Two towers of the viaduct were exploded as cannons shot water over the large amount of steel and concrete that weighed about 4,500 tons to prevent the dust from engulfing the city. /VCG Photo

The aging bridge collapsed on Aug. 14 last year in heavy rain, causing dozens of vehicles traveling along it to fall about 50 meters to the ground. /VCG Photo
