Opening of Taram Chu

Recently during the 1st week of March 2026, Taram Chu bridge construction got compeleted and since 8th March 2026 tourist permits are being given so that vehciles can pass through. But again on 5th April there was road damage and due to this road access to Lachen remained blocked from 15th April 2026 onwards. But from 10th September 2026, the road has been opened after repair work. 

North Sikkim Connectivity Update - Sep 2026

The strategically important Chungthang–Lachen road has reopened on 10th September after approximately four months of disruption, restoring a crucial road link to Lachen and the forward areas of North Sikkim.

The road was severely damaged on April 5, when a major formation breach near Taram Chu Bridge cut off access to the approach of the 400-foot Bailey suspension bridge. The route had previously been restored in February following damage caused by the October 2023 Glacial Lake Outburst Flood (GLOF), but was disrupted again in April.

The reconstructed stretch was formally reopened on August 29 by Sikkim Minister and area MLA Samdup Lepcha, in the presence of Mangan district administration officials, Project Swastik, GREF personnel and local representatives.

The reopening is particularly significant for Lachen's local economy and tourism sector. Lachen is the gateway to Gurudongmar Lake, one of Sikkim's most important high-altitude tourist destinations. The prolonged closure had severely affected local residents, transporters, homestays, hotels and other tourism-dependent businesses.

Important update for tourists

While the road to Lachen has now been restored and reopened since 10th September 2026, tourist vehicle permits for the Lachen/Gurudongmar route have been resumed. The authorities are expected to take some time to assess the newly restored road and put the necessary arrangements in place before tourist vehicles are permitted to operate on the route.

For now, the reopening is an important first step towards the gradual revival of tourism in North Sikkim, particularly for Lachen and the Gurudongmar Lake circuit. Travellers planning a trip should check the latest permit and road conditions before confirming their itinerary.

The situation remains dynamic, and OurGuest will continue to monitor the road and permit status and update travellers as soon as tourist access to Lachen and Gurudongmar officially resumes.
