National Highway 22 (India)(old numbering)

National Highway 22 (NH 22) is a 459 km (285 mi)National Highway in Northern India that runs from Ambala through Chandigarh and Himachal Pradesh up to Khab on the Tibet border. It is also known as Hindustan Tibet road.

Description

Starting in Ambala, in northern Haryana as an offshoot of NH 1, the NH 22 runs north towards Zirakpur, outside Chandigarh. This first 40 km stretch, running partly through eastern Punjab, is named as the Ambala Chandigarh Expressway, and is a modern and well-maintained four lane section with several bridges and three major flyovers.

At Zirakpur, it meets NH 64, and turns north-east through Panchkula to Pinjore, where the NH 21A heads north-west, then to Kalka and Parwanoo. The expressway has now been extended to bypass the towns of Pinjore and Kalka, which were previously a major traffic bottleneck point.

After Kalka, the highway enters Himachal Pradesh, and as the terrain changes it becomes a mountain road with extensive hairpin turns. It continues north-east to Solan, and then north to Shimla, where it joins the NH 88. Between Kalka and Shimla, several sections run near the Kalka-Shimla Railway. From Shimla, it heads approximately north-east towards the Chinese frontier, reaching the border town of Khab just before the Line of Actual Control. Beyond Khab, the road runs for a short distance through Namgial to the Shipki La pass, where it enters Chinese territory.
