Citizens and walkers in Bengaluru formed two human chains and hugged the peninsular gneiss rock inside Lalbagh on Sunday to register opposition to the proposed Tunnel Road project. The demonstration was organised by the Lalbagh Walkers Association (LWA) and drew members of the public concerned about urban development plans. The action followed earlier efforts to raise awareness of what participants described as threats to the park. The event was peaceful and deliberately silent after organisers were denied permission for a formal protest inside the grounds. Organisers explained that the hug was chosen as a symbolic act to highlight potential irreversible impacts on the city's green cover, geological heritage and biodiversity. They warned that the ancient Lalbagh rock, a geological formation dating back millions of years, could be vulnerable to damage from blasting and excavation associated with tunnel construction. The protesters expressed alarm at the prospect of civil works in such a sensitive natural and historical site and urged authorities to reconsider the alignment and methods proposed. The association argued that heritage and ecosystems should be central to planning decisions. An environment activist raised concerns about the broader scope of the plan, noting that the proposed Tunnel Road project between Hebbal and Silk Board, the short tunnel between Hebbal and Veterinary College, the nine elevated corridors and the metro double-decker proposals would permanently damage the environment. He said that no detailed studies by independent experts had been made public and that the likely consequences could not be predicted without rigorous assessment. The activist appealed for transparent consultations and credible impact assessments before any construction proceeds. Members of civic groups echoed calls for expert review. Participants indicated they are planning a larger protest at Freedom Park to press for the entire Tunnel Road project to be scrapped in order to protect Bengaluru's botanical heritage and geological history. They framed Lalbagh as essential to the city's ecology and collective memory and urged decision makers to prioritise conservation over rapid infrastructure expansion. The groups said they will continue mobilisation until a response is received.
