Mumbai Metro Line 3: Construction timeline

Twin tunnels of 5.2 metres in diameter each, are being dug at a depth of 20-25 metres below ground. Seventeen tunnel boring machines are being used, to construct these tunnels. A section spanning 1.2 kms, from the Bandra-Kurla Complex to Dharavi stations, will pass under the bed of the Mithi river and an additional stabling line is being constructed for this section of Line 3.

The original deadline for Line 3 was 2016 but owing to various legal disputes and environmental issues arising out of its construction, it is now expected to be completed in 2021. Full-fledged construction activities commenced on May 18, 2017, when officials notified the concerned authorities that any further delay would escalate the cost of the project by as much as Rs 4 crores per day. Line 3 will be implemented in phases and the first phase will connect Aarey Milk Colony to Mumbai airport. This section of the corridor is expected to be opened by December 2021 and the remaining section, up to Cuffe Parade, will open by mid 2022.

 

Mumbai Metro Line 3 connectivity and route

Line 3 will provide commuters connectivity to other metro lines, as well as the suburban railways. Under the original plan, there was no direct connectivity to the airport and commuters would have to exit the metro station, come up to ground level and cross a road on foot, to reach Mumbai airport. However, the MMRCL was directed by former chief minister Devendra Fadnavis to provide direct access from the metro, to the airport and Mumbai Central railway station.

The following are the stations with interchanges on Line 3 of the Mumbai Metro:

  • Churchgate – Western Line
  • CSMT Metro – Central Line, Harbour line, Indian Railways
  • Grant Road – Western Line
  • Mumbai Central Metro – Western Line, Indian Railways
  • Mahalaxmi – Western Line, Monorail
  • Dadar – Western Line, Central Line, Indian Railways
  • BKC – Metro Line 2 (under construction)
  • Domestic Airport – Line 7 (under construction)
  • Sahar Road – Line 7 (under construction)
  • International Airport – Line 7 (under construction)
  • Marol Naka – Line 1 (operational)
  • SEEPZ – Line 6

On February 14, 2019, the MMRCL announced its fifth tunnelling milestone at the Chhatrapati Shivaji Maharaj International Airport (CSMIA)-T2 on Line 3 of the Mumbai Metro. The corridor between CSMIA-T2 station and Aarey Colony will provide access to the Versova-Andheri-Ghatkopar Metro 1 line at Marol Naka and the Swami Samarth Nagar-Jogeshwari-Kanjurmarg-Vikhroli Metro 6 line at Aarey Station. It will also provide some much-needed connectivity between the business hubs of MIDC and SEEPZ, which are not currently connected by Mumbai’s local trains.

On February 21, 2019, it was announced that a sixth tunnelling project had been completed at the Sahar Road metro station. Starting from September 2018, tunnelling of 692 metres had been completed in this critical section of Line 3, with part of it running under the Tansa Water Pipeline. This new section on Line 3 will help connect Sahar Road to the rest of the city.

Impact of the Colaba-Bandra-SEEPZ line on real estate

There is optimism that the development of the metro rail in Mumbai, will bring about a transformation and boost the real estate sector. “Developers’ interest in projects near the metro routes, has been increasing and there is an upward pressure on prices. The micro-markets that are likely to benefit are CBD (central business district), SBD (secondary business district) north and the western and eastern suburbs. Moreover, residential properties in Thane and Navi Mumbai will receive a boost, due to improved connectivity with the commercial hubs in the western suburbs and SBD north,” explains Surabhi Arora, senior associate director, research, Colliers International.

Ashutosh Limaye, head, research and REIS, JLL India said, “Apart from the areas that are adjacent to the metro line, sometimes, the impact of the metro is also felt in nearby locations. The impact is especially profound, when metro stations are located at commercial centres.” It is, hence, wise to invest in a project, where a metro rail is expected to come up in the vicinity, to get good returns, he added.

Tunnel under Mithi River completed

In March 2020, the MMRCL achieved a major milestone, when it finished the tunnelling work on one of the two tunnels passing under the Mithi River. The tunnels are at a depth of 12.5 metres below the river.

Leading PSUs and corporates vie for naming rights of stations

The Mumbai Metro Rail Corporation (MMRC), which is implementing the project, has received 87 expressions of interest (EOIs) to acquire rights to name 18 stations. In all, 28 organisations have expressed their interest in naming rights, with many of them showing interest in multiple stations, MMRC said in a statement, on February 7, 2020. These include large PSUs like LIC, Indian Oil, banking and financial institutions like SBI, Bank of Baroda, UTI, Kotak, IDFC First, HSBC, airlines like Indigo, SpiceJet, and corporates like JSW, GlaxoSmithKline, TimesGroup, Blackstone, Phoenix Mills, Piramal, Oberoi, DB Realty among others. “The BKC station, being the most significant business district in the city, was the most sought-after station with 12 EOIs. Dadar and Airport Terminal 2 stations were joint second, receiving nine EOIs each, followed by Airport Terminal one and CSMT with seven EOIs each,” it said.

Mumbai Metro Line 3 environmental clearance

The construction of Line 3 has been mired by several environmental issues, including the felling of trees and noise pollution complaints. On June 6, 2017, it was reported that over 5,000 trees were proposed to be cut in various areas of south Mumbai. The high court had earlier imposed a stay on the cutting of trees but on May 5, 2017, it vacated its stay and gave a go-ahead to the MMRCL to cut the trees, after observing that a balance needed to be established between development and environment. It is now reported that a total of 5,012 trees will be affected, of which 1,331 will be cut and the remaining 3,681 will re-planted in other parts of the city.

In March 2017, MMRC director Ashwini Bhide had stated that the metro was designed in a way that would minimise the cutting down of trees and that three times more trees would be planted to make up for the loss. She further stated that if all the trees that needed to be cut were saved, it would reduce carbon dioxide in the air by 6,100 kg. However, the metro would help cut CO2 emission by 9.9 million kgs, by significantly reducing the number of vehicles on the road.

The work on Line 3 also ran into trouble, when residents in parts of Churchgate, Cuffe Parade and Mahim, complained that noise pollution norms were being flouted during the construction. The Maharashtra government, on June 4, 2018, told the Bombay High Court that it had recorded the decibel levels at three spots where construction work was underway and had sent a report to the Maharashtra Pollution Control Board (MPCB), for further action. The Bombay High Court, on July 18, 2018, said it was not inclined to allow the MMRCL to carry out construction for the Metro 3 Line in south Mumbai’s Cuffe Parade area at night, until the MPCB submitted its report on noise pollution.

 

Mumbai Metro Line 3 Aarey Colony car-shed

The Mumbai Metro Line 3 project has also come under fire from various quarters, for the proposed car-shed at Aarey Colony, a prime green tract in the city. The plan to build the car shed, has been criticised by NGOs, activists and large sections of the society. Shortly after assuming power, Maharashtra CM Uddhav Thackeray, on November 29, 2019, ordered a stay on the construction work of the metro car-shed. Following this, the state government, on December 11, 2019, announced that it will set-up of a four-member committee, to identify an alternative land for the car-shed.
