Karnataka Laws Ignite Controversy Over Bengaluru Tunnel Road
Karnataka passed two new laws about parks and traffic projects in Bengaluru.
One law allows up to 5% of protected park land to be used for public projects.
Critics worry this could make it easier to build a tunnel through or near important parks.
The other law gives some older transport projects automatic approval under a newer transport authority.
Critics say this may avoid normal checks by transport experts.
The proposed tunnel would run 16.75 kilometres between Hebbal and Silk Board.
The government says it will reduce traffic and will not damage Lalbagh Garden.
The opposition and some experts prefer improving Bengaluru’s Metro system instead.
The Adani Group submitted the lowest bid, but its price was higher than the government’s original estimate.
Karnataka’s legislature passed two Bills allowing limited park-land use and retrospective clearance for urban mobility projects.
Opposition leaders and environmentalists say the park amendment could enable commercialisation and tunnel construction through protected green spaces.
Chief Minister D K Shivakumar says the tunnel will pass beneath Lalbagh without affecting the garden, apart from possible temporary construction use.
The BMLTA amendment would deem projects begun since 2023 cleared under the authority’s law, despite concerns about bypassing expert scrutiny.
The 16.75-km Hebbal–Silk Board tunnel is estimated by the government at Rs 17,698 crore, while Adani Group bid Rs 22,267 crore.
- Who
- The Karnataka government, Chief Minister D K Shivakumar, the opposition BJP, environmentalists, urban mobility experts, and the Adani Group are central to the controversy.
- What
- The state passed amendments concerning park-land use and retrospective transport-project clearances, amid debate over a proposed Bengaluru tunnel road.
- Where
- Bengaluru, Karnataka, including the proposed route between Hebbal and Silk Board and areas near Lalbagh Botanical Garden and Hebbal Lake.
- When
- The Bills passed both Houses on August 24, 2026, during a short monsoon session; Gautam Adani met Shivakumar the previous day.
- Why
- The government says the changes are needed for public utilities, administrative continuity, traffic decongestion, and Bengaluru’s mobility challenges; critics say they could bypass scrutiny and facilitate the tunnel project.

Use of park land
Government and Project Supporters
The government says the amendment is limited to public utility projects and allows only up to 5% of park land to be used. Shivakumar says Lalbagh itself will not be affected, although a small area might be used temporarily for construction storage.
Opposition and Project Critics
The BJP and environmentalists argue that the amendment weakens protections and could open parks to commercialisation and state infrastructure projects. Tejasvi Surya has specifically raised concerns about land near Lalbagh and Hebbal Lake.
Tunnel road’s transport value
Government and Project Supporters
Shivakumar says the tunnel road would help ease Bengaluru’s traffic burden and address the city’s mounting mobility problems.
Opposition and Project Critics
The BMLTA’s feasibility review said the project does not align with Bengaluru’s Metro-centric Comprehensive Mobility Plan, Climate Action Plan, or the National Urban Transport Policy. Critics say tunnel roads encourage car-based commuting and favour Metro expansion instead.
Retrospective clearances
Government and Project Supporters
The government says deemed clearances are needed to ensure continuity in administrative decision-making and respond quickly to urgent mobility needs.
Opposition and Project Critics
Citizens, opposition leaders, and mobility experts say the amendment could circumvent BMLTA evaluation and provide retrospective approval to projects that did not undergo the required scrutiny and analysis.
Adani Group meeting and bid
Government and Project Supporters
The Chief Minister’s office described Gautam Adani’s meeting with Shivakumar as a courtesy visit, while Priyank Kharge said the Adani Group is already a government contractor in Karnataka and that nothing inappropriate occurred.
Opposition and Project Critics
The timing of the meeting—one day before the Bills passed—has added to the controversy, particularly because the Adani Group was the lowest bidder for the tunnel project at a price above the government estimate.

Karnataka Chief Minister
“The Adani Group has several projects in Karnataka. The ACC cement factory in Chittapur (Kharge’s constituency) was taken over by the Adani Group, the Mangalore Airport is operated by the group. So, the company is already operating projects in the state.”

“Bengaluru is already choking, stripped of its canopy, and desperate for green spaces. Instead of expanding and fiercely guarding our parks, this government views public open space as nothing more than a private land bank waiting to be monetised.”
