Zoji La
Explanation
Mountain passes in the Himalayan region are critical for strategic and civilian connectivity. The National Highway 1A (under the old numbering system, now part of National Highway 1) serves as the primary land route connecting the Kashmir Valley to the Ladakh region.
Detailed Analysis of Options:
- Rohtang La Rohtang La: This pass is located in the Pir Panjal range of the Himalayas. It connects the Kullu Valley with the Lahaul and Spiti Valleys of Himachal Pradesh. It does not connect the Kashmir Valley to Leh.
- Zoji La Zoji La: Located in the Great Himalayan Range, Zoji La provides the vital link between Srinagar (in the Kashmir Valley) and Leh (in Ladakh). The highway passing through this pass was historically designated as National Highway 1A (now NH 1). It is often closed during winter due to heavy snowfall.
- Baralacha La Baralacha La: Situated in the Zanskar range, this pass connects the Lahaul district in Himachal Pradesh to the Leh district in Ladakh. It is located along the Leh-Manali Highway.
- Tanglang La Tanglang La: This is a high mountain pass located in the Ladakh region. It lies on the Leh-Manali highway, further north towards Leh, but does not connect the Kashmir Valley to Leh.
Key Takeaway:
Zoji La is the strategic mountain pass that connects Srinagar (Kashmir Valley) to Leh (Ladakh) and is traversed by the historic National Highway 1A (currently NH 1).
