Chenani-Nashri tunnel is India's longest, and safest

According to Chandwar, who has been monitoring every development related to construction of the tunnel, at every 75 metres there is a video surveillance monitor through which cameras will help in detection of any "suspicious acts" by anyone inside the tunnel. "There is a tube to provide fresh air. Everything is well managed," said Chandwar.According to official statistics, the entire project was completed in five years and it was closely monitored by the Ministry Of Road, Transport and Highways.
