Karnataka High Court Keeps Hebbal Tunnel Construction Moving
A court in Karnataka was asked to stop a tunnel project near Hebbal lake in Bengaluru.
The people who filed the case worry that construction could harm the lake and its water channels.
The government says the tunnel will not block water or use land from the lake bed.
The court did not stop the work for now.
However, it wants an engineer to explain how water will continue flowing safely.
The tunnel is meant to reduce traffic.
It will run near the Hebbal Flyover Junction and through the GKVK campus.
The project is planned to be 2.5 kilometres long and toll-free.
The court will consider the issue again after receiving more information.
The Karnataka High Court refused to temporarily halt the proposed tunnel near Bengaluru’s Hebbal lake.
The government said the project would not take lake-bed land or obstruct water inflow and outflow.
Petitioners argued construction could violate lake-protection rules and affect stormwater drains beneath the tank bed.
The court ordered an engineer to explain how water flow would be protected before next week’s hearing.
The 2.5-kilometre, toll-free tunnel is projected to cost Rs 1,385 crore and take 18 months.

Petitioners’ concerns
Government’s position
Effect on Hebbal lake
Petitioners’ concerns
The petitioners say the tunnel would pass beneath the tank bed, where stormwater drains are located, and could affect the lake’s inflow.
Government’s position
The government says water inflow and outflow will not be obstructed and that the lake can continue to be used for any purpose.
Legality of construction
Petitioners’ concerns
The petitioners argue that Section 12 of the Karnataka Tank Conservation and Development Authority Act bars construction within 30 metres of the lake and ask the court to strike down the 2025 amendment.
Government’s position
The government relies on the amended provision, which permits construction if tank capacity is not reduced and natural water inflow or outflow is not obstructed.
Need for interim halt
Petitioners’ concerns
The petitioners requested protection preventing use of land near the lake until the legal and environmental concerns are resolved.
Government’s position
The court declined to halt construction immediately, saying it needed evidence that water inflow or outflow was actually being obstructed.
