Third Nanjing Yangtze Bridge
Location in China

The Third Nanjing Yangtze Bridge is the first cable-stayed bridge located in Nanjing, China.[1] It is the third crossing of the Yangtze River at Nanjing. The cable-stayed portion is just a part of the 4.7 kilometers of the complete bridge. Constructed in slightly more than two years at a cost of $490 million, this bridge features dual 215 meters towers. The main span measures 648 meters. When it was completed in 2005 it was the third longest cable stayed span in the world.[2] It still ranks among the top 20. The bridge carries the G42 Shanghai–Chengdu Expressway and the G2501 Nanjing Ring Expressway

Structure

The deck superstructure is an orthotropic box girder 3.2 m deep and 37.5 wide that accommodates three lanes of traffic in each direction. Also the bridge has a center lane used in case of emergency. The deck is supported by 168 stay cables. Each cable is formed by 109 to 241 wires 7 mm in diameter and 215 m in height.[3]

Funding

The bridge was financed by a joint venture of Chinese public-sector and corporate entities. China's Highway Planning and Design Institute, part of the Ministry of Communications, led the design team.
