Here are the top 10 updates on Andheri bridge collapse
The 40-year-old foot overbridge crumbled around 7.30 am, ripping off overhead wires and blocking train services on one of three main railway lines into the city. Traffic at the bridge was stopped and trains, which are Mumbai's lifeline, were hit.
Railway Minister Piyush Goyal has ordered an inquiry and asked for a report within 15 days. The Andheri bridge, built in 1971, had a "design flaw", said the minister.
Commenting on the bridge collapse nine months after the Elphinstone Bridge collapse after which 23 were killed in a stampede, the minister said 445 such bridges will be assessed in a safety audit by an IIT director.
According to Mr Goyal, around 700 railway workers are at work, trying to fix the wires and restore train services.
Congress president Rahul Gandhi was among those who tweeted, commenting that civic governance has "collapsed". He posted: "The streets are flooded, citizens stranded, bridges collapsing..... Civic governance has collapsed. My thoughts are with the citizens of Mumbai. Stay safe!"
Heavy rain delayed flights and schools and colleges in several parts of the city declared a holiday. Many students also couldn't make it to exams.
Mumbai's famous tiffin carriers 'Dabbawalas' also expressed their inability to operate as the train services were stopped in that part of the city.
Jet Airways, India's biggest private airline, announced a waiver on penalties for changing flights and refunds for passengers flying out of Mumbai.
Prominent residents of Mumbai took to social media to express their anger and frustration. "Andheri bridge collapse is yet another reminder of how pathetic Mumbai's infrastructure is. For a city that gives so much to the exchequer, we deserve better, if not best. #shame," tweeted actor-filmmaker Farhan Akhtar.
The Meteorological department has predicted heavy rains in Mumbai and adjoining areas in the next 24 hours. The rain caused waterlogging in the low-lying areas of the city.
