Rajasthan’s Critical 8-Lane Tunnel on Delhi-Mumbai Expressway to Open This Month
The 4.89-kilometre-long, eight-lane tunnel on the Delhi-Mumbai expressway in Rajasthan’s Kota district is set to open by the end of July, a senior official of the National Highway Authority of India (NHAI) said on Tuesday.
The tunnel, part of an 8.3 km section that cuts through the Mukundra Hills and a tiger habitat, is one of the most critical links of the 1,386-km expressway project. With a width of 22 metres and a height of 11 metres, it is among the widest tunnels in the country, passing through different rock masses and substrata including sandstone, shale, siltstone, mudstone and limestone.
In addition to the tunnel section, another 26-km section from Sawai Madhopur to Laban in Rajasthan will open for traffic by the end of July, the official added.
