It is an eight-tower cable-stayed bridge, which constitutes the word "mountain" in the north of Shanxi, meaning the gateway to and from Shanxi. Its completion is an important milestone in the history of traffic science and technology innovation in Shanxi Province. This bridge is the only bridge project that won the Luban Award (National Quality Project), the highest prize in China in 2009.

The bridge entered the site in April 2004 and was completed and opened to traffic on February 28, 2006. It is a controlled project of Hou Yu Expressway with loan from Asian Development Bank.
