SN Banerjee Road option for East-West Metro's ventilation shaft
TNN / Jan 13, 2023, 08:11 (IST)
Soil scientists have identified the open space on the Calcutta Technical School campus on SN Banerjee Road to build a new ventilation shaft for East-West Metro. The ground here is suitable for linking the shaft with the twin East-West Metro tunnels through micro-tunnelling. There is also a proposal for an evacuation shaft below Bowbazar's Durga Pituri Lane, where the grounds have already been firmed up with advanced chemical grouting. This way, the three contentious cross passages could be dropped.
