Troops of Trishakti Corps Indian Army along with BRO and assistance of civil administration and locals are undertaking operations at a massive scale to reconnect North Sikkim. While BRO is trying to reconnect the main route Mangan-Tung-Chungthang, troops of Trishakti Corps along with BRO and the assistance of locals and civil administration are making efforts to open up the alternate route Mangan- Sanklang – Theng – Chungthang. This requires the construction of two bailey bridges over the Teesta River at Mangan-Sanklang Crossing. Working round the clock, the first bridge has been completed on 22 Oct 2023.<br />'' <br />'' Areas of North Sikkim ahead of Mangan have remained cut off since 4th Oct. As an immediate response, footbridges and zip lines were constructed at Chungthang and Sanklang-Mangan Crossing. These have enabled the movement of people on foot and the provision of relief material through the zip lines established.  Due to large-scale damage to the main road Mangan-Tung-Chungthang, a fresh alignment of the road through Naga Village is being made before the damaged bridge site at Toong can be approached and a new bridge constructed. This will take time.<br />'' <br />'' According to Defence PRO in Guwahati, as an immediate relief to restore connectivity up to Chungthang via the alternate route Mangan- Sanklang- Theng – Chungthang, troops of Trishakti Corps are undertaking the construction of the bailey bridge at Mangan-Sanklang Crossing, 200 metres upstream of where a bamboo bridge and Zipline was constructed earlier. However, the width of the river has increased to 600 feet and water runs along two channels with a 160 feet island in between. The decision was therefore taken to construct two separate bridges. Working on a war footing, the troops of the Trishakti Corps finished construction of the 150-foot-long first bridge yesterday. The second bridge is likely to be completed by Friday.
