Although the Sancha River is crossed by more spectacular spans both upstream and downstream of the Silahe Bridge, this remote arch crossing is still a delightful little gem hidden in the mountains about 50 kilometers north of Anshun city.

The concrete truss-arch has become a discontinued type of bridge span in China as a number of them developed cracks and other issues that forced either closure or replacement. So far the Silahe Bridge seems to be holding its own with a clean bill of health since its opening in 1990.

The Silahe Bridge deck is about 40 meters above the full reservoir level formed by a downstream dam but is at least 100 meters above the original level of the Sancha River.

In 2023 a higher level bypass beam bridge was built next to the older arch bridge.
