THANE: A portion of Mumbra bypass collapsed on a house in a chawl near Uday Nagar area on Saturday following heavy downpour in the district.
A fire brigade had reached the site for the rescue operation, however, no casualties and injuries have been reported so far.
Earlier in the day, Mumbai witnessed severe water-logging on the streets after the city received heavy downpour, leading to traffic snarls and flight delays.
The downpour, however, had a limited impact on flight operations at Chhatrapati Shivaji International Airport.
"There are no flight diversions or cancellations yet. The flights have delayed by 15-20 minutes," Mumbai International Airport Pvt Ltd (MIAL) said.
Monsoon has already hit Kerala, Tamil Nadu, Andhra Pradesh and North-East, and will move up north from Maharashtra in the upcoming days.
