Govt Explores Lalbagh Tunnel Alternatives After Public Protests
The Karnataka government wants to build a tunnel road across Bengaluru.
The road would connect Hebbal with the Central Silk Board area.
People worried that the project could use land from Lalbagh, a famous botanical garden.
Citizens and environmentalists held protests, including a human chain.
The government then withdrew a bill that could have allowed some park land to be used for infrastructure.
Officials are now searching for routes that do not touch Lalbagh.
They are studying places such as NIMHANS land, cemetery land near Wilson Garden and Lalbagh Road.
Experts also warned that digging could harm very old rocks and nearby groundwater.
The Karnataka government is examining alternative routes for a proposed 17.5-km tunnel road to avoid Lalbagh.
Officials are considering alternative entry and exit points, including NIMHANS land, cemetery land near Wilson Garden, and a route beneath Lalbagh Road.
The move follows protests by citizens, environmentalists, walkers and opposition parties against using park land for infrastructure.
The Karnataka Government Parks Preservation Amendment Bill, 2026, was withdrawn after public opposition to allowing infrastructure use of up to five per cent of park land.
The Geological Survey of India warned that construction could threaten Lalbagh’s ancient Peninsular Gneiss formation and affect nearby groundwater flows.
