Manali to Atal Tunnel Rohtang Length (Atal Tunnel ki Lambai)

The tunnel cuts the time and distance between Manali and Keylong on the way to Leh, and the route, which previously passed through Gramphu, used to take 5 to 6 hours in excellent weather. The former route had a length of 116 kilometres. A traveller can now travel from Manali to the tunnel’s South Portal in about 45 minutes, covering a distance of 24.4 kilometres. The 9.02-kilometre long tunnel takes around 15 minutes to travel through, and the revised route via the tunnel reduces the overall distance travelled to 71 km. In roughly 2 hours, you can travel this distance. When compared to the previous route, the time saved is approximately 3 to 4 hours. The tunnel avoids most of the areas where roadblocks, avalanches, and traffic jams were common.

About Atal Tunnel Weather and Temperature for UPSC Exams

The New Austrian tunnelling method was used to construct the tunnel. A semi-transverse ventilation system has also been installed. Large fans move air separately across the tunnel in a semi-transverse ventilation system. The cross-section of the tunnel also includes a 2.25 m tall and 3.6 m wide emergency tunnel. It is supposed to be beneath the main highway and used for emergency evacuation.
Fires will be contained within a 200-meter radius of the tunnel. At certain locations, even fire hydrants are available. A public announcement system is also installed in the tunnel to make critical announcements in the event of an emergency.
Heavy snowfall in the Rohtang Pass area is a serious issue, and avalanche control facilities have been built to avoid any damage to the roadways and to assure the safety of road and tunnel users alike. Because the Atal tunnel is projected to see a lot of traffic, CCTV cameras have been installed at regular intervals throughout the tunnel. For vehicle control and pollution monitoring, these CCTV cameras are connected to two monitoring rooms on both ends of the tunnel. Pollution sensors regularly monitor the tunnel’s air quality. Fresh air is fed into the tunnel by two heavy-duty blowers on each side of the tunnel if the air quality falls below the desired level.

According to the meteorological center, the maximum temperature of the Atal Tunnel is 6 to 7 degrees below normal. At 6.6 degrees Celsius, Keylong was the coldest inhabited place in Himachal. The minimum temperature in Shimla was 13.7 degrees C and the minimum temperature in Dalhousie was recorded at 12.5 degrees C.

Atal Tunnel: Challenges in Construction

The most difficult duty was continuing the excavation under heavy snowfall in the winter, and tunnelling excavation was done from both ends. The north portal was not accessible during the winter since the Rohtang pass closed during the winter, hence the excavation was done solely from the south portal.
Other obstacles to the tunnel’s progress included issues disposing of almost 8 lakh m3 of excavated rock and soil, the heavy incursion of water, more expensive treatment, and a slowing of excavation from 5 metres per day to half a metre per day. There were also unstable rocks that hindered the blasting and excavating even more. A cloudburst and flash flood also killed 42 workers who were working on the makeshift access road.

अटल सुरंग

रोहतांग सुरंग अटल सुरंग का दूसरा नाम है। यह हिमालय की पूर्वी पीर पंजाल श्रेणी में रोहतांग दर्रे के नीचे बनी एक सड़क मार्ग सुरंग है। यह भारत के हिमाचल प्रदेश में लेह-मनाली राजमार्ग पर स्थित है। अटल सुरंग का नाम भारत के पूर्व प्रधान मंत्री अटल बिहारी वाजपेयी के नाम पर रखा गया है।

यह दुनिया की सबसे लंबी सड़क मार्ग वाली सिंगल-ट्यूब टनल है, जिसकी लंबाई 10,000 फीट है, जिसकी लंबाई 9.02 किलोमीटर है। लेह-मनाली राजमार्ग और निम्मू-पदुम-दारचा सड़क खंड मौजूदा अटल सुरंग के पूरा होने और निर्माणाधीन शिंगो ला सुरंग के पूरा होने के बाद सभी मौसम में सड़क बन जाएंगे। इसके 2024 तक पूरा होने की उम्मीद है।

सुरंग लेह के रास्ते में मनाली और केलांग के बीच के समय और दूरी को काटती है, और मार्ग, जो पहले ग्राम्फू से होकर गुजरता था, उत्कृष्ट मौसम में 5 से 6 घंटे लगते थे। पूर्व मार्ग की लंबाई 116 किलोमीटर थी। एक यात्री अब मनाली से सुरंग के दक्षिण पोर्टल तक लगभग 45 मिनट में 24.4 किलोमीटर की दूरी तय कर सकता है। 9.02 किलोमीटर लंबी सुरंग के माध्यम से यात्रा करने में लगभग 15 मिनट लगते हैं, और सुरंग के माध्यम से संशोधित मार्ग कुल दूरी को 71 किमी तक कम कर देता है। करीब 2 घंटे में आप यह दूरी तय कर सकते हैं। पिछले मार्ग की तुलना में, बचा हुआ समय लगभग 3 से 4 घंटे है। सुरंग उन अधिकांश क्षेत्रों से बचाती है जहाँ सड़कें, हिमस्खलन और ट्रैफिक जाम आम थे।
