Xi'ninghe Bridge S307 lies in the shadow of the giant Xi'ninghe G4216 Expressway arch bridge with its soaring main span of 510 meters. Among concrete arch spans only the Longtan Tianhu Bridge in Guangxi Province is longer with a span of 600 meters.

Much of the height of the Xi'ninghe S307 beam bridges is hidden beneath 70 meters of reservoir water from the completion of the giant Xiangjiaba Dam across the Yangtze River (Jinsha Jiang) 70 kilometers downstream to the east.

The area is home to around 10 high bridges that have all been partially submerged in the reservoir including the Xi'ninghe G4216 Expressway Bridge, the Xi'ninghe X163 Bridge, the Jinshajiang Nan'an Bridge, the Zhongduhe Expressway Bridge, the Zhongduhe G213 Bridge and the Yangliuba Bridge.
