Continuous rainfall across Sikkim and the Darjeeling hills has caused the Teesta River to breach its embankment at 29th Mile, inundating a critical stretch of National Highway 10 (NH-10), the lifeline linking Sikkim and Kalimpong to Siliguri. This has severed road connectivity to Sikkim, as well as the Kalimpong and Darjeeling districts of West Bengal, according to officials. Traffic also came to a halt on the Peshok Road, which connects Darjeeling to Kalimpong.
