A section of the embankment of the River Arno in central Florence collapsed on Wednesday morning, sending part of the road and at least 20 parked cars into a newly formed ditch.
The collapse took place very close to the famous Ponte Vecchio, a medieval covered bridge over the Arno.
The hole is about 200m (650ft) in length and 7m (23ft) across.
Firefighters believe the chasm has been created by the failure of a large water pipe beneath the surface.
