Rescuers recently reached the 41 workers trapped in India’s under-construction road tunnel, overcoming the last obstacle.

One of the rescuers told the BBC that “the moment we knocked down the last section of debris, there was ‘an outburst of happiness in the tunnel.’

“The trapped people started clapping and shouting excitedly. The rescuers then asked them to stay calm, to be patient. They were told, “we will take you out one by one”.

Steel pipe that will allow them to be retracted through it on the surface the trapped workers have been introduced up to 52 meters inside the tunnel.

Since November 12 when the under construction underground road tunnel collapsed, rescue operations were complicated and delayed by falling debris and successive breakdowns of drill rigs vital to rescuing the workers.

The 41 workers have been kept alive for two weeks xmars in their supply of air, food, water and electricity current through a conduit through which the rescuers passed and an endoscopic camera. It allowed their families to see them last week for the first time since the under-construction road tunnel collapsed.

A makeshift health care facility has been set up, inside the tunnel, for first aid once the trapped workers begin to emerge. A team of doctors and nurses has been deployed with essential medicines.
