GENOA, Italy—Italian engineers on Friday blew up the looming remnants of a motorway viaduct in the northern city of Genoa whose collapse last August killed 43 people.
In a few seconds, the remains of the 1.2 km (1,300-yard) elevated road that had connected the port city with southern France fell to the ground with a roar, sending up clouds of cement dust and prompting scattered applause from onlookers.
