Spur Route - India

India

The Indian National Highway system designates spur routes of the main National Highways with alphabets. For example, National Highway 1 has four spur routes: NH 1A, NH 1B, NH 1C and NH 1D, the shortest of which is just six km in length (NH 1C) and the longest is 663 km (NH 1A). While the spur routes essentially originate at the parent National Highway, they are not merely secondary in status as some of the spur routes serve important cities in India. For example, Srinagar, the capital of the state of Jammu and Kashmir, is served by the spur route NH 1A. Some spur routes are specifically used to connect important Indian ports: NH 5A links Paradip with its parent NH 5, and NH 7A links Tuticorin with NH 7).
