Hanoi - The Vietnamese government Thursday announced the results of its investigation into the collapse of a 343-million-dollar bridge last September that killed 54 construction workers and injured 80 others.
The probe concluded an imbalance in the foundation of a temporary buttress was the main cause of the collapse of a section of the 2.7-kilometer Can Tho Bridge spanning Hau River in Vietnam's southern Mekong Delta.
"The imbalanced subsidence of one of the buttresses, the main cause leading to the collapse of the bridge, was as an unforeseen circumstance in regular design," the government said.
