Manali: Prime Minister Narendra Modi will inaugurate the world longest highway Atal Tunnel in Rohtang of Himachal Pradesh at 10 hours on Saturday.

The 9.02 Km long tunnel will connect Manali to Lahaul-Spiti valley throughout the year.

Prior to this, the valley was cut off for about 6 months every year in the wake of heavy snowfall.

The Tunnel is built with ultra-modern specifications in the Pir Panjal range of Himalayas at an altitude of 3000 Mtrs (10,000 Feet) from the Mean Sea Level (MSL). The tunnel reduces the road distance by 46 Kms between Manali and Leh and the time by about 4 to 5 hours.

The South Portal (SP) of the Atal Tunnel is located at a distance of 25 Km from Manali at an altitude of 3060 Mtrs, while the North Portal (NP) of the tunnel is located near the village Teling, Sissu, in Lahaul Valley at an altitude of 3071 Mtrs.

It is a horseshoe-shaped, single tube double lane tunnel with a roadway of 8 Mtrs. It has an overhead clearance of 5.525 Mtrs.  It is 10.5-meter wide and has a 3.6 x 2.25 Mtrs fireproof emergency egress tunnel built into the main tunnel itself.

Atal Tunnel has been designed for a traffic density of 3000 cars per day and 1500 trucks per day with a maximum speed of 80 km/hr. 

It has a state-of-the-art electromechanical system including semi transverse ventilation system, SCADA controlled firefighting, illumination, and monitoring system. 

The historic decision to construct a strategic tunnel below the Rohtang Pass was taken on June 03, 2000, when late Atal Bihari Vajpayee was the Prime Minister.

The foundation stone for the access road to the South Portal of the tunnel was laid on May 26, 2002.

The Border Roads Organisation (BRO) worked relentlessly to overcome major geological, terrain, and weather challenges that included the most difficult stretch of the 587-meter Seri Nalah Fault Zone.

The breakthrough from both ends was achieved on October 15, 2017.

The Union Cabinet met under the chairmanship of Prime Minister Narendra Modi on December 24, 2019 and decided to name the Rohtang Tunnel as Atal Tunnel to honour the contribution made by the former Prime Minister Atal Bihari Vajpayee.

After attending the inauguration function of the Atal Tunnel at South Portal, Manali, Prime Minister Narendra Modi shall be participating in public functions at Sissu in Lahaul Spiti and at Solang Valley.
