Metro 3 has faced numerous delays due to a variety of reasons, including funding challenges, land acquisition issues, and legal battles over environmental concerns. However, with the project nearing completion, authorities are keen on launching the first phase before the assembly polls as part of the government's broader infrastructure development efforts. The metro line will cover 33.5 kilometers and connect key areas such as Colaba, Worli, Dadar, and Bandra, ultimately terminating at SEEPZ, a major business hub. This route will directly serve dense commercial and residential zones, alleviating the pressure on existing road and rail networks.

The metro is expected to be a boon for daily commuters, cutting down travel time between the southern and northern parts of Mumbai by nearly half. It will feature fully air-conditioned trains and modernized stations, equipped with advanced ticketing systems, escalators, and elevators. Additionally, Metro 3 will connect with other metro lines and suburban train systems, providing seamless interconnectivity for passengers traveling across the city.

Environmental concerns, particularly regarding the cutting of trees in Aarey Forest for the metro depot, had slowed the project. However, with revised plans and promises of green initiatives, such as compensatory afforestation, the project has resumed full pace. Authorities are pushing to complete critical stations and trial runs before the election dates are announced.

Once operational, Metro 3 is expected to not only decongest traffic but also reduce pollution levels by encouraging more people to shift from private vehicles to public transport.
