The Indian Army and Border Roads Organisation (BRO) have successfully completed and opened a Bailey bridge over the Teesta River at Sanklang in North Sikkim. This crucial temporary structure, inaugurated on April 23, 2025, marks a turning point for the state’s recovery efforts following the catastrophic flash floods that wreaked havoc in October 2023.
The newly constructed bridge, spanning 150 feet, has reinstated critical road connectivity to the Mangan district, the administrative heart of North Sikkim. With this development, the Indian Army and local authorities have effectively reopened a vital lifeline that was severed for nearly six months, leaving thousands of residents isolated and emergency services crippled.
The Aftermath of a Disaster
In October 2023, Sikkim was struck by one of its worst natural disasters when a glacial lake outburst flood (GLOF) triggered a deluge that destroyed key infrastructure, including several bridges and roads along the Teesta River. The disaster cut off large swathes of North Sikkim, rendering areas like Chungthang, Lachen, and Lachung virtually inaccessible by road.
The sudden collapse of the old bridge at Sanklang worsened the crisis, stalling the movement of relief materials, cutting off strategic military routes, and isolating civilian populations dependent on these routes for essential supplies. The destruction also raised concerns regarding the vulnerability of Himalayan infrastructure in the face of increasingly frequent climate-related events.
Swift Military and Civilian Response
Recognizing the urgency of the situation, the BRO, in coordination with the Indian Army and local civil administration, initiated the rapid construction of a Bailey bridge at Sanklang. These prefabricated, portable steel bridges, originally designed for military use during World War II, are known for their quick deployment capabilities—making them the ideal solution for post-disaster infrastructure restoration.
The construction of the bridge was no small feat. Working against rugged terrain, unpredictable weather, and logistical challenges, engineers and army personnel raced against time to complete the project. The successful completion within a few weeks is a testament to the synergy between military efficiency and engineering prowess.

Reconnecting Lives and Livelihoods
With the bridge now operational, light vehicular traffic has resumed, allowing the movement of essential supplies, medical aid, and personnel into the previously cut-off regions. This will significantly bolster relief efforts and restore access to health care, education, and markets for the local population.
For residents of Mangan and surrounding areas, the opening of the bridge is more than a logistical achievement—it is a symbol of resilience and hope. Farmers can now transport their produce, students can return to schools, and medical emergencies can once again be handled with promptness.
From a strategic standpoint, the bridge is vital for maintaining security and operational readiness in the sensitive border region. The Indian Army’s ability to quickly respond and restore access reinforces its commitment to national security and civilian welfare alike.
Looking Ahead: Need for Sustainable Infrastructure
While the Bailey bridge is a temporary solution, it raises important questions about the sustainability and resilience of infrastructure in ecologically fragile zones. Experts and policymakers have emphasized the need for a long-term plan involving climate-resilient construction, improved early warning systems, and better urban planning to mitigate future disasters.
The Sikkim government has already initiated talks with the central government for funding and technical support to rebuild permanent, disaster-resilient infrastructure in the region. In the meantime, the Bailey bridge stands tall—an embodiment of unity, coordination, and the indomitable spirit of the people and forces working together for a common cause.
The reopening of the Bailey bridge over the Teesta River is a defining moment for North Sikkim—a reminder that even in the wake of devastation, rebuilding is possible when communities, engineers, and soldiers unite. It’s not just a bridge of steel and bolts; it’s a bridge of resolve, determination, and the collective will to move forward.
