Delhi-Mumbai Expressway’s Longest Tunnel Nearing Completion

The longest tunnel on the Delhi-Mumbai Expressway, passing through Rajasthan’s Mukundra Hills Tiger Reserve, is close to completion. This eight-lane tunnel, the first of its kind in India, features two parallel tubes with four lanes each.

Spanning 4.9 km, the tunnel includes a 3.3 km underground section and a 1.6 km cut-and-cover stretch. Engineers and workers recently celebrated the breakthrough of Tube-1, which connects Kota to Chechat, marking a key milestone in the project.
