Safety measures

Atal Rohtang tunnel was built using the New Austrian tunnelling method and has been equipped with a semi-transverse ventilation system, and large fans separately circulated air throughout the tunnel. A 2.25 m tall and 3.6 m wide emergency tunnel has been integrated into the tunnel cross-section to subordinate the superhighway for the removal of emergencies. Fires hazards inside the tunnel will be controlled within an area of 200 metres and fire hydrants are provided at specific locations throughout the tunnel. The tunnel also has a public announcement system to make an important announcement in emergencies for which loudspeakers are installed at regular intervals. Heavy snowfall in the Rohtang Pass area is a major issue, especially on the roads of the main tunnel. To prevent any damage to the roads and to ensure the safety of the roads and tunnel users alike, snowslide control structures have been constructed. Since the Atal tunnel is likely to witness heavy traffic, CCTV cameras are placed at regular intervals in the tunnel which are connected to two monitoring rooms on both ends of the tunnel for vehicle management and pollution monitoring.
