The Luojiaohe suspension bridge is one of many high bridges along the Guiyang to Bijie highway in China’s Guizhou Province. The road is best described as a museum of high Chinese bridges that also includes Liuguanghe, the highest beam bridge on earth. This 100 mile (161 km) stretch of 2-lane highway also contains a sister suspension bridge to Luojiaohe that is 715 feet (218 mtr) high as well as another concrete beam bridge 600 feet (183 mtr) high and two arches, 380 (116 mtr) and 360 feet (110 mtrs) high. Outside of China, there is no other 100 mile (161 km) stretch of 2-lane highway to have so many high bridges.

The Luojiaohe bridge was one of 4 medium sized suspension bridges that were designed and built in the same time period by the Major Bridge Reconnaissance Design Institute in Wuhan, Hubei, China. The bridges all share common traits including an extremely thin 2 foot (.6 mtr) thick prestressed concrete slab deck and cable suspenders just 16 feet (5 mtrs) apart. Since all 4 bridges were of similar length and in similar gorge settings, it was economical and efficient to design them at the same time. The other 3 include the Beipanjiang (2003), Azhihe and Xixi bridges. All four are among the world’s 60 highest bridges. Xixi is also on the Gui-Bi highway just a few miles (kilometers) east of Luojiaohe bridge.

When it was completed, Luojiaohe was a full 600 feet (183 meters) above the Luo Jiao River. The construction of a dam downstream of the river has created a reservoir under the bridge, reducing its height to 480 feet (146 meters) at full pool level. The gorge itself is most spectacular on the west side where it drops vertically to the water for nearly its entire height.

落脚河悬索桥是中国贵州省的交通干线贵毕公路上的众多高桥之一。形容这条公路干线的最好的词汇就是“中国高桥博物馆”,其上还有着世界最高的梁桥六广河大桥。这桥100英里(161公里)长的2车道公路上,还有着一座落脚河大桥的183米高的“姊妹”悬索桥,以及另一座183米高的混凝土拱桥和两座分别高116米和110米高的拱桥。在中国之外,地球上在没有任何一条100英里(161公里)长的公路线上有着如此多的高桥了。

落脚河大桥是同一时期设计、建成的四座中等跨径的悬索桥之一,由位于中国湖北武汉的中铁大桥局勘测设计院设计完成。这四座桥有一些共同特点,例如,桥面相当薄,仅为合0.6米厚的预应力混凝土桥面板,主缆吊杆的间距仅有5米。因为这四座桥桥长相近、而且桥址的峡谷环境也相似,所以一次性设计四座桥是比较经济和高效的,另三座桥分别为2003年建成的北盘江大桥(关兴公路上)、阿志河大桥和西溪大桥。这四座大桥都在世界前50最高的大桥范围之内。西溪大桥也是在贵毕公路之上,位于落脚河大桥以东仅仅数英里(公里)位置处。

在其建成之时,大桥正好183米高架于落脚河之上。由于河流下游建成了一座大坝,桥下就形成了一个水库,使得大桥在水库满水位之时高度仅有146米。峡谷本身在西侧悬崖亦十分险峻壮观,峭壁自顶而下直插入水。

LuojiaoheGuibiAccidents.jpg

The Luojiaohe Bridge parking area has become a storage yard for the many cars that have been involved in head on collisions. The Gui-bi highway has become incredibly dangerous with only 2 lanes and no way to pass slow moving trucks without going into oncoming traffic. All Chinese highways should have a breakdown lane to allow passing on the right (yes this is ok to do in China) or make them all 4 lane divided highways as they have been doing since the Gui-Bi opened in 2001. In the meantime the Gui-bi will continue to be a horribly dangerous and often slow highway that should be avoided if possible. Image by Eric Sakowski / HighestBridges.com
