The death toll in the collapse of a overpass under construction in the Indian city of Kolkata rose to 23 on Friday, after rescuers worked through the night with cranes and jackhammers to clear huge slabs of steel and concrete.
Ninety people were saved after a 100-meter (110-yard) length of the overpass broke off at one end and slammed into pedestrians and vehicles below on a road through a busy commercial district near Girish Park in the eastern city.
“Many of the people rescued have been seriously injured,” Police Commissioner Ajay Tyagi said. “Many could still be buried below the debris.”
Television channels broadcast images of a street scene with two autorickshaws and a crowd of people suddenly obliterated by a mass of falling concrete that narrowly missed cars crawling in a traffic jam.
Chief Minister Mamata Banerjee, whose center-left party is seeking re-election in the state of West Bengal next month, rushed to the scene on Thursday.
Banerjee, 61, said those responsible for the disaster would not be spared and blamed the previous state government that had awarded the overpass contract in 2007.
Yet she herself faces questions about a construction project that has been plagued by delays and safety fears under her rule.
A newspaper reported last November that Banerjee wanted the overpass – already five years overdue – to be completed by February. Project engineers expressed concerns over whether this would be possible, the Telegraph newspaper said at the time.
The disaster could play a role in the West Bengal election, one of five being held this month that will give an interim verdict on Prime Minister Narendra Modi’s nearly two years in power.
Indian company IVRCL was building the 2-km (1.2-mile) Vivekananda Road overpass, according to its web site. Its shares closed down 5 percent on Thursday.
A senior IVRCL manager has drawn national condemnation for calling the disaster an “act of God”.
“We did not use any inferior quality material and we will cooperate with the investigators,” director of operations, A.G.K. Murthy said on Thursday in Hyderabad where the firm is based. “We are in a state of shock.”
Rescue operations were slow to get under way at first, with nearby residents forming crowds several deep as they tried to help trapped people.
But three cranes working overnight managed to clear some of the wreckage and free access to vehicles with people still believed to be trapped inside.
Getting survivors to hospital was complicated by the lack of access for ambulances to the overpass, which is crowded by buildings on either side. Safety standards were lax, witnesses said.
“Every night, hundreds of laborers would build the flyover and they would cook and sleep near the site by day,” said Ravindra Kumar Gupta, a grocer, who pulled out six bodies, together with his friends.
“The government wanted to complete the flyover before the elections and the laborers were working on a tight deadline … Maybe the hasty construction led to the collapse.”
