AN OVERVIEW
Mumbai Metro is a Mass Rapid Transit system serving the city on the wider metropolitan region which is being built in 3 different phases over a 15 years period with entire completion supposed by 2025.
Its construction has been consigned to the Mumbai Metropolitan Region Development Authority (MMRDA), in 2004 this emerged with a 146.5 km master plan including multiple lines.
On that time because of some issues, the MMRDA Has only developed metro line-1 from Versova – Andheri East – Ghatkopar.
A new 118 km line was approved, and then-incumbent govt provided the much-needed impetus for the development of 2 tracks in 2015 – Dahisar East – Andheri East & Dahisar East – D.N. Nagar in addition to the Cuffe Parade – BKC – Aarey Colony.
A nodal agency named Maha Mumbai Metro Operations Corporation (MMMOCL) was established in June 2019 for conducting & managing all the Mumbai Metro services on lines which are owned by MMRDA. The MMRDA revealed a plan to 337 km long for Maha Mumbai Metro’s network including ten lines of 17 sections.
