Gangtok,Nov12:Tunnel to remove traffic bottleneck on Sikkim highway Sikkim chief minister Pawan Chamling with two Border Roads Organisation officials after he laid the foundation stone of an 80-metre-long tunnel in Bardang, a landslide-prone zone on National Highway 31A, on Wednesday. The tunnel at Bardang, 35km from Sikkim capital Gangtok, will be carried out by the Project Swastik of the BRO, which looks after the maintenance of the highway. The eight-metre wide and nine-metre high tunnel will be motorable for trucks and other heavy vehicles. The cost of the project will be Rs 6.77 crore. The area is a perpetual trouble spot on NH31A and BRO personnel often brave inclement weather and risk their lives to clear the stone, muck and debris that block the highway after landslides. ‘The highway at Bardang gets closed frequently in monsoon because of landslides. Removing the debris and constructing walls along the hills for traffic are temporary measures, which we have been doing so far. Now a tunnel has been planned,’ said Project Swastik Brigadier RK Patyal. .
