Dubu Bridge Number 3
杜步大桥3号桥
Yangshan, Guangdong, China
(312) feet high / (95) meters high
328 foot span / 100 meter span
2009


Dubu Bridge #3 is a four span prestressed concrete beam bridge with a maximum span length of 328 feet (100 mtrs) and a maximum pier height of 266 feet (81 mtrs).

Not to be confused with Dubu Bridges #1 and #2, these three 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 and third Dubu spans during this video taken by a 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.

The under construction northbound route of the newer G107 can be faintly seen to the right of the older G107 road.
