The Tian'e Longtan Bridge in Guangxi, China, has been completed and is now the world's longest steel-reinforced concrete arch bridge. With a main span of 600 meters, it surpasses the Third Ping-Nan Bridge by 25 meters. The bridge was constructed by Guangxi Road and Bridge Engineering Group Co. and is part of the Nandan-to-Tian'e Expressway. It crosses a reservoir over the Hongshuihe River and utilizes a cantilever construction method with stay cables. The bridge's steel skeleton is divided into 44 segments and weighs 8,200 tons. Access to the site was challenging, but upgrades were made to accommodate transportation. The bridge's completion highlights the advancements in bridge construction technology.
