One of the ten largest viaducts in the world, the herculean Sancha Bridge 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. 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.
