Kolkata is set to boost its urban mobility with the planned launch of the Noapara–Airport Metro line by July 2025. This key infrastructure project will offer direct metro access to Netaji Subhas Chandra Bose International Airport, cutting travel time and reducing traffic congestion on key routes.The initial phase spans 7 kilometres, linking Noapara to the newly built Jai Hind Metro Station at the airport. Intermediate stations such as Dum Dum Cantonment and Jessore Road will serve as vital nodes for daily commuters. The corridor forms part of the Yellow Line (Line 4), which will eventually extend to Barasat, integrating northern suburbs into the metro network.Jai Hind Metro Station, approximately 13 metres underground, is designed to be one of Asia’s largest underground metro facilities. Covering over 14,645 square metres, the station features five platforms, with infrastructure to support emergency services and future line extensions. Escalators, lifts, and travelator-equipped subways are included for improved accessibility and commuter comfort.Construction progress has been challenged by height restrictions around the airport and the relocation of underground utilities. Nonetheless, the project is advancing, with trial runs completed and safety inspections by the Commissioner of Railway Safety scheduled before launch.Beyond reducing airport travel time, the Noapara–Airport line is expected to promote sustainable mobility by encouraging the use of public transport over private vehicles, thereby cutting carbon emissions. It aligns with broader urban goals of equitable, inclusive, and environmentally conscious development.As Kolkata continues to expand its metro network, the upcoming launch of this link marks a significant milestone in its journey toward a modern, connected, and sustainable urban transport system.
