KMRC digging deepest station with twin tunnels

Kolkata Metro Rail Corporation (KMRC), currently engaged in creating an engineering marvel in the construction of East-West Metro station at Esplanade where one would have to climb down eight-storey to reach the metro station. The station will be 28 m deep so that the twin tunnels, which will take S N Banerjee Road and travel towards Sealdah, can steer clear of the North-South tracks. The inter-change East-West station — to be linked with the existing North-South corridor through a subway — will have four tiers. Construction major ITD Cementation, under supervision of KMRC is building the structure, which is one of India's deepest Metro stations. The East-West station coming up inside Howrah station's new complex is 30 m below the surface. Considering the depth, five escalators will be installed at the Esplanade multi-tier station, which aligns with the North-South corridor on the mezzanine level. Ticket counters will come up on this level since it's the first space commuters will access. Then comes upper concourse — the space has been reserved for a commercial complex — followed by the lower concourse'. This floor will have the base slab and double discharge platforms leading to twin tunnels. Since each floor of the East-West station covers 7,525 sqm area, the total built-up space of the four-tier station is 30,000 sqm. ITD Cementation has adopted the conventional cut-and-cover method of construction for executing the mega metro project.
