According to officials, India’s first underwater tunnel for metro connectivity between Howrah and Kolkata is under construction and will be completely operational by 2023. 520 metres of the 16.6-kilometer east-west route will be beneath the Hooghly river’s riverbed.
The tunnel corridor would connect Kolkata and Howrah and will be built 33 metres below the riverbank. Kolkata Metro Rail Corporation (KMRCL) is building the Kolkata East-West Metro line, which will include an underground tunnel beneath the Hooghly river. Mithun Ghosh, the Site Supervisor, spoke on the project’s facilities and safety measures, saying that there will be walkways in the tunnels for passenger escape in the event of an emergency.
“Important Passage work has also been done,” Mithun explained, “bearing in mind that if a technical problem happens inside the water tunnel region, passengers can be transported out using the special passage.” He also stated that over 80% of the work on the East-West Howrah Metro station has been finished, with full service slated to begin in 2023.
“The station is being built at a depth of 33 metres beneath the Hooghly river. Eighty per cent of the work has been completed, with the remaining twenty per cent to be completed. By 2023, it will be operational “Ghosh continued.
