One of the 25 largest viaducts in the world, the herculean Sanchahe Bridge Xiarong is one of many high beam spans on the G76 expressway, the world's greatest high bridge highway. The Sancha River is the southern fork of the great Wujiang river, the longest and most famous in Guizhou Province. To get across this spacious valley 30 kilometers west of Guiyang city, the engineers went with an arrangement of three central spans of 230 meters each with many approach spans of 40 and 30 meters. The 4-lane structure is 24.5 meters wide with solid piers as tall as 135 meters. Approach spans bring the total length to 1560 meters.

The beam is 12 meters wide with a depth of 14.5 meters over the piers and 4.5 meters at midspan.
