How the tunnel is being built?

The tunnel boring machine, used in the excavation work, will now go beyond the slab number 840 to dig up earth under the river bed and finally reach the east bank - that is the city.

Cost of the project

The initial project cost for the Phase I - Phase II stretch had shot up due to realignment of the tunnelling, covering an additional 2 km and cost for elevation. The costs had gone up from Rs 250 crore in 2011-12 under the UPA rule to Rs 328.81 crore in 2015-16 and now Rs 1937 crore.
