−	Located about 80 kilometers / 50 miles south of the Yangtze River gorge in China’s mountainous Hubei Province, the Zhijinghe River bridge was the highest arch bridge in the world for several years. Opened on November 28th, 2009 with a deck 294 meters / 965 feet in height, it surpassed the Beipanjiang Railway bridge by 12 meters / 40 feet and West Virginia's New River Gorge bridge by 27 meters / 90 feet. The Baishuijiang Bridge, Najiehe Railway Bridge and India’s Chenab Railway Bridge are also higher. The soaring red span is also impressive for its 430 meter / 1,411 foot length, ranking it among the world’s 25 longest arches.	+	Located about 80 kilometers / 50 miles south of the Yangtze River gorge in China’s mountainous Hubei Province, the Zhijinghe River bridge was the highest arch bridge in the world for several years.

-Located about 50 miles (80 kms) south of the Yangtze River gorge in China’s mountainous Hubei Province, the Zhijinghe River bridge is the highest arch bridge in the world.  Opened on November 28th, 2009 with a deck 965 feet (294 mtrs) in height, it surpassed the Beipanjiang Railway bridge by 40 feet (12 mtrs) and West Virginia's New River Gorge bridge by 90 feet (27 mtrs).  India’s Chenab River bridge will be higher when it opens sometime after 2015 but Zhijinghe will still retain the honor of highest roadway arch since Chenab is a railway bridge.  Zhijinghe is also the world’s highest tunnel to tunnel bridge, a record that will go to the Aizhai suspension bridge in nearby Hunan province in 2012.  The soaring red span is also impressive for its 1,411 foot (430 mtrs) length, ranking it among the world’s ten longest arches.

 The type of steel truss arch used for the Zhijinghe bridge may look common but the Chinese have taken it one step further, developing it into a unique type of structure all its own.  The eight large steel tubes that run along the underside of the Zhijinghe arch were initially hollow.  Once the arch was closed, concrete was pumped into these tubes from the bottom up.  First used by the Chinese in 1990, they have refined and improved the technique and now use it on the majority of their steel arch bridges.  Depending on the length of the span and the width of the bridge, different styles of tubing are used.  For Zhijinghe, they adopted an array of single tubes spaced apart from each other.  Other configurations include dumbbells with two tubes closely connected, a mix of a dumbbell and single tubes such as was done on the Beipanjiang River Railway bridge or a tight cluster of tubes known as “multiple contiguous”.  Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the entire structure.
