Work for construction of the terminal station at New Garia for the 29.87 km (18.56 mi) Kavi Subhash-Biman Bandar (via Rajarhat) metro project finally resumed on 14 February 2017 with Rail Vikas Nigam Ltd (RVNL) demarcating the plot they require for the purpose.

The 5 km (3.1 mi) stretch from New Garia to Ruby Hospital was expected to start from 2018.

RVNL planned to launch the metro over this truncated route before this year's Durga Puja, but was postponed due to signalling issues.

[7] A week later after inauguration and a day after commercial run started on Kavi Subhash-Hemanta Mukhopadhyay section, RVNL announced the completion of a 76 m viaduct gap after construction of a single-span open-web girder steel bridge over Tagore Park culvert.

[8] Trial runs have started over Hemanta Mukhopadhyay-Beleghata metro station and this stretch is planned to open in late 2024.

On 4 January 2021 the state government decided to rename 9 metro stations in New Town area to their more prevailing names rather than using the old ones which were given during the planning phase.

The state transport department has informed Housing Infrastructure Development Corporation (HIDCO) of the new names of the proposed nine metro stations between Nazrul Tirtha at the entry of New Town from Salt Lake Sector V till Chinar Park, the last station on the line before it turns right on VIP road towards Kolkata Airport.
