The assigned contractor will be required to deploy two new tunnel boring machines (TBMs) with one TBM on stand-by.

Twin tunnels will pass through the Military’s Maidan area, near Fort William, and an agreement on its alignment with Ministry of Defence (MoD) has taken a good 10 years to materialize.

If things go according to the prescribed schedule, then we should see a contractor getting assigned in the 2nd half of 2023, with tunneling work starting in the 2nd half of 2024.
