Descripción:El puente más alto del mundo se inauguró el mes pasado en China. Está ubicado a 375 metros del suelo, aunque hay un río debajo de la estructura de 1.088 metros de longitud. Antes, en recorrer el valle de este río -ubicado en el distrito Guanling, a unos 1.500 kilómetros de Shangai- se tardaba una hora, y ahora puede hacerse en apenas unos minutos.ás-alto-del-mundo

The Baling River Bridge (Balin He Bridge) (坝陵河大桥) is a suspension bridge in Guanling County in Guizhou Province of China.[1] The bridge spans the Baling River Valley and opened to public traffic on December 23, 2009.[2] The bridge is part of the G60 Shanghai–Kunming Expressway between Kunming and Guiyang and reduced the travel time across the river valley from one hour to four minutes.[3] The suspension span is 1,088 m (3,570 ft) long, and the bridge has a total length of 2,237 m (7,339 ft). It is also one of the world's highest bridges with 375 m (1,230 ft) of clearance above the river.[4][5]

Balinghe River Bridge


Guanling, Guizhou, China

1,214 feet high / 370 meters high

3,570 foot span / 1,088 meter span


With a height of 1,214 feet (370 mtrs) from deck to water, the Balinghe River bridge is the second highest bridge in China and the 3rd highest road bridge in the world. Located near the town of Guanling about a third of the way along the 300 mile (483 km) Guiyang to Kunming Highway in China’s mountainous Guizhou Province, Balinghe is one of two super high suspension bridges along the 4-lane route.

Of the world’s 300 or so highest bridges, Balinghe is unique for having the 2nd longest span length with a distance between towers of 3,570 feet (1088 mtrs) - nearly as long as the Golden Gate bridge! The gap is so great the bridge appears to be floating among the clouds as it connects two mountain ranges. Balinghe is one of 4 high Chinese suspension bridges with extremely long spans. The other three being the Siduhe, Aizhai and Beipanjiang 2009 highway bridges. Prior to these spans, the longest bridge of any notable height was the New River Gorge bridge in West Virginia with an arch span of 1,700 feet (518 mtrs). In 2012 the world's longest span high level bridge record will go to China's Aizhai Bridge with a span of 3,858 feet (1,176 mtrs).

The design of Balinghe is similar to some of China’s other long span suspension bridges that cross the lower end of the Yangtze but with a few subtle changes. The most notable of these is the sleek, trapezoid-like shape of the tower openings and the lighter, less bulky triangular shaped east anchorage. The saddle covers are also modern looking and somewhat reminiscent of the Tsing Ma bridge in Hong Kong. About the only element of the bridge that might be considered ordinary is the extremely deep 4-story high stiffening truss below the road deck which harks back to the classic, post-Tacoma U.S. suspension bridges of the 1950s like the Mackinac bridge in Michigan.

While a suspension bridge might seem to be a no-brainer for such a long, high crossing, Chinese engineers did design a concrete beam viaduct and several multi-span cable stayed bridges. With a central tower rising nearly 1,500 feet (457 mtrs), any one of the cable stayed schemes would have surpassed France’s Millau bridge as the world’s tallest. With so much concrete required for so many tall piers, there simply was not enough natural sand found at or near the bridge site and man-made sand is not suitable for concrete mixing. If natural sand had been transported from a far city, the cost of the project would have sky rocketed.

Balinghe bridge is located in a hot spot of high Chinese bridges and is less than 100 miles (161 km) from 4 others in the region, including the three great crossings of the Beipanjiang river. The closest of the Beipanjiang bridges is on the same highway as Balinghe about 20 miles (32 km) east and is among the world’s ten highest bridges at 1,080 feet (330 mtrs). Also be sure to visit nearby Huangguoshu waterfalls, one of the largest in China with a drop of 243 feet (74 mtrs). Of all of China’s provinces, Guizhou (pronounced Gooey-Joe) will probably have the greatest number of high bridges as there are still several major and minor highways to be constructed in the next decade.

If you are wondering why Balinghe bridge has the unusual span length of 1088 meters, it relates to the luck the Chinese associate with the number 8 which sounds like the Mandarin word for “prosperity”. It was no coincidence that the Beijing Olympics began at 8:08 pm on the eighth day of the eighth month of 2008. Several other high suspension bridges also have metric span lengths that end with the number 8 including the Beipanjiang 2003 bridge with a span of 388 meters and the Xixi suspension bridge with a span of 338 meters. There is, however, no superstition related to the number 13, so watch out or you may find yourself on the 13th floor of a Chinese hotel!
