Ganga tunnel of East West Metro is 1st of its kind: Minister
Union Minister Babul Supriyo on Monday said the underwater tunnel of East-West Metro Corridor Project in Kolkata, built below the Ganga river bed, is the first of its kind in the country. "Building a tunnel under the river had never taken place elsewhere in India. Further being built under Ganga, it has an emotional value as well," he added.
