Mumbai Metro Line - 3 (MML - 3) is one of such key projects to improve the transportation scenario in the financial capital of India i.e. Mumbai. MML-3 project - a 33.5Km. long corridor running along Colaba-Bandra-SEEPZ, envisages to decongest the traffic situation in Greater Mumbai. Mumbai Metro Rail Corporation Limited (MMRC) is the nodal agency responsible for the implementation of Mumbai Metro Line–3(MML-3) project. It has been constituted as a JV of the Govt. of India(GOI) and the Government of Maharashtra(GOM) on 50:50 sharing basis. It aims to provide a Mass Rapid Transit System that would supplement the inadequate suburban railway system of Mumbai by bringing metro closer to the doorsteps of the people. With full-scale operations of MML-3, the city would witness significant reduction in traffic volumes and the local transit facility would get a boost. The MML-3 would bring multiple benefits such as comfortable Air conditioned travel for more than 16 lakh commuters daily, reduction in travel time, reduction in air & noise pollution, improving safety & security of the citizens etc. Upon completion, this fully underground corridor with 27 stations would connect Six business districts, 30 educational institutes, 30 recreational facilities and domestic as well as international airport terminals. It will have five interchange points for suburban railway and one each for Monorail and ‘Versova-Andheri-Ghatkopar’ Metro-1. MML-3 has been envisioned to be the modern transport of the 21st century. State-of-the-art technologies would be harnessed during the construction of the project to ensure protection to existing building structures. To ensure no trespassing on tracks, the stations would be provided with Platform Screen Doors. The stations would also be facilitated with automatic fare collection machines for contactless revenue collection.
