The Sidu River Bridge (Chinese: 四渡河特大桥; pinyin: Sìdù Hé Tèdà Qiáo) is a 1,222 m-long (4,009 ft) suspension bridge crossing the valley of the Sidu River near Yesanguan in Badong County of the Hubei Province of the People's Republic of China.

[4] The bridge is part of the new G50 Huyu Expressway that parallels China National Highway 318, an east-west route between Shanghai and Chongqing,[1] crossing the wide belt of mountains that separate the Sichuan Basin from the lowlands of eastern Hubei.

The Yangtze River pierces the same mountain belt 50 km (31 mi) to the north, forming the famous Three Gorges.

The Yiwan Railway, completed in 2010 and running parallel to the highway, has been described as China's most difficult to build and most expensive (per km) rail line.

The rockets carried the pilot cables across on October 6, 2006 and resulted in time and cost savings.
