As construction for Phase 3 of the Namma Metro project accelerates, concerns are rising over the environmental impact it may have on the city. The Bangalore Metro Rail Corporation Limited (BMRCL) has proposed building two new elevated corridors stretching a total of 44.6 kilometers—JP Nagar Phase 4 to Kempapura (32.1 km) and Hosahalli to Kadabagere (12.5 km). However, this expansion could result in the cutting of over 11,000 trees.
In anticipation of public concern, BMRCL has launched a three-day public consultation process beginning July 21 to seek input from citizens, environmentalists, and urban stakeholders. Officials said only essential trees will be cut and the rest will be relocated wherever possible. The affected routes will pass through key green stretches including JP Nagar, Hebbal, and Magadi Road.
On average, about 250 trees per kilometer may be impacted by the construction. This has triggered mixed responses—while some citizens and legal groups have demanded a review of the Detailed Project Report (DPR), others have voiced support for long-term urban transport solutions, provided that ecological damage is minimized.
Officials acknowledge that failing to act transparently could delay the project, as seen during the Blue Line’s legal disputes over tree removal. BMRCL has assured that all feedback received during consultations will be evaluated before moving forward. Environmental experts have been formally invited to provide guidance on mitigating the ecological impact. The corporation aims to strike a balance between infrastructure development and Bengaluru’s pressing need to preserve its green cover.
