Union Education Minister Dharmendra Pradhan on Wednesday, 1 July 2026 announced that the Union Cabinet, under Prime Minister Narendra Modi, has approved a ₹6,969 crore project to construct an 8.1-kilometre tunnel connecting Dwarka Expressway with Vasant Kunj in the national capital, promising faster access to Indira Gandhi International (IGI) Airport and a significant easing of Delhi's chronic traffic congestion.

Context

Pradhan shared the Cabinet decision on X, describing it as 'another milestone in building a modern, connected and future-ready National Capital.' The approved tunnel will physically link the western arterial corridor of Dwarka Expressway — a major road project designed to ease west Delhi commutes — with Vasant Kunj, a densely populated residential and commercial zone in south Delhi. The alignment places the tunnel on one of the city's most congested travel axes, directly serving millions of daily commuters and air travellers.

Policy Backdrop

The decision fits within a decade-long federal push to upgrade multi-modal connectivity across the Delhi-NCR region. The National Infrastructure Pipeline, unveiled in 2019, had identified urban road and tunnel investments in the capital as priority projects, recognising the growing strain on surface roads linking the airport belt with southern and western residential corridors. Successive Union Cabinets have approved elevated corridors, expressways and underground routes as part of the broader National Capital Region transport integration plan that weaves together road, metro and expressway networks. The IGI Airport, India's busiest aviation hub handling over 7 crore passengers annually, sits at the centre of this connectivity grid, making last-mile road access a persistent policy concern.

The tunnel project is among the larger single-package urban road investments cleared in recent years, with the ₹6,969 crore outlay reflecting both the engineering complexity of sub-surface construction beneath a built-up metropolitan area and the scale of traffic relief expected. Central funding routed through the Cabinet underscores the government's intent to treat Delhi's congestion as a national infrastructure problem rather than a purely municipal one.

Stakeholders and Impact

Delhi commuters travelling between the western suburbs and south Delhi stand to benefit most directly, as the tunnel is expected to cut travel time on one of the city's most gridlocked corridors. Residents of Vasant Kunj, Dwarka and adjoining sectors — as well as the large volume of passengers heading to and from IGI Airport — are the primary beneficiaries. Beyond individual travel time, reduced surface traffic is expected to lower vehicle emissions along the affected stretch, contributing to air-quality goals that have become an increasingly prominent part of urban planning in the capital.

Real-estate stakeholders in both Dwarka and Vasant Kunj are also likely to watch the project closely, as improved sub-surface connectivity historically influences property values and commercial activity along newly linked corridors.

What's Next

The Cabinet approval marks the sanction stage; execution will require a detailed project report to be cleared by the implementing agency — likely NHAI or the Delhi PWD — followed by land and right-of-way notifications for underground utilities. Observers will track whether linked metro or elevated corridor announcements emerge in the 2026-27 budget cycle to complement the tunnel's capacity. The project's timeline, tendering process and construction commencement date are yet to be officially notified, and those milestones will determine when Delhi commuters see tangible relief on the ground.
