Operating 24×7 on a war footing, the project aims for completion by December 2028.

The 200mt long, 50mt wide, and 35mt deep launching shaft will serve as the entry point for lowering and assembling the tunnel boring machines (TBMs). Two advanced TBMs are required for the twin tunnels. All components of the first TBM have arrived, but tunnelling will commence in August 2026.

Components of the second TBM are expected by December 2025, with assembly completed by October 2026, after which mining operations will begin.
