Built on steep mountainsides, getting around Wushan County has never been easy.⁣ ⁣ To meet residents’ needs, the county constructed the world’s longest outdoor escalator, stretching about 905 meters.⁣ ⁣ Climbing slopes with an average gradient of 40 degrees, where machinery struggled to operate, large amounts of materials were carried up step by step by workers to make it possible.⁣ ⁣ Put into trial operation this February, it has already become a vital part of the city’s transport system.⁣ ⁣ #Chongqing #Wushan #Engineering #Infrastructure #MegaProject
