The diaphragm wall DW-40 for the subway connecting Jai Hind (Bimanbandar) station to the Netaji Subhash Chandra Bose International Airport (NSCBI) Terminal Building was recently finished, marking an important milestone in the Bimanbandar Metro Project.
The construction of the diaphragm wall cage, which is 17.405 metres long, 4 metres wide, and weighs 15 MT, began on May 2, 2023, at 3 p.m., and was completed the next morning. The road near the Airport Volvo Bus stand was closed from 10:30 p.m. on May 2 to 7:56 a.m. on May 3 due to the necessary traffic diversion.
To ensure safety during the road closure, precautions such as traffic signage and the deployment of traffic marshals were put in place. The Metro Railway CPRO, Kausik Mitra, thanked the Airport Authority of India and the Bidhannagar Commissionerate for their assistance in overcoming obstacles in the execution of the Bimanbandar Metro Project.
Once completed, the subway will provide an important link between the airport terminal and Jai Hind station, making it easier for visitors to access public transportation in Kolkata.
