Kolkata Metro Line 3 is a line of the Kolkata Metro, that of 2019 is still under construction. The route spans from Joka in the south, to Esplanade in the north with an extension of 2 km to Diamond Park from Joka. It will connect Kolkata Metro Line 1 at Park Street in central Kolkata and run in parallel up to Esplanade in central Kolkata where it will connect Kolkata Metro Line 2 also. Line 3 is being built by Rail Vikas Nigam Limited.

Development

It is partially elevated and partially underground: around of the project will be elevated and the rest of the metro line will be underground. The project is getting delayed due to non availability of land for the construction of train depot at Joka. In 2019, RVNL was given the land required for building the depot and the construction for its boundary wall and land development started in February 2019. Tenders for its construction and plant & machinery were invited in April 2020.
Construction was further delayed in September 2018 due to the Majerhat Bridge collapse, the metro was being built right next to the bridge.
Tender for Majherhat to Esplanade underground section has been floated in 1st week of December 2019.
