Narendra Modi, the Indian Prime Minister, visited Morbi in his home state of Gujarat to see for himself the site of Sunday’s bridge collapse, which killed 135 people.
The 140-year-old Machchu River bridge collapsed just days after it reopened after repairs.
Divers are still searching for victims’ remains.
Nine people have been arrested, including employees of a company hired to maintain the bridge.
The 230m (754ft) bridge was built during British rule in the 1870s.
According to reports, hundreds of people were on the structure when it collapsed. Some jumped into the water, while others clung to the wreckage.
The swiftly moving water swept away many victims. According to officials, the majority of the victims were women, children, and the elderly.
Following his visit to the scene on Tuesday, Mr Modi’s office stated that he stressed the importance of “conducting a detailed and extensive inquiry,” adding that “the key learnings from the inquiry must be implemented as soon as possible.”
Men were bringing in new beds and fresh linen for the injured patients at the government-run civil hospital, which I visited in the morning.
The townspeople’s lives are slowly returning to normal as stores are reopening and there is street traffic.
But Jhulto Pul, one of the most popular tourist destinations in the town and the location of the tragedy on Sunday, is completely silent.
Only the rescue boats’ purring engines can be heard as they continue to circle the murky river waters in search of any additional bodies.
Wednesday will be a day of mourning in Gujarat.
After concerns were raised regarding whether safety inspections were performed before the bridge was reopened, authorities pledged to conduct a thorough investigation.
The nine people detained, according to the police, are all connected to the Oreva group, the company hired to maintain and run the bridge.
They consist of three security officers, two contractors, two managers, and two ticket clerks. According to senior police officer Ashok Kumar Yadav, they are being looked into for culpable homicide that is not murder.
The company has been charged with numerous offences, including failing to get a fitness certificate from the municipality, among others.
