Nimmu–Padum–Darcha road

Nimmu–Padum–Darcha road (NPD road) or Zanskar Highway is a road between the Indian union territory of Ladakh and the state of Himachal Pradesh, passing through the region of Zanskar. It connects Nimmu in the Indus Valley to Padum, the capital of Zanskar, and to Darcha village in Lahul and Spiti. It provides an alternative to the Leh–Manali Highway in linking Ladakh with the rest of India. It was built by the Border Roads Organisation (BRO) of the Indian Army. The construction of road was completed in March 2024. The already completed Atal tunnel, and the under-construction unidirectional-twin-tube 4-lane Shingo La Tunnel, which is expected to be completed by 2027 will provide all weather connectivity and reduce the distance from Manali to Kargil by 522 km.

It is estimated that travel on this road will only take 10–12 hours to reach Leh from Manali, as opposed to the Leh-Manali highway taking almost 14–16 hours under good weather conditions. The road is strategic for the Indian Army as it is set back from the international border and can facilitate safe troop movements. The Nimmu-Padam Darcha road is just 298 km from Darcha in Himanchal Pradesh.
