Overview

• Officials invoked Section 33 of the Control of National Highways (Land and Traffic) Act, 2002 to suspend all traffic on the 52.1 km NH-10 corridor between Sevoke and Rangpo until 9 AM on August 8.
• The closure covers the Coronation Bridge–Chitrey section, where heavy rains triggered a major collapse at Sethijhora and worsened a cave-in at Swetijhora, making the route unsafe.
• Repeated landslides and persistent Teesta riverbank erosion have undermined embankment stability, prompting authorities to withhold reopening until repairs strengthen vulnerable slopes.
• NHIDCL and district administrations have arranged costlier, longer detours via Rangpo–Munsong–Algarah–Lava–Gorubathan–Sevoke and Rangpo–Chitrey–Kalimpong to ensure the flow of goods and passengers.
• Authorities say the extended suspension is essential to prevent accidents and safeguard travelers and supply chains until repair crews stabilize the most hazardous stretches.
