Leh is connected to the rest of India by two high-altitude roads both of which are subject to landslides and neither of which are passable in winter when covered by deep snows. The National Highway 1D from Srinagar via Kargil is generally open longer. The Leh-Manali Highway can be troublesome due to very high passes and plateaus, and the lower but landslide-prone Rohtang Pass near Manali. The third road axis is under construction.
