Overview

• Two I-girders toppled from an elevated Phase II viaduct at Manapakkam on June 12, crushing a motorcyclist beneath the estimated 50- to 100-tonne beams.
• CMRL said a temporary A-frame slipped unexpectedly, causing girders erected a week earlier near the L&T head office to fall.
• Emergency crews have cleared debris on Mount-Poonamallee Road and reopened the thoroughfare after hours of gridlock.
• An official investigation by CMRL and its contractors is under way to identify any technical faults or procedural lapses in the girder installation.
• The collapse adds to a spate of metro construction mishaps in Indian cities and raises fresh safety concerns at ongoing Corridor 4 works.
