A red signal at a traffic junction near a foot overbridge (FOB), a major part of which caved in here Thursday evening, proved lucky for a large number of motorists who were waiting for it to turn green.
Without the red signal, the motorists would have passed under the ill-fated bridge near the CSMT railway station, a global heritage site, when a part of it came crashing at around 7.30 pm.
The bridge connected the bustling Chhatrapati Shivaji Maharaj Terminus railway station with the Azad Maidan Police Station.
An eyewitness, who was waiting at the signal, said, "We all were waiting impatiently at the signal as it was red. Before the signal turned green, the bridge came down along with people on it. Had the signal turned green earlier, the situation would have been worse."
