Delhi Metro Rail Corporation (DMRC) has initiated the bidding process for the construction of a major segment of the Phase 4 Green Line extension, linking Inderlok to Indraprastha. The move is expected to significantly ease urban mobility across central, east and northwest Delhi, while reinforcing the city’s shift toward sustainable public transport systems.
The corridor, approved by the Union Cabinet in March 2024, will cover 12.3 kilometres, of which 11.3 kilometres will run underground. The newly announced tender calls for the design and execution of twin tunnels using shield tunnel boring machines (TBMs), cut-and-cover tunnel sections, underground ramps and four new underground metro stations—at Dayabasti, Sarai Rohilla, Ajmal Khan Park, and Jhandewalan Mandir.The tender, released on May 20, mandates a project completion timeline of 42 months from the date of awarding. Interested contractors must submit their bids by July 8, along with a bid security of ₹240 crore. The high-value contract also includes additional work on the entry and exit points of a fifth underground station at Nabi Karim, along with launch and retrieval shafts, drainage systems, architectural finishes and provision of water supply—highlighting the DMRC’s emphasis on both functional and aesthetic commuter environments.
This metro extension is a crucial part of Delhi Metro’s broader Phase 4 expansion plan, which aims to add 103 kilometres of new lines across the National Capital Region. The Inderlok–Indraprastha section will house 10 stations: Inderlok, Dayabasti, Ajmal Khan Park, Jhandewalan Mandir, Nabi Karim, New Delhi, Delhi Gate, Delhi Sachivalaya, and Indraprastha. Five of these will serve as interchange stations, offering seamless integration with the Red, Yellow, Magenta, Violet and Blue lines.Planners believe that this new corridor will serve as a vital east-west conduit, reducing travel time and road congestion while improving last-mile connectivity in central Delhi. Commuters from Bahadurgarh and adjoining areas in Haryana will be able to travel on the Green Line directly to Indraprastha, facilitating quicker access to key government offices, commercial zones, and multimodal transit hubs.
This tender release comes shortly after DMRC received its first disbursement of ₹4,309.53 crore from the Japan International Cooperation Agency (JICA), part of a larger ₹6,252.91 crore financing agreement. The total investment for the three pending Phase 4 corridors, including the Inderlok–Indraprastha line, is estimated at ₹14,600 crore. The JICA funds have fast-tracked the tendering and construction activity for this corridor, along with the Saket G Block to Lajpat Nagar stretch and the Rithala–Narela–Nathupur corridor.Other Phase 4 corridors—Janakpuri West to RK Ashram Marg, Majlis Park to Maujpur, and the new Golden Line from Aerocity to Tughlakabad—are already under construction and expected to be operational by 2026. The Pink Line extension is likely to be completed by the end of this year.
DMRC’s continued investment in underground metro infrastructure reflects its commitment to sustainable, zero-carbon, and inclusive city-building. As Delhi prepares for increasing urban density and more frequent climate disruptions, high-capacity underground transit systems such as the Green Line extension are emerging as essential tools for a liveable, equitable urban future.
