Traffic was being slowly restored and firefighters were using water sprinklers to bring the dust levels down around the Apex and Ceyane towers, which had stood on the edge of a busy highway linking India’s most populous state, Uttar Pradesh, to the capital.
Some buildings in the vicinity were covered in white plastic sheets to protect them from debris.
Many users on Twitter believed the decision to blow up the buildings was a stringent anti-corruption measure that would serve as an example and warning to builders and construction businesses.
The blast was predicted to produce about 80,000 tonnes of rubble, the most of which would be used to fill the site and the remainder recycled.
Several households evacuated on Saturday, citing increased pollution and health risks from the large debris.
Sudeep Roy, the owner of a four-room flat in an adjacent low-rise building, said he reserved hotel rooms for the night with family and friends last week.
