Labajin Bridge
Yingjing, Sichuan, China
750 feet high / 229 meters high
656 foot span / 200 meter span

One of the ten largest viaducts in the world, the huge new Labajin Bridge is a spectacular new addition to a north-south highway that will finally connect Chengdu with Kunming in China's western province of Sichuan. The most amazing part of this bridge is pier 10 which rises 600 feet (182.6 mtrs) from the foundation. This is the highest bridge pier ever built in China and ranks 4th in the world after Millau in France and the San Marcos and El Carrizo bridges in Mexico that are also due for completion in 2012. Unlike other big piers in China, the tallest piers on the Labajin Bridge were built with four steel corner columns that were filled with concrete and are connected by concrete slabs to form a hollow box structure. Pier 10 contains 16 levels of boxes that will support the ends of the two largest spans of 656 feet (200 mtrs). This unique type of pier has never been done before. This is grand scale bridge building of the tallest order and the highway planners have wisely decided to build a tourist parking area that will allow people to take in a view of the bridge and ravine.
