Preparations have started for the proposed extension of Mumbai Metro 11 from Wadala to Bandra Terminus through Dharavi. Before construction begins, the Mumbai Metro Rail Corporation (MMRC) has started the process of checking and mapping underground utilities along the planned route. This extension is part of the larger Metro 11
project, which will connect Wadala to the Gateway of India through important areas such as Nagpada and Crawford Market.
Mumbai Metro 11 Tender Invitation
MMRC has invited tenders to appoint an agency that will carry out underground utility surveys in crowded areas along the proposed metro route. The survey will help identify underground structures and services before digging and construction begin.
According to an MMRC official, the work will include using Ground Penetrating Radar (GPR) technology to scan underground areas up to a depth of five metres. The survey team will map water pipelines, electricity cables, telecom lines, and other underground utilities. They will also prepare detailed reports, plans, and photographs of the findings.
The selected consultant will work with different government departments and agencies to collect information about underground obstacles. A final report is expected to be submitted within one month after the consultant is appointed. In March, the Maharashtra government directed MMRC to extend the metro line by 6.9 kilometres from Wadala to Bandra Terminus via Dharavi, and the project area is spread across nearly eight hectares.
Mumbai Metro 4
Earlier, this route was planned as an extension of Metro 4, which connects Wadala, Ghatkopar, Thane, and Kasarvadavali. Now, the line will also branch towards Bandra Terminus to improve railway and metro connectivity. During the 2026-27 Maharashtra budget, the government estimated the cost of the original 16.5-kilometre Metro 11 project at ₹23,487 crore.
In September 2025, the state cabinet approved the project. The Brihanmumbai Municipal Corporation will contribute ₹2,411 crore, while the Mumbai Port Authority will provide ₹804 crore. The state and central governments will each contribute ₹3,137 crore, and the remaining ₹12,163 crore will be arranged through institutional loans.
