To enhance traffic flow and decongest Delhi – Gurugram section of NH48, NHAI has begun trial run of the tunnel and underpasses on the Delhi section of Dwarka Expressway starting May 29, 2025.
The trial run on the tunnel, which is likely to be fully operational from June 5, 2025, marks a significant step toward enhancing mobility and reducing congestion in Delhi NCR, NHAI said in a statement.
Improving connectivity
NHAI noted that the tunnel’s strategic location and layout will benefit large number of daily commuters and reduce the burden on surface roads and reduce congestion by connecting Dwarka Expressway to the Indira Gandhi International (IGI) Airport.

Once operational, the underpasses shall provide alternate connectivity to IGI Airport through the shallow tunnel, improving connectivity between Delhi, Gurugram, and northern cities.
It will help to streamline traffic flow between key areas such as Gurugram, Vasant Kunj, Dwarka, Alipur as well as enhance connectivity with other corridors in & around Delhi-NCR to facilitate seamless movement of traffic from Gurugram, Faridabad, and Manesar towards northern destinations like Sonipat, Panipat, and Chandigarh.
Ensuring safety
NHAI further stated that the tunnel has been built using advanced engineering and safety features. It is equipped with CCTV surveillance, a dedicated control room, and emergency exits to ensure commuter safety and efficiency.Â

The tunnel will have a height restriction of vehicles upto 4.5 meters and slow-moving vehicles like two wheelers, three wheelers & vehicles carrying flammable materials like the oil tankers will not be allowed inside the tunnel and underpasses.
The underpasses opened for the trial run will include a shallow tunnel connecting Dwarka / Yashobhoomi to airport through airport underpasses & vice versa. Further, users can also ply towards Gurugram (towards Sirhaul) from Dwarka / Yashobhoomi through shallow tunnel and right turn underpass. Moreover, a combination of airport Underpasses along with Right turn underpass can be used from Terminal 3 to Gurugram (towards Sirhaul).
The trial period will help NHAI to monitor and evaluate traffic patterns, safety measures, and infrastructure efficiency to ensure seamless integration into the city’s transport network.
