The Maharashtra government has approved a loan guarantee for six Metro projects led by the Mumbai Metropolitan Region Development Authority (MMRDA), enabling continued funding from international financial institutions for ongoing construction. The proposal was sanctioned in a Cabinet meeting chaired by the Chief Minister.

The approved corridors include Metro Lines 5 (Thane–Bhiwandi–Kalyan), 6 (Swami Samarth Nagar–Vikhroli), 9 (Dahisar East–Mira Bhayandar), 10 (Gaimukh–Shivaji Chowk, Mira Road), 11 (Wadala–CSMT), and the 3.3-km underground extension of Metro Line 7 from Gundavali to the international airport via Marol. These projects, involving both elevated and underground sections, are in various stages of construction and planning, requiring significant financial resources. 

With this approval, MMRDA is now authorised to seek loans from multilateral agencies such as the Asian Infrastructure Investment Bank and the Asian Development Bank. However, MMRDA will be solely responsible for repaying the loans along with interest and other liabilities. The state's role is strictly as a guarantor. Officials noted that the combined cost of the six corridors exceeds Rs 36,000 crore. This financial backing is essential to prevent project delays, manage costs, and ensure that tendering and contracting processes proceed without obstacles.
