In order to save the construction workers, who are trapped approximately 60 meters away in the Himalayan tunnel, the disaster management team has created an escape passage through which oxygen and food are supplied through a pipe.
The trapped workers are also being contacted through walkie-talkies.
The State Disaster Response Force (SDRF) and the National Disaster Response Force (NDRF), along with police and local administration personnel, are leaving no stone unturned to safely rescue the workers.
The rescue team removed debris inside the 13-meter-wide tunnel with the help of two JCBs and a Poclain machine.
Prashant Kumar, the Circle Officer of Uttarkashi, told Indian media that they have made progress of approximately 15 meters within the tunnel, with a remaining distance of about 35 meters to be covered.
"As of now, the situation is under control and not life-threatening,” Disaster Response Force (DRF) Inspector Jagdamba Bijalwan said.
NDRF's Assistant Commandant, Karamveer Singh Bhandari informed Indian media that they are facing some challenges in the rescue operation of the trapped workers due to the presence of wet debris.
Uttarakhand CM Pushkar Singh Dhami also reached the accident spot to take stock of the situation.
Offering support to the families of the trapped workers, Dhami affirmed that Prime Minister Narendra Modi has assured to provide all necessary assistance, and the state government and administration are diligently working towards their rescue.
An investigation has also been initiated to find out the cause of the tunnel collapse.
