The Howrah station on the west side of the river will be at a depth of 30 meters. Tunnelling started from Howrah Maidan side, by Afcons. On 23 May 2017 one of the TBM named Rachna completed the tunneling under the Hoogly river in 36 days. The other TBM named Prerna also completed the tunnelling work under the river on 21 June 2017. There were some concerns during tunneling under Brabourne road as the tunnel would pass within 100 meters of heritage structures and there were also many old and dilapidated buildings in this section. KMRC received permission from Archaeological Survey of India in June 2017. Residents and shops in the old building were temporarily shifted and the buildings were reinforced before construction of tunnel.
