 The Nagpur Plan defined State Highway as:
“State Highways should be the main arteries of commerce by road within a State or similar geographical unit. In places, they may carry heavier traffic than many of the National Highways, but this will not alter their designation or function”.
The Road Development Plan of India, 1981-2001, (Lucknow Plan) laid down the following policy and goal for State Highways:
“State Highways should be extended to serve district headquarters, sub-divisional headquarters, major industrial centres, places of commercial interest, places of tourist attraction, major agricultural market centres and ports”.
The Lucknow Plan also envisaged that the NH and SH network should link all towns with a population of 5000 and above.
In the Indian Roads Congress document on Geometric Design Standards for Rural (Non-Urban) Highways, IRC: 73-1980, the following definition has been given:
“State Highways are arterial routes of a State linking district headquarters and important cities within the State and connecting them with National Highways or highways of the neighbouring States”.
A Strategic Options Study (SOS) was undertaken by the Department in 2009 based on which the State Highways and Major District Roads in the State was formulated. The list of State Highways is as below:
