The World’s longest Highway tunnel — Atal Tunnel (9.02 Km) has been built by Border Road Organisation. This tunnel connects Manali to Lahaul-Spiti valley throughout the year. Earlier the valley was cut off for about 6 months each year owing to heavy snowfall. The Tunnel is built with ultra-modern specifications in the Pir Panjal range of Himalayas at an altitude of 3000 metres from the Mean Sea Level (MSL). Golden Quadrilateral comprises construction of 5,846-km long 4/6 lane, high density traffic corridor, to connect India’s four big metro cities of Delhi-Mumbai-Chennai-Kolkata.
