  •   China’s Hangzhou Bay Bridge, 35.5 kilometers long, connecting Zhengjiadi of Haiyan in the north and Shuiluwan of Chixi in the south, is the longest bridge across the sea in the world today, 11kilometres longer than King Fahd Causeway between Saudi Arabia and Bahrain. It has been listed as the longest cross-sea bridge of the world by China’s World Record Association and the second longest bridge, close second to Lake Pontchartrain Causeway of the United States. The main construction of the Bridge was put under way in 2003 and in 2008 it was open to traffic. The Hangzhou Bay Bridge is the major project based on China’s inde

      The Hangzhou Bay Bridge, a convenient channel across the Hangzhou Bay, is part of the national main route between Shengyang and Haikou and also part of the national highway network (G92) along the Hangzhou Bay. The bridge cuts the length of the road trip from Shanghai to Ningbo by 120 kilometers, thereby main cities in Jiangsu and Zhejiang can be reached by car within 2 hours from the center city Shanghai.

      The Bridge was designed up to the expressway standard with six lanes in two directions, and the design speed of 100 kilometers per hour, the service life of 100 years and the expense of ¥11.8 billion. Two waterway bridges were built with northern one being a diamond-shaped double-cable-plane, double-pylon steel box girder cable-stayed bridge whose main span is up to 448 meters and the tonnage traffic capacity up to 35, 000 tons, and southern one being an A-shaped double-cable-plane single-pylon steel box girder cable-stayed bridge whose main span up to 318 meters and the navigation standard up to 3000 tons. The concept of the landscape design was introduced for the first time in the construction of the Bridge. The landscape designers set up general principals for the Bridge construction by blending the aesthetic concept of West Lake’s Su Causeway sleeping on the ripples, hydrological environment of the Hangzhou Bay and the drivers and passengers’ psychological elements. Generally, the Bridge, being S-shaped, looks beautiful and lively. Viewed from the side, its waterway bridges appear to have the shapes of arches and a three-dimensional appearance, clear rising and falling. At the point 1.7 kilometers to the south of the southern waterway, ie. 14 kilometers form the southern bank of the Hangzhou Bay, there is a platform of 12 thousand square kilometers at sea both for convenient traffic rescue and ideal leisure and tourism.

      The guardrails of the Bridge are decorated with seven colours, and were painted into red, orange, yellow, green, green, blue, purple at an interval of five kilometres from Cixi in Ningbo to Haiyan in Jiaxing.
