The main tower of China's first dual-use suspension bridge was roofed Tuesday in Zhenjiang city, marking a crucial step further before the completion of the project.
The Wufengshan Yangtze River Bridge has a main span of 1092 meters. The upper level is a two-way eight-lane expressway with a designed speed of 100 kilometers per hour.
The lower level is a four-lane high-speed railway with a designed speed of 250 kilometers per hour.
It is the world’s largest dual-use suspension bridge.
In order to ensure the stability of the bridge, a high and low pile group structure is used for the construction of 191-meter main tower to make it the deepest of its kind n China. The depth of the pile varies from 50 meters to 138 meters, equivalent to the height of a 46-storied building.
The Wufengshan Yangtze River Bridge is a controlled project of the Lianyungang-Huai’an-Yangzhou intercity railway, and also an important link on the inter-city transportation hub along the north-south axis of the province. When completed, the train ride from Lianyungang to Nanjing and Shanghai will be slashed to 2 hours and 3 hours respectively.
