Union transport minister, Nitin Gadkari, informed that the aggregate length of National Highway tunnels under operation is 31 km. Tunnels totalling 196 km in length are under implementation, besides, detailed project report for 135 km of tunnels is currently in progress. The construction of these tunnels is expected to be completed by 2026. Digitization of tunnelling along with other modern concepts need to be adopted for the construction of tunnels in India. With technological advancements, digitization will change the way geological data is gathered, rock classification is carried out as well as the application of design analysis required for carrying out tunnelling works.
