Rohtang tunnel to be open for traffic by 2020

Manali, June 17: Construction of Rohtang tunnel, one of the world’s most challenging motorable projects at 3,000 metres above sea level and which will provide an all-season connectivity to the landlocked Lahaul Valley from here in Himachal Pradesh, may be completed by 2020. The most ambitious and expensive undertaking of its kind, the excavation of the 8.8-km long horseshoe shaped tunnel under the 3,978 metres Rohtang Pass in the Himalayas was completed last October. Now civil engineering work is on. However, a geological surprise in the form of a rivulet that sprung up in 2012 during the tunnel digging is posing a challenge. Its torrential inflow is emerging into the tunnel. “As per the current pace of work, most likely we will complete all civil engineering work by December 2019,” an engineer involved in the tunnel construction told IANS.

He said electrical and ventilation works were also in progress simultaneously. “In all probabilities, the tunnel will be made operational by May-June 2020.” The project is being built by the Border Roads Organisation (BRO), a wing of the Defence Ministry, in collaboration with Afcons, a joint venture with Strabag AG. The Rs 1,495-crore tunnel’s foundation stone was laid by United Progressive Alliance (UPA) chairperson Sonia Gandhi on June 28, 2010 in the picturesque Solang Valley near here.
The tunnel, whose both ends can be accessed after negotiating 20 landslide and snow avalanche zones, is located at altitudes ranging above 3,000 metres and lies beneath the snow covered Rohtang Pass, whose 70 per cent of the top remains under snow even during summer. Situated in the Pir Panjal ranges, the Rohtang Pass highway tunnel will provide ample room for two-way traffic and is designed to cater to a maximum vehicular speed of 80 km per hour. Upon completion, it will also be a boon for the cold deserts of Lahaul Valley, where over 20,000 people remain cut off from the rest of the country in winter owing to the closure of the Rohtang Pass.

The completion of the Rohtang tunnel is a key element in the Defence Ministry’s attempts to make the entire 475 km-long Manali-Keylong-Leh highway, used by the armed forces to reach forward areas in Ladakh bordering China and Pakistan, motorable round the year, said officials. The strategic importance of the Manali-Leh link was realised by the Indian government almost a decade ago when Pakistan tried to cut off the Srinagar-Leh road during the Kargil conflict, in a bid to restrict road access to Ladakh.
