KOLKATA (Metro Rail News): This weekend, Afcons Infrastructure commenced construction on the diaphragm wall (D-wall) for Kolkata Metro Line-6 (Orange Line)’s underground airport tunnel as a component of Package ANVS-RVNL-1682. The northern terminal of Kolkata Metro’s 29.87 km Line-6 ( which connects Kavi Subhash New Garia to  Biman Bandar) will be the Airport Station, which will also serve as a stop on the 6.87 km Line-4 (Noapara – Airport). Line-4 will be extended northward to New Barrackpore.

ITD Cementation is currently constructing the station’s box with four lines and a train stabling facility. Afcons has been tasked with constructing an underground cut-and-cover tunnel spanning approximately 950m through the land of the Airports Authority of India.

In January 2021, Afcons was granted the Rs. 532.65 crore civil construction contract for Package ANVS-RVNL-1682, which must be completed within 36 months. This 3.519 km civil package, which is mainly elevated, will connect the Sub CBD-2 Station to Biman Bandar. Under this, two new stations at Chinar Park (formerly Rabindra Tirtha) and VIP Road (Haldiram), as well as underground sections and viaduct, are to be constructed.
