Persistent monsoon rainfall continued to affect transportation across Sikkim on July 9, triggering landslides and disrupting road connectivity in several districts.
According to the Sikkim Police Control Room’s latest Road Situation Report, authorities have blocked multiple roads due to landslides, while maintenance work has also led to temporary closures. Consequently, officials have urged travellers to exercise caution before starting their journey.

Despite heavy rainfall, all roads under Gangtok district remain open for vehicular movement.
However, conditions continue to remain under close observation as rainfall persists across the region.
Pakyong District Faces Landslide Disruption

Meanwhile, officials confirmed that all other roads in the district remain open and accessible.

Most roads in Mangan district continue to operate normally despite the adverse weather.
Routes connecting Mangan to Gangtok via Rakdung-Tintek and Phodong, along with roads leading to Chungthang, Lachung, Yumthang, and Gurudongmar, remain open.
However, the Chungthang–Lachen Road remains blocked at Taramchu. Additionally, authorities reported cloudy weather conditions throughout the district.

The closures will remain in effect while engineers carry out maintenance work on the steel bridge over Chudharey Khola. Meanwhile, all other roads in the district remain open.
Fresh Landslides Hit NH-10
Fresh landslides have once again disrupted traffic on National Highway-10 (NH-10), which serves as Sikkim’s lifeline connecting the state with Siliguri.
Authorities reported road blockages at 29th Mile, Break Dara, and Hanuman Mandir along the Rangpo–Siliguri stretch.
As a result, officials have advised commuters to use the Darjeeling–Teesta route until restoration work is completed.
