A dramatic new bridge to replace a historical span nears completion.

A 525-ft-long sliding girder, originally built for a Hong Kong project, will place around 1,000 concrete elements of a 2.1-mile viaduct for a new high-speed railroad. 

The 6th Street Viaduct replacement project in Los Angeles has concluded the hanger installation of the first span and the removal of the falsework underneath, says COWI, an engineering consulting group.

Soil contamination prompted construction of a 7-km-long extension of Cairo Metro’s Line 3 on a viaduct instead of below ground, as first planned.

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.

As the California High Speed Rail Authority executes multiple contracts for California’s $62.1-billion high-speed-rail line, crews are making headway on the initial 100 miles of track.
