India is set to achieve a major infrastructure milestone as the excavation of the ambitious Zojila Tunnel reaches its final breakthrough stage. Once operational, the Zojila Tunnel will become the world's longest single-tube, bi-directional road tunnel at such a high altitude, transforming travel and transportation in one of India's most challenging regions. The Zojila Tunnel is a 13.15-kilometre-long road tunnel being built beneath the famous Zojila Pass on the Srinagar-Kargil-Leh highway.
