The 33.5 km-long underground Metro 3 route stretches from the super-rich Cuffe Parade area to the business hub of SEEPZ at Andheri. En route, it also provides connectivity between the densely populated residential and commercial areas of the city and the political offices, newly developing business centers, railway stations, and the airport.
