Two jacks help rotate an overpass on Danyang Road in Heze, East China's Shandong province on Nov. 8, 2016. The 24,800-ton overpass rotated counterclockwise 81.67 degrees to cross railway lines and a freight yard to connect with the approach parts. The 2,031-meter overpass was built along the railway lines to reduce interference with running trains. [Photo/Xinhua]
