The completion of track laying is a key achievement, with the overall progress of Phase II now at 88%. While station construction is almost complete at 99%, the project faces challenges, particularly in densely populated areas like Kalbadevi and Girgaum, where heritage structures and narrow roads have caused delays. The construction has affected 423 residential units and 289 commercial properties, with additional disruption caused by the demolition of 20 land parcels and 30 buildings.

Phase I of the Metro 3 project, covering the Aarey-BKC section, was inaugurated on October 5 and opened for commuters on October 7, with an average daily ridership of 22,000. Once fully operational, Metro 3 will offer interchanges with the suburban train network at Churchgate, CSMT, Mumbai Central, and Mahalaxmi stations, easing travel across Mumbai.
