Sidu River Bridge by CCSHCC Second Highway Consultants Company, Ltd. and cost 720 million yuan (around €90 million).[1] It was opened to traffic on November 15, 2009, and became the bridge with the highest span in the world[2][3] until 2016, when the Duge Bridge was inaugurated, with a span of 564 m high, also in China.[4]​.

The bridge is part of the new G50 Huyu Expressway parallel to China's National G318, an east-west route between Shanghai and Chengdu, crossing the wide belt of mountains separating the Sichuan Basin from the eastern Hubei lowlands. The Yangtze River runs through the same mountain range about 50 km to the north, forming the famous Three Gorges. The Yichang-Wanzhou Railway, completed in 2010 and running parallel to the expressway, has been described as the most difficult and most expensive railway line to build in all of China.[5]

The bridge rises 496 m above the valley of the Sidu River (a left tributary of the Qingjiang River), and surpassed the Royal Gorge Bridge and the Beipan Guanxing Bridge as the highest bridge in the world.[3]
