Kolkata all set for first underwater metro services,
India’s first underwater river tunnel is almost ready. As part of the east-west corridor, Kolkata Metro Rail Corporation (KMRCL) has dug tunnels below the Hooghly River to lay train tracks. Of the 16.6-km-long east-west stretch, 520 m will be under the river bed. Constructing the tunnels has been an engineering feat. The tunnels are built more than 33 meters below the riverbed and will connect Kolkata to Howrah.
The fact that not one drop of water can enter the tunnel was the biggest challenge. The time taken to cross the 520-m tunnel will be around 60 seconds. Using the ferry to cross the river takes 20-odd minutes. And crossing the Howrah Bridge may take hours if you are stuck in a traffic jam.
The metro tunnel has several other marvels. The structure is actually made of rings that are 1.4 m wide. A special gasket has been made which will swell five times if it comes in contact with water. In case water ever enters the tunnel there are enough precautionary steps that have been taken.
