Dubu Bridge #2 is a seven span prestressed beam bridge with a maximum span length of 328 feet (100 mtrs) that curves along the slope of a mountain. Maximum pier height is 302 feet (92 mtrs). The bridge is the second of three tall viaducts on route G107. Nearby Dubu Bridge #1 is even larger with a maximum span length of 410 feet (125 mtrs) and a pier height of 361 feet (110 mtrs) while Dubu #3 has piers as tall as 266 feet (81 mtrs). A long tunnel separates Dubu 1 and 2.


All three of these 2-lane bridges are part of an upgrade to the older route G107 that makes a steep descent into the river valley. The southbound lanes use the older route to climb out of the valley while the northbound lanes cross the 3 large beam bridges as the road descends north into the river valley on a shallower grade.You can see a bit of the first bridge and more of the second during the first two minutes of this video that was taken by a passing bus passenger: http://www.tudou.com/programs/view/LESdFORTExI/

The bridges are located about 8 miles (13 kms) and 10 miles (16 kms) south of Yangshan.
