The Cabinet Committee on Economic Affairs has approved the 6 Lane Dwarka Road Tunnel project on NH-148AE at an estimated cost of ₹6,969.67 crore. The 8.1-kilometer six-lane project will be implemented by the National Highways Authority of India under the Ministry of Road Transport and Highways using Hybrid Annuity Mode under the NH(O) Scheme.
The infrastructure project will connect the Shiv Murti Interchange on the Dwarka Expressway (NH-248BB) with Nelson Mandela Marg in Vasant Kunj, providing a high-speed, access-controlled link between West and South Delhi. The corridor's defining feature is a 3.14-kilometer twin-tube tunnel, including a 1.98-kilometer stretch beneath the Southern Ridge, designed to ensure seamless mobility while preserving Delhi's ecologically sensitive landscapes.
The project aims to reduce dependence on heavily congested routes including Dhaula Kuan–IGI Airport–Mahipalpur, Chhatarpur–Mahipalpur and Rangpuri, benefiting traffic from Gurugram, Dwarka, IGI Airport and West Delhi. It will strengthen integration between Delhi and Gurugram, improving access to key residential areas, commercial centres, institutional hubs and the Indira Gandhi International Airport.
The corridor will also improve access from the airport and Dwarka Expressway to several iconic destinations including Qutub Minar, Mehrauli Archaeological Park, Hauz Khas Heritage Complex, Humayun's Tomb, Lodhi Garden and Chhatarpur Temple. It will facilitate smoother travel to Bharat Mandapam, India Gate and other major venues hosting international conferences, exhibitions and cultural events.
The project is designed to support Delhi's hospitality, tourism and MICE (meetings, incentives, conferences and exhibitions) ecosystem by providing faster, more comfortable journeys for visitors. It will also improve connectivity between the airport and Delhi's diplomatic enclave, business districts, convention centres and institutional hubs, reinforcing Delhi's position as a leading centre for commerce, diplomacy and global engagement.
