The Weinan Weihe Grand Bridge (渭南渭河特大桥) is a part of the Zhengzhou–Xi'an High-Speed Railway which connects Zhengzhou and Xi'an, in China. The bridge is 79,732 metres (261,588 ft) (49.5 Miles) long crossing the Wei River twice, as well as many other rivers, highways and railways.^[1] Upon its completion, it was the longest bridge in the world, but surpassed by two new bridges on Beijing–Shanghai High-Speed Railway that completed in 2010.

The bridge was completed in 2008 but the railway line itself did not open until February 6, 2010.^[2][3][4]
