The National Highway Authority of India (NHAI) announced on Thursday that another milestone has achieved on the Delhi-Mumbai highway with the advance of a second tube of the eight-lane tunitive, which passes through the ecology in the Rajasthan ecology kota, without altering the fauna endangered in the region.
The first four -kilometer tunnel and eight kilometers from India is being built using the new Austrian tunnel method with multiple referrals. It is also worth mentioning that the sensitive ecological area of the Tigre Mukundra reserve has a low tree density.
In a series of publications on the social media platform X, the NHAI said that the successful adoption of the new Austrian tunnel method in hard terrain reflects the technical excellence of “NHAI, the ecological approach and the dedication to the infrastructure that it respects and preservation.
“The twin tunnel covers 4.9 km, including a 1.56 km cover of both ends, and an underground tunnel of 3.33 km. The construction raised unique challenges due to its low lid terrain and was built using the advanced tunnel method of New Austria, ensuring a minimum environmental impact,” reads one of the publications.
The ambitious tunnel of 4.9 kilometers is the first of his son in India, with eight lanes divided into two parallel tubes, each with four lanes.
Last month, the innovative ceremony for the first tube between Kota and Chehat was Hero. The second advance is for the tunnel between Chechat and Kota. Currently, the distance is approximately 70 kilometers, and the tunnel will reduce it significantly.
The construction of the tunnel was delayed due to a design change after the NHAI could not obtain environmental authorization, an official said. News18.
Of the 1,386 kilometers of the Delhi-Mumbai highway, a total or 373 kilometers fall into Rajasthan. The full section in Rajasthan, except for three packages with a collective length or 46 kilometers, is operational, said the official.

The highway includes two “eight -lane iconic tunnels,” according to the Ministry, which calls the thesis a will to the country’s engineering projection.
Another four km tunnel of eight lanes will pass through the ecological area of Matheran in Maharashtra.
