On October 7, 2024, a 13 km stretch between Aarey JVLR and BKC opened, followed by another 9 km stretch from BKC to Acharya Atre Chowk, Worli
The line currently has an average passenger traffic of 70,000 per day, and there has been anticipation for the opening of the complete stretch, which was earlier expected in August but is now likely to happen in September 2025, depending on trials and certifications
The stations include Science Museum, which comes immediately after Acharya Atre Chowk — the last opened station on the southbound stretch. After Science Museum, the stations are Mahalakshmi Metro, Jagannath Shankarsheth Metro, Grant Road Metro, Girgaon, Kalbadevi, Chhatrapati Shivaji Maharaj Terminus, Hutatma Chowk, Churchgate Metro, Vidhan Bhavan Metro, and Cuffe Parade
