CHANGSHA, Feb. 1 (Xinhua) -- A new bridge over central China's Dongting Lake opened to traffic Thursday, marking the completion of a major east-west trunk line.
The bridge over Dongting Lake is a major part of the highway section in Hunan Province. The two-way six-lane bridge is 2,390 meters long, with a main span of 1,430 meters, making it the longest steel girder suspension bridge in China.
The 3,404 km-long Hangrui Highway links Hangzhou City in east China's Zhejiang Province with Ruili City in southwest China's Yunnan Province.
Dongting Lake, known as "the kidney of the Yangtze River," is the second-largest freshwater lake in China and one of the most important wetlands in China and the world.
