Nearly 14 months after the Morandi viaduct collapsed in Genoa, Italy, killing 43 people, crews placed the first section of a 1,067-meter-long, 19-span steel and concrete replacement structure.

The 500-tonne deck spine of the first 50-m-long steel box girder deck span was raised some 50 m above ground by the PERGENOVA joint venture of Salini Impregilo and a unit of a state-controlled shipbuilder.

Locally-based architect Renzo Piano designed the $220-million viaduct.
