The Kolkata Metro will be the first project in India to have an underwater tunnel. The construction of the tunnel, which will run under the river Ganga, has already started. It is part of the Kolkata Metro's east-west corridor. Visiting the site, Union Minister Babul Supriyo said, "this is the first such project in the country. Building a tunnel under the river had never taken place elsewhere in India. Further, being built under the Ganga, it has an emotional value as well."
