　　The Second Nanjing Yangtze River Bridge, the longest cable bridge (斜拉桥)in China, has been completed seven months ahead of time and will be open to traffic at the end of this month.

　　The 21.2-kilometre-long project actually is made up of two bridges, with an expressway across the Bagua Island in the Yangtze River connecting(连接)the two. The southernmost of the two bridges, with a span(跨度)of 628 metres, is the longest in China and the third longest in the world. The bridge was designed by the Construction Designing Institute of the Transportation Department of China, and was built by the Hunan Road and Bridge Company. The Begua Bridge was started in July 1997.

　　According to Dai Yongning, vice-mayor of Nanjing and the project leader, the new bridge, with a capacity (容量)to take 60,000 transport per day, was built to lessen the pressure(缓解压力)on the old one. The old bridge was only designed to take 15,000 transport per day, 35,000 less than the actual amount in 1999, and more than 20,000 square metres of the road surface is now damaged on the bridge as a result. “Quality is of great importance in the project.”said Dai. Strong measures have been taken against possible corruption (腐败)during the bridge's construction process, which costs a total investment(投资)of 3 billion yuan ( US $361 million).

　　Key universities in East China, including the southeast, Tongji and Zhejiang universities, together with foreign consultation companies, have been invited to check the project. The half-built bridge was completely undamaged in the disastrous flood of 1998.

　　The Third Nanjing Yangtze River Bridge will probably begin construction this April, immediately after the opening of the Bagua Bridge.
