BRO completes excavation of Nechiphu tunnel in Arunachal.

Itanagar: The Border Roads Organization (BRO) on Friday completed the excavation of the Nichifu tunnel in Arunachal Pradesh’s West Kaming district.
Tezpur-based defense spokesman Lt. Col. AS Walia said the last blast was carried out by BRO Director General Lt. Gen. Rajiv Chaudhry.
Between 82 and 88 km along the Bali Para-Chaudhury -Twang Road, the 500 m Nichifu Tunnel, which connects Bali Para in Assam with Twang in Arunachal Pradesh, bordering China, is located at an altitude of 5,700 feet.
It is one of several tunnels that the BRO has envisioned to improve the geometrics of existing roads along border areas, to avoid foggy areas, to prevent slide-prone areas and to reduce dark spots on roads. In order to provide more security and all weather connectivity to the movement of military and civilian traffic. Lieutenant Colonel Walia.
Once in service, the Nechiphu Tunnel will not only provide all seasonal passages but also reduce travel time by 30 minutes and reduce road distance by up to 7 km due to heavy fog. He said that this eco-friendly construction and reduction in distance would also help in reducing the carbon footprint of roads in the area.
The tunnel has been constructed by cutting through the fragile mountains of the Himalayas through rigorous 3D monitoring and the active use of the required tunnel support system through a highly broken rock under low load.
A new tunnel method has been used in Austria to speed up construction. A defense spokesman said BRO personnel had set a record on the tunnel by digging 100 meters in just 40 days.
The tunnel will be provided with state-of-the-art electromechanical systems including firefighting devices, auto illumination systems and SCADA controlled monitoring systems.
It will also accommodate sidewalks on both sides for safe movement of pedestrians, including power lines, OFC cables and ducts for passing utility lines to strengthen civic infrastructure.
The Silla tunnel, which is also being excavated under the same project and was announced by the government in 2018, will be the longest twin-lane tunnel in the world as it will reduce travel time by at least an hour. As well as all-weather contact.
