• It is a 4.531 km long, two-lane bi-directional tunnel with an escape passage, located on the Dharasu-Yamunotri section in Uttarakhand. 
• Barkot and Silkyara are the two ends of the tunnel. 
• Part of NH-134 (formerly NH-94), the project is being constructed under the Engineering, Procurement, and Construction (EPC) Mode.
• Around ninety percent of the tunnel is being excavated in phyllite, which is very weak rock.
• The New Austrian Tunnelling Method (NATM) is used for the construction of the tunnel. 
• NATM is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunnelling. 
• Funded under the National Highway Original [NH(O)] Scheme of the Ministry of Road Transport & Highways, it is a key component of the ambitious Chardham Plan.
• It promises to cut travel time by about an hour and improve accessibility, particularly during adverse weather conditions.
