Leh-Manali Highway

The Leh–Manali Highway is a 428 km (266 mi) long highway in northernmost India connecting Leh, the capital of the union territory of Ladakh, to Manali in the state of Himachal Pradesh. It connects the Manali Solang valley to the Lahaul and Spiti valleys in Himachal Pradesh and the Zanskar valley in Ladakh. It is open for only about five months in a year, from mid-May or June (when the snow is cleared from the highway) to October, when snowfall again blocks the high passes on the highway. However, the Lahaul valley will now remain connected to Manali for most part of the year through Atal tunnel.
The Leh–Manali Highway has been designed, built and being maintained by the Border Roads Organisation (BRO) of the Indian army. It supports the heaviest army vehicles.
