The Chenani-Nashri tunnel on Jammu-Srinagar National Highway, which Prime Minister Narendra Modi has dedicated to the nation this Sunday, is the India’s first and the world’s sixth tunnel to have transverse ventilation system, providing fresh air to passengers. The tunnel, constructed at a cost of Rs 2,519 crore, will reduce the distance between Jammu and Srinagar – the twin state capitals – by 30 km, while ensuring safe and swift passage for commuters, even in adverse weather conditions. To ensure smooth travel and safety of commuters, the ABB has designed, engineered and supplied low harmonics variable speed drive (VSD) system for tunnel ventilation.
