The Panguan grand bridge, part of the Anshun-Panzhou highway in southwest China's Guizhou, has completed closure. The bridge stretches 2,289.5 meters across a canyon in the Wumeng Mountains. Its tallest pillar? A jaw-dropping 171 meters high -- that's over 50 stories. #Guizhou #China #megabridge #EngineeringMarvel #AmazingChina
