300-meter) bridge pylons are the tallest ever constructed. Additionally, the 631-yard-long (577-meter-long) stayed cables are the longest ever made.Since its opening to traffic in 2008, the bridge has reduced the commute between Suzhou and Nantong from four hours to one hour.This iconic project was selected as the world’s 2010 Outstanding Civil Engineering Achievement by American Society of Civil Engineers (ASCE) in its annual Outstanding Projects and Leaders (OPAL) awards program. In the words of the judges, “The Sutong Bridge pushed the technological frontier of long-span bridge construction.” www.aecom.com
