Explosives were attached to the legs and body of the bridge. Thousands of residents were evacuated before two large towers consisting of about 4,500 tonnes of concrete and steel were brought down. Roads within a 300m (984ft) radius of the demolition site were also closed. In about eight seconds the towers were gone.

Italy’s deputy prime ministers Matteo Salvini and Luigi Di Maio joined onlookers in Genoa for the event. It was also broadcast live on Italian TV. Built in the 1960s, the Morandi Bridge was a vital link of the A10 highway that connects northwestern Italy to France, across the Polcevera river in central Genoa. It was one of the busiest bridges in the country. The demolition of towers 10 and 11 on Morandi bridge took place 37 minutes late because officials were concerned that one elderly resident had refused to leave. Such a bridge is normally designed to last for at least 100 years. But following the 2018 tragedy, it emerged that the steel rods suspending the 1.2km bridge had been slowly decaying over decades and were badly damaged by the sea air. Italian architect Renzo Piano agreed to oversee the construction of a replacement bridge, expected to be Europe’s most expensive.
