Pingtang Bridge Aerial Video the Third Largest Viaduct in the World 鸟瞰赤石大桥 平塘特大桥 Pingtang Guizhou China(1,017) feet high / (310) meters high/1,804 foot span / 550 meter span 2019/With Guizhou having more high bridges then any other region on earth, few might not have noticed the mountainous Chinese Province never really had a giant "viaduct" like the Millau Bridge in France. That will all change in 2019 when the Pingtang Bridge opens as the second largest viaduct in the world with the second tallest bridge structure ever built at 328 meters. Originally called the Caoduhe Bridge after the river it crosses, this gargantuan structure will have two back to back cable stayed spans of 550 meters supported on three of the world's tallest bridge towers measuring 328, 320 and 298 meters. Like many wide river valleys in Guizhou, the first plans of a bridge crossing of the Caodu River revolved around suspension bridge schemes with a main span between 1,100 to 1,400 meters. But unlike most wide river valleys in Guizhou, the terrain in the center of the Caodu valley rose considerably from the river level up to a small ridge or hill midway between the high sides of the canyon. This small hill meant that a tower could be placed in the center of the valley and allow a multi-span cable stayed design to work in a manner not unlike the Chishi Bridge in nearby Hunan Province. With so much attention being paid to the three skyscraping support towers, the designers made considerable effort to give these structures a dynamic sculptural quality that emphasize a slimmer profile with less bulk one might expect from such a large mass of concrete. Also not to be overlooked on the Pingtang to Luodian expressway is the spectacular Daxiaojing Bridge that will have Guizhou's longest arch span of 450 meters when it is completed in 2019.//www.highestbridges.com
