National high way

A National Highway is a main public road that connects major cities, towns, ports, and important regions of a country. It is usually managed and maintained by the central (national) government, unlike local or regional roads that are managed by state or municipal authorities.

Key Features of National Highways:
• 🚗 Connects long distances – links states, capitals, industrial areas, and borders.
• 🛣️ Built for heavy traffic – wider roads with multiple lanes.
• 📍 Strategic importance – supports trade, defense, and tourism.
• 🏗️ Maintained by central authority (e.g., in India, by the National Highways Authority of India – NHAI).
• 🌍 Similar worldwide – for example:
• USA → Interstate Highways
• India → National Highways (NH)
• UK → Motorways

👉 Example: In India, NH 44 is the longest National Highway, running from Srinagar (Jammu & Kashmir) to Kanyakumari (Tamil Nadu).
