The fully underground Metro Line-3, a joint venture of the Centre and State governments, is designed to cater to 1.7 million passengers daily with a frequency of 3-4 minutes, carrying around 2,500 passengers per trip. The project faced numerous challenges, including tunnelling through complex geology, below old buildings, and congested areas. Notable achievements include the first twin-tunnel breakthrough in the country and the use of 17 Tunnel Boring Machines (TBMs) simultaneously. The most difficult task was tunnelling under the Mithi river, which required expertise and advanced technology. The MMRC successfully completed 3 kilometers of tunnelling between BKC and Dharavi, including a 484-meter tunnel beneath the Mithi river. Other challenging areas included tunnelling under the existing Metro line at Marol Naka, Western Express Highway at Santacruz, and the heritage precinct at Hutatma Chowk.
