Mumbai's first underground metro line is open after delays and controversy. This Saturday, Prime Minister Narendra Modi will open the 12.5 kilometre Aarey-BKC metro line's first phase. The new metro line would cut travel time from Aarey to BKC to 22.30 minutes, down from an hour.

Mumbai Metro 1, which serves Versova-Andheri-Ghatkopar, reached 5 lakh daily ridership. The corridor has never had such a high number on a weekday in its 10 years. Ridership increased due to Metro expansion and good weather.

The Mumbai Metropolitan Region Development Authority (MMRDA) is likely to open the 20 km-long stretches of the Yellow and Red metro lines of the Mumbai Metro in October 2021. The stretch will provide the people access to 18 stations in total.
