controlled demolitions

Six seconds of controlled explosions wiped out the remains of the Morandi bridge in the northern Italian city of Genoa on 28 June. The demolition paves the way for the building of a new structure, after the dramatic collapse that killed 43 people in August 2018. Engineers used some 550 kilograms of explosive to tear down two towers of the bridge, as cannons shot water over the 40000 tons of steel and concrete to prevent huge clouds of dust engulfing the city.
