Metro 7 of the Mumbai Metro is part of the metro system for the city of Mumbai, India. The 18.975 km line is partially elevated and partially underground., and consists of 23 (20 elevated and 3 underground) stations from Bhayander East to CSIA T2.
In February 2017, the MMRDA announced that the DMRC was preparing a detailed project report (DPR) on Metro 10, a proposed 9 km extension of Metro 7 from Dahisar to Bhayander, via Mira Road. Preliminary plans prepared jointly by MMRDA and DMRC, proposed a 9 km 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. 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$560 million). The DPR is expected to be completed by April 2017.
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 km 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 extension was approved by the State Cabinet on 12 April 2017. A 2.2 km underground tunnel from the Andheri signal will connect to the T2 terminal. The tunnel is expected to cost ₹600 crore, and construction is expected to begin in 2018.
In April 2017, the Civil Aviation Ministry provided 40 acres of land in Dahisar for the construction of the metro depot.
The bhoomipujan ceremony for Line 7 was performed by Prime Minister Narendra Modi during his visit to Mumbai in October 2015. Line 7 is being implemented through the engineering, procurement and construction (EPC) model. The project is estimated to cost ₹6,208 crore (US$960 million). Bids for the design and construction of the corridor were split into 3 packages, and awarded by the MMRDA in April 2016.
Construction work on the corridor began on 8 August 2016. The project is expected to be completed by mid-2019. The contractors are likely to complete construction of the corridor and all 14 stations within 30 months from the day of commencement of work. On 18 February 2017, MMRDA officials stated that 15% of piling, pile caps and pier work on the corridor had been completed. By the end of April, 25% of piling work, 60% of barricading work and 77% of the soil testing for pier foundation had been completed.
