At approximately 5:30 am on 12 November 2023, a section of the Silkyara tunnel under construction on the Yamunotri [[National Highway 134 (India)|National Highway]] in Uttarakhand collapsed. The collapse occurred around 200 meters from the entrance of the tunnel, trapping approximately 41 construction workers inside.<ref>{{Cite web |date=13 November 2023 |title=Uttarakhand Tunnel Collapse Live Updates: Workers to be rescued through large-diameter steel pipes inserted through rubble |url=https://indianexpress.com/article/india/uttarakhand-uttarkashi-tunnel-collapse-rescue-operation-workers-trapped-live-updates-9024269/ |access-date=14 November 2023 |website=The Indian Express |language=en |archive-date=14 November 2023 |archive-url=https://web.archive.org/web/20231114024716/https://indianexpress.com/article/india/uttarakhand-uttarkashi-tunnel-collapse-rescue-operation-workers-trapped-live-updates-9024269/ |url-status=live }}</ref> A team of geologists from the state government and educational institutions was sent to the scene in order  to determine the possible cause of the incident.<ref>{{Cite news |title=Heavy machinery brought in to pull out workers from collapsed tunnel in India |language=en |work=CNA |url=https://www.channelnewsasia.com/asia/india-collapsed-tunnel-uttarakhand-heavy-machinery-3918761 |access-date=15 November 2023 |archive-date=14 November 2023 |archive-url=https://web.archive.org/web/20231114141318/https://www.channelnewsasia.com/asia/india-collapsed-tunnel-uttarakhand-heavy-machinery-3918761 |url-status=live }}</ref>
== Rescue efforts ==
Two [[tunnel boring machine]]s have been deployed during the rescue efforts, the second (flown in
in three parts) after the progress of the first was insufficiently speedy.<ref>{{cite web |first1=Andrew |last1=Clarance |first2=Cherylann  |last2=Mollan |title=Uttarakhand tunnel collapse: New drill machine brings hope to trapped Indian workers |url=https://www.bbc.co.uk/news/world-asia-india-67435642 |website=BBC News |access-date=16 November 2023 |date=16 November 2023 |archive-date=16 November 2023 |archive-url=https://web.archive.org/web/20231116070448/https://www.bbc.co.uk/news/world-asia-india-67435642 |url-status=live }}</ref>
Drilling through the debris in the tunnel was stopped on 17 November after cracking sounds were heard. Alternative access tunnels have been started parallel and adjacent to the existing main tunnel. A further approach which is in preparation would involve drilling down from the surface of the terrain above the tunnel.<ref>{{cite news |title=Rescuers to drill new tunnels for trapped India workers |url=https://www.bbc.com/news/world-asia-india-67471018.amp |work=BBC News |date=20 November 2023 |access-date=20 November 2023}}</ref>
Three pipes were drilled during the operation, one providing oxygen, one providing passage for dry food, and a {{Convert|6|in|cm}}-wide pipe that was used to supply hot meals and allow the insertion of an endoscopic camera.<ref name=":0">{{Cite web |date=2023-11-21 |title=41 workers stuck in a tunnel in India for 10th day given hot meals as rescue operation shifts gear |url=https://apnews.com/article/india-uttarakhand-tunnel-collapse-tarpped-workers-ac1d8260ebd3246b519ebf54b2b0ebd3 |access-date=2023-11-22 |website=AP News |language=en}}</ref>
On 21 November, it was reported that communication with (and supply to) the trapped workers using a wider pipe had been established. The pipes had been used to provide dried fruits and other foods (including hot meals consisting of rice and lentils), oxygen, and other essentials to the men along with a small flexible camera to film and communicate with them. At this stage, as well as drilling through the rubble in the tunnel, there were efforts to drill three vertical shafts.<ref>{{cite web |title=Uttarakhand tunnel collapse LIVE updates: Govt releases regionwise list of trapped workers |url=https://www.hindustantimes.com/india-news/uttarakhand-tunnel-collapse-live-updates-today-november-21-uttarkashi-rescue-operations-trapped-workers-101700530620646.html |website=Hindustan Times |access-date=21 November 2023 |language=en |date=21 November 2023}}</ref><ref>{{Cite news |last=Clarance |first=Andrew |last2=Mollan |first2=Cherylann |date=2023-11-21 |title=Uttarakhand tunnel collapse: First video emerges of trapped Indian workers |language=en-GB |url=https://www.bbc.com/news/world-asia-india-67482481 |access-date=2023-11-21}}</ref><ref name=":0" />

== Investigation ==
The Uttarakhand government has formed a six-member expert committee to investigate the cause of the collapse of the section of tunnel. The committee, led by the Director of Uttarakhand Landslide Mitigation and Management Centre, will examine the reasons for the collapse in the Silkyara Tunnel.<ref>{{cite news |title=Uttarakhand forms expert committee to investigate Uttrakashi tunnel collapse |url=https://timesofindia.indiatimes.com/city/dehradun/uttarakhand-forms-expert-committee-to-investigate-uttrakashi-tunnel-collapse/articleshow/105204094.cms |access-date=17 November 2023 |work=The Times of India |date=14 November 2023 |archive-date=17 November 2023 |archive-url=https://web.archive.org/web/20231117002742/https://timesofindia.indiatimes.com/city/dehradun/uttarakhand-forms-expert-committee-to-investigate-uttrakashi-tunnel-collapse/articleshow/105204094.cms |url-status=live }}</ref>
