Project Overview

The 12 m diameter tunnel bypasses the Rohtang Pass on the Manali-Leh Highway, and provides all-weather connectivity to the Lahaul Spiti Valley and northern India, reducing travel distance by 47 km and assisting economic development throughout the region. Previously, access over the mountain pass was restricted to only six to eight months each year, due to heavy snowfall, avalanches and landslides.
