A portion of an under-construction tunnel of the Char Dham all-weather highway project collapsed in Uttarkashi district, Uttarakhand. Around 40 laborers are feared trapped inside. Rescue teams are working to reach them and provide oxygen and food supply. The tunnel, part of the project to widen roads connecting four Himalayan shrines, is one of the longest tunnels and will reduce the distance between Uttarkashi and Yamunotri by 26km. The collapse occurred near the Silkayara side of the tunnel, but there is a safe space between the landslide area and the tunnel's dead-end.A portion of an under-construction tunnel of the Char Dham all-weather highway project collapsed in Uttarkashi district, Uttarakhand.
