The Mumbai Metropolitan Region Development Authority (MMRDA) has claimed that it has completed erecting 73 per cent of the total number of pillars required for six under-construction lines.
According to data provided by MMRDA, it has completed work on 3,603 pillars of the total 4,929 to be constructed.
| Project | Pillar Completion Status | Total Pillars | Completed Pillars |
|---|---|---|---|
| Line 2B (DN Nagar to Mandale | 50.7% | 1,109 | 614 |
| Line 4 (Wadala to Kasar Vadavali) | 55% | 1,476 | 973 |
| – Line 4A | 221 | 143 | |
| Line 5 (Thane to Bhiwandi) | 78.4% | 464 | 440 |
| Line 6 (Swami Samartha Nagar to Vikhroli) | 70.75% | 769 | 657 |
| Line 9 (Dahisar to Mira Bhayandar) | 61.28% | 900 | 776 |
However, Mumbai Metro still has a long way to go before these lines are ready and commissioned.

According to MMRDA, the main focus is on the casting and erection of heavy-weight precast elements, such as pier caps, U-girders, and I-girders. These precast elements are produced at different casting yards, transported to the location, and erected using cranes with capacities ranging from 350 MT to 500 MT.
Transportation and erection activities of these precast elements are carried out at night to minimize disruption to public traffic and ensure safety.
No target dates for completion have been provided by MMRDA for any of these projects. Land acquisition issues continue to bog down construction of the crucial maintenance depots for trains on Line 4, Line 5 and Line 9. Rolling stock manufacturing contracts are also yet to be awarded for Line 4/4A, 5 and 6. This makes it unlikely that any of these lines will become operational before 2026.
“MMRDA is prioritizing the completion of all Mumbai Metro corridors as quickly as possible. The recently inaugurated Metro corridors of Line 2A and 7 are providing relief to lakhs of commuters, contributing to reduced highway traffic and pollution, The MMRDA is currently in the process of appointing a consultant to obtain various permissions for Metro Line 10 between Gaimukh and Shivaji Chowk (Mira Road). Additionally, a general consultant has been appointed, and the tendering process for the civil works is underway for Metro Line 12 (Kalyan Taloja).” said Dr Sanjay Mukherjee, IAS, Metropolitan Commissioner, MMRDA.
