According to the report, 23 people are feared dead after two buses and a car plunged into the Savitri River when an aging bridge on a highway linking the states of Maharashtra and Goa caved on Wednesday.
More than 100 emergency workers in boats, helicopters and on foot scoured the site, looking for survivors and the vehicles.
“We have recovered 18 bodies until now, of which 15 have been identified.
One victim is the driver of a bus,” said Sushma Satpute, sub-divisional magistrate of Raigad district.
Constant rain was hampering search operations.
“It is raining heavily and the river is fast flowing, so it is almost impossible to venture into the water and track where the vehicles are,” Satpute said by phone from the site.
Local police, disaster management personnel, Indian Navy divers and coastguard and Indian Air Force helicopters were involved in the operation.
State authorities have come under attack for the accident, given the lack of maintenance for the 88-year-old bridge, the Hindustan Times newspaper reported.
Maharashtra Chief Minister Devendra Fadnavis has ordered a judicial investigation as well as a safety audit of all old bridges.
