Puli Bridge
普立特大桥
Pulixiang, Yunnan, China
1,115 feet high / 340 meters high
2,060 foot span / 628 meter span
2015


Puli Bridge will become the highest suspension bridge in Yunnan Province when it opens in 2015. The main span of 628 meters will be unique among China's highest suspension bridges in that it will have a thin, box deck girder instead of the usual truss. The Longjiang Bridge - also under construction in Yunnan Province - will also utilize an aerodynamic box deck girder. The entire deck will require 52 segments of 12 meters in length. The bridge crosses Puli creek just 200 meters before it empties into the spectacular Gexianghe River gorge.

The span is part of the new G56 expressway that will connect the city of Xuanwei, Yunnan with Liupanshui, Guizhou as well as the G76 expressway in Bijie, Guizhou. This entire Yunnan/Guizhou border region is becoming a new hot spot of high Chinese bridges. In addition to Puli they include the Beipanjiang Railway, Beipanjiang 2013, Beipanjiang 2016, Dimuhe, Zongqihe and Yuzuo Bridges.



Puli Bridge Elevation


The official photo and computer rendition above shows how the bridge would look if it crossed over the Gexiang River gorge. The bridge will actually cross the above view 90 degrees adjacent by coming straight from the left side slope and directly towards you. The Puli River is a tributary of the Gexiang and is hidden below the view of the camera.

If the Gexiang River were to be crossed by a suspension bridge it would likely be more then 500 meters high!

In 2011 a series of construction roads were created to access the foundation of one of the bridge towers. Construction of the bridge began in 2012.

Puli Bridge satellite image with bridge and highway drawn in. Note how the bridge crosses the Puli River just before it empties into the Gexiang River that flows off to the right. The Puli River likely tumbles down a waterfall-like cascade for the last 100 meters of descent before it blends into the Gexiang River.
