# Line 9 (Mumbai Metro)

Red Line 9 (extension) of the Mumbai Metro is part of the metro system for the city of Mumbai, India. Metro Line 9 is an extension of the Red Line from Andheri to CSMIA and Dahisar to Mira Road. This line will be unique from the other metro lines because it will run on a double-decker bridge. There will be a flyover on the first deck and the metro will run on the second deck. The flyover will start near the proposed Shivaji Chowk (Mira Road) metro station and will end in Bhayander (West) via Mira Bhayander Road. It shall provide interconnectivity among the Western Express Highway, the Western Line, and the Mumbai Metro (Line 2 and Line 7).
J Kumar Infraprojects Ltd. has received a Letter of Acceptance (LoA) from Mumbai Metropolitan Region Development Authority (MMRDA) for the design and construction of Mumbai Metro Line 9. A maintenance depot has been proposed at Mira-Bhayandar (main depot for entire Red line). The depot is proposed behind Netaji Subhash Chandra Bose Stadium. This will be one of the biggest metro depots of Mumbai. Total land area proposed for maintenance facilities is 20.0 Ha.
It will be an 11.386 km (7.075 mi) line, carrying an expected 0.847 million commuters per day by 2021 and 1.112 million by 2031.

## Planning

In February 2017, the MMRDA announced that the DMRC was preparing a detailed project report (DPR) on Line 9, a proposed 9 km (5.6 mi) extension of Metro 7 from Dahisar to Bhayander, via Mira Road. Preliminary plans prepared jointly by MMRDA and DMRC, proposed a 9 km (5.6 mi) elevated extension of Metro 7 from Dahisar to Bhayander, via Mira Road. The extension will have 9 stations, with an inter-station distance of 1 km (0.62 mi). The line will run parallel to the Surat-Dahisar Highway, then turn left at Kashi Mira Junction, before passing through Mira Road-Bhayander, and terminating at Golden Nest Circle, Bhayander. The project is estimated to cost ₹3,600 crore (US$420 million). The extension was approved by the Maharashtra government in September 2018, and will be implemented as Metro 9. Prime Minister Narendra Modi laid the foundation stone for Metro 5 (Thane-Bhiwandi-Kalyan) and Metro 9 (Dahisar-Mira Bhayander) in December 2018, along with Maharashtra chief minister Devendra Fadnavis.
In March 2017, the MMRDA stated that the DMRC was conducting a feasibility study to extend the line to the T2 terminal of the airport. The proposed 3.17 km (1.97 mi) extension from Andheri to the domestic airport will pass beneath Line 1's WEH station and is expected to cost between Rs 1,500 and 2,000 crore. The extensions to Mira Road and the airport were officially announced by Chief Minister Fadnavis on 30 March 2017. The alignment for the extension from Andheri to Chhatrapati Shivaji Maharaj International Terminus was approved by the State Cabinet on 12 April 2017. The 3.17 km (1.97 mi) includes a 0.98 km (0.61 mi) elevated stretch and 2.11 km (1.31 mi) tunnel. The Maharashtra Cabinet approved the implementation of the extension, called Metro 7A, in September 2018. Work on Metro 7A is expected to begin by April 2019. Nine months after Prime Minister Narendra Modi laid its foundation stone in Bhiwandi, the construction work for the much-awaited Metro-9 (Dahisar to Bhayandar) route finally commenced in September 2019.
