The Kolkata Airport is undergoing expansion to increase its annual passenger handling capacity from 2.6 crore to 4.5 crore. A new terminal (T3) is being constructed, expected to be completed by November 2025, which will raise the total capacity to 3.3 crore passengers. This will enhance Kolkata's status as a travel hub, and stimulate economic growth.

The Kolkata Metro network is undergoing significant expansion, with plans to add 100 kilometers by 2026. Key projects include the Joka to Esplanade (Purple Line) and New Garia to Kolkata Airport (part of the Orange Line) sections. The Yellow Line extension from Noapara to Barasat and the Pink Line 5 are also under construction or planned.

The expansion of Kolkata Airport includes constructing a new terminal (T3) to increase its annual passenger capacity to 33 million, with an estimated cost of approximately ₹5000 crore, expected to be completed by November 2025. The government plans to enhance the airport's annual passenger capacity from 2.6 crore to 4.5 crore by constructing a new terminal, slated for completion by November 2025. Daily flight operations have already surged from 264 to 400. The airport will soon expand to operate flights to 100 destinations daily. The additional space will add roughly two million passengers to T2's annual capacity. By December 2025, this will lift T2's capacity to 28 million passengers. The new second passenger terminal (T2) at Kolkata Airport will feature 21 aerobridges. The expansion employs prefabricated structures to minimise disruption to T2's operations, which currently handle about 400 daily flights.

Kolkata Metro is undergoing significant expansion, aiming to add 100 kilometers to its network by 2026. This includes Phase 1 of the Joka to Esplanade (Purple Line) and New Garia to Kolkata Airport sections. The East-West Metro Corridor project aims to connect Salt Lake Sector V to Howrah Maidan. The New Garia-Airport Metro Link is set to connect New Garia to Netaji Subhas Chandra Bose International Airport. Three new metro rail services are set to be unveiled: the Noapara–Jai Hind Bimanbandar corridor to the international airport, the Sealdah–Esplanade line connecting the city center, and the Beleghata–Hemanta Mukhopadhyay route improving access to the IT hub. The airport metro link from Noapara to Netaji Subhas Chandra Bose International Airport is expected to begin service by July 2025, and plans are underway to extend the Purple Line metro to Eden Gardens, the Green Line metro to Teghoria, and the Yellow Line metro to New Barrackpore. By 2026, Kolkata Metro will induct a total of 131 new rakes. The upcoming launches include the 2.6 km Esplanade–Sealdah segment of the Green Line (East-West Metro's final stretch), the 7 km Noapara–Airport corridor on the Yellow Line (its first operational phase), and the 4.5 km Ruby–Metropolitan link on the Orange Line's Phase II.
