The Mumbai Metropolitan Region Development Authority (MMRDA) is responsible for developing this line. Know more about the impact of this line and its construction progress in this blog.

How Will Metro Line 4 Benefit People?

The Metro Line 4 will bolster Mumbai’s transport network. It will offer commuters an affordable and faster travel option. 

It takes approximately 60-75 minutes to travel from Wadala to Kasarvadavali. However, the metro reduces the same distance to 30-40 minutes. The fast commute can be quite beneficial to people who commute to their offices on LBS road belt in Mulund, Bhandup, Kanjurmarg, Vikhroli, and beyond. 

This metro’s route intersects traffic-prone areas like LBS road junction in Ghatkopar, LBS road Powai junction, Mulund LBS road, Teen Hath Naka and Ghodbunder Road flyover. 

Metro will prove to be an economical and efficient travel option for daily commuters in these areas, offering fares much lower than cabs.

Metro Line 4 & Line 4A – Planning & History

This 32.3-km metro line will pass through the Eastern Expressway and LBS road, also covering areas of Ghatkopar, Bhandup, Mulund, and Teen Hath Naka in Thane. This metro line 4 will have 32 stations. 

In January 2018, the State Government approved the extension of the metro line from Kasarvadavli to Gaimukh. This 2.7-km extension from Kasarvadavli to Gaimukh will be Metro Line 4A and it will have 2 stations. 

The cost of this Metro Line 4A will be 949 crores.

Prime Minister Narendra Modi laid the foundation stone for Metro Line on 24th December 2016. 

The construction work was awarded through the engineering, procurement, and construction model in April 2018. A joint venture between Reliance Infrastructure and an Italian firm was awarded 3 packages between Kasarvadavali and Wadala worth 1,584 crore. The contract for the other two packages were awarded to a joint venture between Tata Projects Limited and China Harbour Engineering Company. 

In September 2019, the MMRDA awarded 342 crore to J Kumar Infraprojects to build a viaduct and two Metro Line 4A extension stations. 

The Maharashtra Government signed a loan agreement with the German Development Bank to fund the construction of Metro 4 and 4A in November 2020.

Current Status of Metro Line 4 & Line 4A

In November 2022, the MMRDA stated that 45% of the civil work on Line 4A was completed. 

In April 2023, the Green Line 4 project status was 49%. 

December 2025 is the estimated completion date of the Mumbai metro line 4.

Metro Line 4 Impact on Real Estate

The fast connectivity offered by the metro will spike investor’s interest in commercial real estate. LBS road may well become the next commercial hotspot of Mumbai owing to its strategic location. 

There can be a good demand for workplaces like Marathon Millennium, a premium commercial tower on LBS road, Mulund, just 2 minutes away from the upcoming metro station. Millennium caters to businesses of all sizes. It has flexible office spaces from 350 to 10,000 sq ft. If you’re in search of commercial real estate investment in Mumbai, Millenium can be the best bet!

Beyond convenient travel options, the Metro Line 4 will also have a positive influence on the real estate micro markets of Bhandup, Mulund, Kanjurmarg, Thane, Ghodbunder Road and Kapurbawadi. 

All these areas connected by Metro Line 4 are likely to experience increased interest from homebuyers. It may even open up the affordable housing market in the emerging areas of Bhandup and Kanjurmarg. 

Projects like Marathon Neohomes in Bhandup will draw the eyes. It is just 10 minutes away from the metro stations in Bhandup. It offers next-generation smart homes at an affordable price. There are 3 unique configurations – Studio, 1 BHK and 2 BHK, each with a range of sizes.


Metro Line 4 metro is one of the key infrastructure projects in Mumbai. Its completion will be a massive boost to Mumbai’s transportation infrastructure. The development will positively impact property prices and increase demand. If you’re a real estate investor, it would be wise to scout for properties in proximity to metro lines for a better return on investment.
