River bridge in SW China with world’s longest main span closes core arch

Aerial shot shows the last arch rib of Hejiang Yangtze River Highway Bridge being hoisted for installation at Hejiang county of Luzhou city, Southwest China’s Sichuan province, on June 29, 2019. On July 3, closure of the main arch of the bridge was successful, with all 40 ribs joined together, marking the completion of the most challenging section of the construction project. Once completed, this flying-swallow-shaped tied-arch bridge with concrete-filled steel pipe, the main span of which is recorded as the longest in the world, will allow north-shore residents to cross the river and get rid of the old ferry-boat transportation.
