The Chief Minister's Office of Karnataka announced on 2 July 2026 that a foundation stone has been laid for a new three-lane tunnel in Bengaluru, connecting the Hebbal Flyover to the staff quarters of the University of Agricultural Sciences (UAS), under the leadership of Deputy Chief Minister D.K. Shivakumar, who holds charge of Bengaluru's development.

The official post, written in Kannada, states: 'ಮುಖ್ಯಮಂತ್ರಿ ಶ್ರೀ @DKShivakumar ಅವರ ಮುಂದಾಳತ್ವದಲ್ಲಿ ಬೆಂಗಳೂರು ನಗರದ ಚಿತ್ರಣ ಬದಲಾಗುತ್ತಿದೆ' ('The face of Bengaluru city is changing under the leadership of Deputy Chief Minister Shivakumar'). It notes that the tunnel foundation stone was laid within days of the inauguration of the S.M. Krishna Dashapatha Road — a 10-lane road named after former Chief Minister S.M. Krishna — signalling the state government's intent to deliver signal-free, congestion-free corridors in rapid succession.

Context

Bengaluru's road network has long struggled to keep pace with vehicle growth that has historically exceeded 10 percent annually. The Hebbal junction in northern Bengaluru is among the most congested nodes in the city, serving as the gateway to the airport expressway and several residential and institutional zones. The proposed three-lane tunnel is designed to take vehicles beneath the existing surface grid, offering a signal-free passage between the flyover and the UAS GKVK campus area.

The CMO's post frames the project as part of a broader transformation of the city's mobility landscape, promising relief to commuters who have long faced gridlock at traffic signals on this corridor.

Policy Backdrop

Grade-separated road infrastructure has been a recurring priority across successive Karnataka governments. A signal-free corridor programme between 2017 and 2022 saw the construction of multiple elevated roads and underpasses across Bengaluru. A tunnel corridor proposal for central Bengaluru was floated in 2019, later shelved, and subsequently revived in a modified form.

The current Congress government, which came to power in 2023, has positioned urban infrastructure delivery — particularly in Bengaluru — as a key governance benchmark. The near-simultaneous inauguration of the S.M. Krishna Dashapatha Road and the tunnel foundation stone event reflects a deliberate sequencing of announcements to signal momentum.

Stakeholders and Impact

The primary beneficiaries are northern Bengaluru commuters, including residents of areas around the Hebbal, Yelahanka, and GKVK zones, as well as students, faculty, and staff of the University of Agricultural Sciences. The tunnel, once operational, is expected to reduce travel time on one of the city's most delay-prone stretches.

Historically, however, tunnel and elevated corridor projects in Bengaluru have faced challenges including land acquisition delays and cost escalations. Civil society groups and urban planners have also raised questions about whether grade-separated road projects adequately address long-term mobility needs compared to mass transit expansion.

What's Next

The immediate milestone to watch is whether the Hebbal-UAS tunnel moves from foundation stone to active construction within the current financial year. Budget allocations for the project in the 2026-27 Karnataka state budget and any environmental or land clearance updates will be key indicators of implementation pace. The state government's ability to deliver this project on schedule will be closely watched given the city's track record with large infrastructure timelines.
