Steel bridge deck pavement of Changzhou-Taizhou Yangtze River Bridge, a cable-stayed bridge with the world's largest span, was completed in east China's Jiangsu Province on Saturday.
Connecting Changzhou and Taizhou cities in Jiangsu, it is the first cross-river facility combining highway, intercity railway and ordinary roads over the Yangtze River, the world's third longest river.
The total pavement area of the upper and lower steel bridge decks exceeds 250,000 square meters, equivalent to 33 standard football fields.
The bridge sets world records for having the largest span among cable-stayed bridges and the largest span among dual-use road and rail steel truss arch bridge.
"The construction team adopted eight types of pavement structures and systems on different areas to enhance the durability of the pavement, driving comfort, and the stability of the highway and railway layer. This has enabled the application of domestically produced materials in the steel deck paving of super-long-span bridges," said Xia Pengfei, executive deputy commander of the Changzhou-Taizhou Yangtze River Bridge construction command department of Jiangsu Communications Engineering Construction Bureau.
After five years of construction, the bridge boasts a total length of 10.3 kilometers, including 5.3 kilometers of road and rail sections. And it is expected to open to traffic by the end of next April.
