A planned explosion has knocked down the remaining spans and supporting columns of the Italian bridge that collapsed last year, killing 43 people.
The blast in Genoa on Friday morning triggered a huge cloud of dust.
Some 3,500 people who live nearby had been evacuated as a precaution in the hours leading up to the detonation; and sirens sounded a final warning.
Others homes directly under the bridge had been evacuated immediately after the August 14 collapse.
