Prime Minister Narendra Modi on April 2nd inaugurated the Chenani - Nashri tunnel, which is India’s longest and Asia’s 6th longest and dedicated to the nation. It is an all-weather route with transverse ventilation system cutting down the Chenani-Nashri distance from from 41 km to 9.2 km. The bi-directional tunnel is built with a budget of 2519 crore that allows travelers to bypass the areas susceptible to landslides (44 avalanche spots). The interesting facts about this tunnel are presented below.
1. Revenue
The National Highways Authority of India has built the project with a whooping budget of Rs 3,720 crore. As it is an all-weather tunnel, it will boost revenue in the state by increasing both tourism and trade. However because the tunnel bypasses three major halts on the National Highway, the residents of those 3 areas raises objections which were taken into account by J&K government which promised to arrange rehabilitations for small businesses.
Daily fuel savings due to this tunnel would be approximately 27 lakhs, official sources said.
2. Technology
ABB, which is a global leader in industrial technology, is responsible for the transverse ventilation and other features of the tunnel using ABB drives and ABB software. ABB takes care to maintain clear and fresh air and tolerable co2 levels and to exhaust the harmful vehicle emissions. For tunnel ventilation which is required for the smooth and safe travel of the passengers, ABB used Variable Speed Drive (VSD) technology for tunnel ventilation.
New Austrian Tunneling Method (NATM) is used for tunneling process which is currently famous. It is also known as Sequential Excavation Method (SEM).
