The construction of Wuhu Yangtze River Bridge started on March 22, 1997; the main span steel girder closure project was completed on May 2, 2000, and the bridge was fully connected; the bridge opened to traffic on September 30, 2000.
The total length of the bridge is 6.5 mi (10.5 km), the main channel is 7195 ft (2193 m) long, and the maximum span is 1024 ft (312 m). The upper road bridge deck is a two-way 4-lane urban arterial road with a design speed of 100 km/h, and the lower railway bridge is a 2-track rail with a design speed of 160 km/h. It cost 4.5 billion yuan (US $680 million ).
History
Before China’s reform and opening up
- In 1917, the famous Chinese statesman Sun Yat-sen put forward the original idea of constructing the Wuhu Yangtze River Bridge.
