Himachal Pradesh, although railways and airways serve very limited transport needs, the road network of the state serves the transport needs of the people. Although, the geography of Himachal presents considerable challenge to the development of transport infrastructure, it has the highest road density among all the Hill States of India. Himachal also has 3 airports, 2 narrow gauge rail tracks and couple of other under-construction broad gauge railway tracks, but roads remain the main mode of transport.
Kinnaur was opened up in the early 1960s with the completion of the NH-5 Hindustan-Tibet National highway from Ferozepur in Punjab to Shipki La. Lahaul was opened up in the late 1960s with the construction of roads over Rohtang pass. Lahaul is reachable via roads through high passes, such as Rohtang (3,967 m, 13,050 ft), Kunzum (4,600 m, 14,913 ft) and Baralarcha (4,300 m, 14,000 ft). The building an efficient transport system was the top most priority in the first Five year plan. In January 1991, Himachal was linked up with the broad gauge system by extending the Delhi-Nangal rail line.
The geography of Himachal presents considerable challenge to the development of transport infrastructure. The border districts, located near the borders of Tibet and Indian union territories of Ladakh and Jammu and Kashmir, such as Kinnaur, Lahaul, Spiti and the Pangi and Bharmour tehsils of Chamba districts are the major underdeveloped and underserved tribal areas of the state. Other underdeveloped areas include Shillai in Sirmaur district, and deep cut-off valleys in the Kullu and upper stretches of Kangra districts. Spiti is a cold desert and underdeveloped area. Due to poor accessibility, life in these areas had grown in isolation.
The government-owned Himachal Road Transport Corporation runs a good all-weather network of buses inter & intra state including the remotest of the corners of the state. Himachal Pradesh being a major tourist destination, there is no dearth of private buses and taxis.[1]
Most tourist spots in Himachal Pradesh such as Shimla, Manali, Dharamsala etc. are well connected by roads. Some of the roads in Himachal are seasonal and get closed during winters and monsoons due to heavy snowfall, landslides and washouts.[2][3]
National Highways (NH) with total 1235 km length in Himachal are:
All these airports have runways shorter than 5000 ft and therefore only allow the operation of smaller aircraft such as the Bombardier Dash 8, 42 seater ATR & 70 seater ATR.
