National Highway 1D (NH 1D), also known as Srinagar–Leh Highway, was a National Highway in the state of Jammu and Kashmir that connected Srinagar to Leh in Ladakh. The Srinagar-Leh Highway was declared as National Highway in 2006. It is now part of National Highway 1 that extends west to Uri.
The old Central Asian trade route Srinagar–Leh–Yarkand was also known as the Treaty Road, after a commercial treaty signed in 1870 between Maharaja Ranbir Singh and Thomas Douglas Forsyth.
