New Delhi, December 24, 2025: The Union Cabinet on Wednesday approved Phase-IV A of the Delhi Metro Rail Project, marking a significant expansion of the capital’s mass rapid transit network and giving a fresh push to sustainable urban mobility in the National Capital Region.
The approved phase will add nearly 16 kilometres to the Delhi Metro network over the next three years, with the construction of 13 new stations. Of these, 10 stations will be underground while three will be elevated. The project has been sanctioned at a cost of ₹12,015 crore.
Union Minister Ashwini Vaishnaw, announcing the decision, said the Delhi Metro has transformed everyday commuting in the capital and the new expansion would further strengthen connectivity and convenience for millions of passengers. He described Phase-IV A as another important milestone in the evolution of Delhi’s public transport infrastructure.
With this addition, the total length of the Delhi Metro network is expected to cross the 400-kilometre mark, substantially expanding its reach across Delhi and neighbouring regions.
The expansion will span three major corridors. The Ramakrishna Ashram Marg–Indraprastha corridor will be the longest, stretching 9.9 kilometres at an estimated cost of ₹9,570.4 crore. The Aerocity–Airport Terminal-1 corridor will cover 2.3 kilometres with an outlay of ₹1,419.6 crore, while the Tughlakabad–Kalindi Kunj corridor will extend 3.9 kilometres at a cost of ₹1,024.8 crore.
Officials said the project is expected to significantly improve last-mile connectivity, reduce traffic congestion on key arterial roads and promote environmentally sustainable modes of transport across the capital.
The Cabinet’s approval came on the same day that the Delhi Metro completed 23 years of operations. Since its launch, the network has grown to over 352 kilometres with 257 stations across ten lines, including the Airport Line, establishing itself as one of the largest and most efficient metro systems globally.
Adding to its achievements, the Delhi Metro Rail Corporation was recently selected for the ICI Awards 2025 by the Indian Concrete Institute, Chennai. The award, under the “Outstanding Prestressed Concrete Structure in the Country” category, was given for the Maujpur–Majlis Park corridor.
The Maujpur–Majlis Park stretch is a key component of the broader Phase-IV expansion and serves as an extension of the Pink Line. Once fully completed, it is set to become India’s first circular ring metro line, a development expected to significantly enhance cross-city connectivity and urban mobility in the national capital.
