Transport Corridors, Major Ports & Inland Waterways

India's multi-modal transport infrastructure underpins domestic economic integration and international maritime commerce. The road network, managed by the National Highways Authority of India (NHAI), includes landmark initiatives like the Golden Quadrilateral, North-South and East-West Corridors, and the Bharatmala Pariyojana. Indian Railways, organized into 18 administrative operational zones, operates one of the world's largest unified rail networks, currently modernizing via Dedicated Freight Corridors (DFCs). Maritime trade is facilitated by 12 Major Ports and over 200 non-major ports, with Jawaharlal Nehru Port (Nhava Sheva) and Deendayal Port (Kandla) handling major container and bulk cargo. Inland navigation is governed by the Inland Waterways Authority of India (IWAI) along designated National Waterways.
