New Delhi: The Union Cabinet on Wednesday approved three new corridors under Delhi Metro’s Phase V (A) project, covering a total length of 16.076 km, aimed at improving connectivity across central, south and airport-linked areas of the national capital.
The approved corridors are R.K. Ashram Marg–Indraprastha (9.913 km), Aerocity–Indira Gandhi Domestic Airport Terminal 1 (2.263 km) and Tughlakabad–Kalindi Kunj (3.9 km). The total project cost has been estimated at Rs 12,014.91 crore, to be funded by the Government of India, the Government of Delhi and international funding agencies.
According to the Government, the R.K. Ashram Marg–Indraprastha corridor will provide direct metro connectivity to the Central Vista area, including Kartavya Bhawans, benefiting around 60,000 office-goers and nearly two lakh visitors daily. The corridor is an extension of the Botanical Garden–R.K. Ashram Marg line and is expected to improve access between west, north and old Delhi and Central Delhi.
The Aerocity–IGD Airport Terminal 1 and Tughlakabad–Kalindi Kunj corridors are extensions of the Aerocity–Tughlakabad corridor and will strengthen airport connectivity with south Delhi areas such as Saket, Chhatarpur and Kalindi Kunj. Together, the three corridors will comprise 13 stations, of which 10 will be underground and three elevated.
The Government said the metro extensions are expected to reduce road congestion, lower fossil fuel consumption and contribute to reduced vehicular pollution. The Magenta Line and Golden Line extensions under Phase V (A) are also expected to support economic activity by improving access to central Delhi and the domestic airport.
Stations planned on the R.K. Ashram Marg–Indraprastha section include R.K. Ashram Marg, Shivaji Stadium, Central Secretariat, Kartavya Bhawan, India Gate, War Memorial–High Court, Baroda House, Bharat Mandapam and Indraprastha. The Tughlakabad–Kalindi Kunj section will include Sarita Vihar Depot, Madanpur Khadar and Kalindi Kunj, while Aerocity will be further connected to IGD Terminal 1.
Meanwhile, construction work on Delhi Metro Phase IV, comprising 111 km and 83 stations, is underway. The Government said around 80.43 percent of civil construction work on the three priority corridors has been completed, with phased completion expected by December 2026.
Delhi Metro currently operates a network of about 395 km with 289 stations across Delhi and the National Capital Region. It caters to an average of 65 lakh passenger journeys daily, with the highest-ever ridership of 81.87 lakh recorded on August 8, 2025.
