Delhi Metro’s network will expand by 16 km under Phase 5A, entailing a cost of ₹12,015 crore, as approved on Wednesday by the Union Cabinet.The central government, the Delhi government, and international funding agencies will fund the project, which will be completed in three years.
Under the fifth phase, the three corridors are R K Ashram Marg to Indraprastha (9.913 km), Aerocity to Indira Gandhi International Airport’s Terminal 1 (2.263 km), and Tughlakabad to Kalindi Kunj (3.9 km).
“After completion, the first corridor will improve the connectivity of West, North and Old Delhi with Central Delhi and the other two corridors will connect South Delhi with the domestic Airport Terminal-1 via Saket, Chattarpur etc., which will tremendously boost connectivity within the National Capital,” the Cabinet said in a statement.
The project will cover 13 stations, of which 10 will be underground and three elevated.
The RK Ashram Marg-Indraprastha section will be an extension of the Botanical Garden-R K Ashram Marg corridor.

“The Central Vista corridor will provide connectivity to all the Kartavya Bhawans thereby providing door step connectivity to the office goers and visitors in this area. With this connectivity around 60,000 office goers and 200,000 visitors will get benefited on a daily basis. These corridors will further reduce pollution and usage of fossil fuels enhancing ease of living,” the Cabinet added. The corridor will also provide direct subway connectivity between Rajiv Chowk and Shivaji Stadium on the airport line. The stations on the corridor will be R K Ashram Marg, Shivaji Stadium, Central Secretariat, Kartavya Bhawan, India Gate, War Memorial - High Court, Baroda House, Bharat Mandapam, and Indraprastha.
Among the second and third corridors, the stations on the Tughlakabad-Kalindi Kunj section will include Sarita Vihar Depot, Madanpur Khadar, and Kalindi Kunj, while the Aerocity station will be connected further with the airport’s T-1 station.
“These extensions of the Magenta Line and Golden Line will reduce congestion on the roads; thus, will help in reducing the pollution caused by motor vehicles,” the Cabinet said.
Delhi Metro is working on completing the much-delayed Phase 4 of its network.
“Construction of Phase-IV consisting of 111 km and 83 stations are underway, and as of today, about 80.43 per cent of civil construction of Phase-IV (3 Priority) corridors has been completed. The Phase-IV (3 Priority) corridors are likely to be completed in stages by December 2026,” the Cabinet said.
