Mexico City will seek an international structural expert to investigate the cause of a May 3 transit overpass collapse that left at least 24 people dead and dozens more injured.
The incident occurred about 10:30 p.m. along a section of Metro Line 12 just beyond the elevated Olivos station. According to eyewitness accounts, one of the structure’s concrete beams collapsed as a Metro train was crossing, sending rail cars plummeting approximately 16 ft onto an underlying highway.
