The lower third of the Xisujiaohe Bridge is hidden below a portion of the Jinshajiang reservoir that was formed by the giant Xiluodu Dam. The 565 meter long Xisujiaohe Bridge has a span configuration of 3x30 +380 +3x30 meters with a main arch span of 350 meters. The deck of the Xisujiaohe Bridge is 195 meters above the full reservoir level that was formed by the construction of the Xiluodu Dam.
