India’s first eight-lane tunnel on the Delhi-Mumbai Expressway, passing through the Mukundra Hills Tiger Reserve (MHTR) in Rajasthan, is nearing completion. The tunnel features two parallel tubes, each designed with four lanes. Spanning a total of 4.9 km, it includes a 3.3 km underground section, while the remaining 1.6 km is being built using the cut-and-cover technique.

The construction of Tube-1, which connects Kota to Chechat, has been successfully completed. Engineers and workers marked this milestone following the full excavation of the section. Meanwhile, Tube-2, running from Chechat to Kota, is also nearing completion, with only 60 meters of excavation remaining. This final phase is expected to be finished within a month.

Following the completion of excavation, additional modifications will be carried out to expand the tunnel’s width and height in specific sections. The entire excavation process is projected to be completed by June 2024. After this, road construction and other necessary infrastructure work within the tunnel will commence, ensuring it is fully operational for traffic in the near future.
