Understanding the Atal Tunnel: Location and Features

The question asks us to identify the correct statements regarding the Atal Tunnel. Let's carefully examine each statement to determine its accuracy.

The Atal Tunnel is a significant infrastructure project in India, providing crucial connectivity in the Himalayas. Understanding its key features and location is important.

Let's break down each statement:

Analyzing Statements about Atal Tunnel

• Statement A: It connects Manali to Lahaul and Spiti
  This statement is correct. The primary purpose of the Atal Tunnel is to provide all-weather connectivity between Manali in Himachal Pradesh's Kullu district and the Lahaul and Spiti valley. This connectivity significantly reduces travel time and provides access during winter months when the Rohtang Pass is snowbound.
• Statement B: It is the world's longest highway tunnel
  This statement needs clarification based on the common description. While the Lærdal Tunnel in Norway is the world's longest road tunnel overall, the Atal Tunnel is widely recognized as the world's longest highway tunnel located above 10,000 feet (3,048 meters). In the context of this question and common references, this statement is considered correct.
• Statement C: It has been built by Border Roads Organisation
  This statement is correct. The Border Roads Organisation (BRO), a statutory body under the Ministry of Defence, Government of India, was responsible for constructing the Atal Tunnel. Their expertise in building infrastructure in challenging mountainous terrains was crucial for this project.
• Statement D: It is constructed through Siwalik Himalaya
  This statement is incorrect. The Atal Tunnel is built under the Pir Panjal range of the Himalayas. The Pir Panjal range is part of the Lesser Himalayan region, whereas the Siwalik (or Outer Himalayas) is the southernmost and youngest range of the Himalayas.

Summary of Correct Statements

Based on our analysis:

• Statement A: Correct
• Statement B: Correct (in the context of a significant altitude)
• Statement C: Correct
• Statement D: Incorrect

The correct statements are A, B, and C.

Identifying the Correct Option

We need to find the option that includes only the correct statements (A, B, and C).

• Option 1: A, B and C only - This includes the three correct statements.
• Option 2: A and B only - This misses statement C.
• Option 3: A, C and D only - This incorrectly includes statement D and misses the nuances of statement B.
• Option 4: B, C and D only - This incorrectly includes statement D and misses statement A.

Therefore, the option listing A, B, and C only is the correct answer.

The construction of the Atal Tunnel has significantly improved connectivity, reduced travel time, and boosted economic activity and tourism in the region, particularly providing year-round access to the Lahaul and Spiti valley.

Additional Information about Atal Tunnel

The Atal Tunnel, named after former Prime Minister Atal Bihari Vajpayee, was inaugurated on October 3, 2020. It is a horseshoe-shaped, single tube, double lane tunnel. It is designed with advanced safety features and ventilation systems suitable for high altitude conditions. The tunnel bypasses the treacherous Rohtang Pass, making travel much safer and quicker. Before the tunnel, reaching Lahaul and Spiti during winter was extremely difficult due to heavy snowfall blocking the pass. The tunnel provides year-round access, greatly benefiting the local population, military movements, and tourism. Its strategic location also provides a vital link for defence forces in the border areas.
